1.1.2 Engine Heritage The LM6000 gas turbine is derived from the GE commercial CF6-80C2 aircraft engine. This engine first entered aircraft service in 1985 and is used extensively in wide-body commercial airliners. More than 2000 “80C2” engines are either on order or in use today. 1.1.3 Simple Design The LM6000 package is offered in a 50 Hz and 60 Hz design. This document covers the 60 Hz design. The LM6000 is a 2-shaft gas turbine engine equipped with a low-pressure compressor, high-pressure compressor, combustor, high-pressure turbine, and low-pressure turbine.

LM6000 Emissions Abatement Configurations 1.1.5 Output Enhancements Various options are available to improve the typical OUTPUT-MW profile of the LM6000 gas turbine. To improve high ambient temperature performance, either evaporative cooling or coils for mechanical chilling are available.= GE Energy will work with the customer to determine the applicability of of these enhancements to their particular case. 1.1.6 High Availability and Reliability The LM6000 gas turbine generator set has a proven record of high availability and reliability. With more than 700 units installed since 1992, the LM6000 gas turbine generator set leads the industry in reliability greater than 99.7%* and availability above 98.6%*. Each gas turbine is factory tested to full speed and full load for performance and mechanical integrity. Every package is static tested to check each system of the package. Refer to section 1.2.1 for static testing summary. Leveraging aircraft experience and design, the aeroderivative design approach incorporates features such as split castings, modular construction, individual replacement of internal and external parts, and GE’s “lease pool” engine program. The extensive use of high quality components common with its parent aircraft engine validates engine reliability and offers reduced parts cost. Various inspections and hot section repairs can be performed on the gas turbine at site within the turbine enclosure. The “Hot Section”,HPT and combustor, can be removed/replaced in the field within seventy-two hours allowing for greater availability during planned maintenance. Greater availability is achieved by the on-condition maintenance program, which inspects and repairs only as necessary to desired operational condition. * 50th percentile of 233 units reporting into ORAP® as of July 2007.

7. Mechanical Descriptions - Major Equipment
7.1 Turbine Engine
LM6000 Turbine Engine
The LM6000 is a 2-shaft gas turbine engine derived from the core of the CF6-80C2, GE's high thrust, high efficiency aircraft engine. More than eighteen hundred CF6-80C2s are in service and 2,000 or more are on order or option. The CF6-80C2 has logged more than 30,000,000 flight hours in the Boeing 747 and other wide-body aircraft, with a 99.88% dispatch reliability and commercial aviation's lowest shop visit rate. GE used this 30 million hour flight experience to create the LM6000. Both engines have a common design and share most major parts. The Low Pressure Turbine, High Pressure Compressor, High Pressure Turbine, and Combustor are virtually identical. This use of flight-proven parts, produced in high volume, contributes to the low initial cost and high operating efficiency of the LM6000.
LM6000 - 60 Hz Classic 6/2008 Page 34 of 156
7.1 Turbine Engine (Cont)
Major Engine Components:
• 5-stage low-pressure compressor (LPC) • 14-stage variable geometry high pressure compressor (HPC) • Annular combustor • 2-stage air-cooled high pressure turbine (HPT) • 5-stage low pressure turbine (LPT) • Accessory Gear Box The LM6000 has two concentric rotor shafts: The LPC and LPT are assembled on one shaft, forming the Low Pressure Rotor. The HPC and HPT are assembled on the other shaft, forming the High Pressure Rotor. The LM6000 uses the Low Pressure Turbine (LPT) to power the output shaft. By eliminating the separate power turbine found in many other gas turbines, the LM6000 design simplifies the engine, improves fuel efficiency and permits direct-coupling to 3600 rpm generators for 60 Hz power generation. The LM6000 gas turbine drives the generator via a flexible dry type coupling connected to the front, or “cold,” end of the LPC shaft.
7.1.1 Turbine Cycle
• Filtered air enters the bellmouth and flows through guide vanes to the LPC • LPC compresses air by 2.4:1 ratio • Air flows from LPC through the front frame & bypass air collector to HPC • Air enters HPC through Inlet Guide Vanes • The HPC compresses air by 12:1 ratio • 30 Fuel (SAC) nozzles or 75 fuel (DLE) nozzles mix air and fuel • Air-Fuel mixture is ignited in Annular Combustor • Hot combustion gases expand through HPT driving the HPC • Hot combustion gasses expand further through LPT driving the LPC and load • Flanged end of the LPC shaft drives the electric generator load. • Exhaust gasses exit engine/package at the exhaust flange
LM6000 - 60 Hz Classic 6/2008 Page 35 of 156
7.1.2 Inlet and IGV Section The turbine inlet straightens the air stream and directs it into the Low Pressure Compressor (LPC). 7.1.3 Low Pressure Compressor The Low Pressure Compressor (LPC) is a 5-stage axial flow compressor with a 2.4:1 pressure ratio. It is derived from the CF6-50 flight engine. A horizontally split casing provides access to blades and vanes. Borescope ports permit flow path inspection. 7.1.4 Bypass Air Collector The LM6000 matches the airflow between the Low Pressure (LP) and High Pressure Compressor (HPC) with 12 hydraulically actuated variable bypass valves mounted in the turbine front frame. During start-up and part-load operation these valves open partially and vent excess air to the bypass air collector. The bypass air collector also supports the accessory gearbox. 7.1.5 High Pressure Compressor The LM6000 High Pressure Compressor (HPC) is a 14-stage unit. Variable stators in stages 1-5 ensure high efficiency throughout the starting and operating range. The stator geometry of stages 6 through 14 is fixed horizontally. This allows ready access to the stator vanes and rotor blades for inspection or replacement. 7.1.6 Combustion Section 7.1.6.1 Singular Annular Combustor (SAC) Thirty nozzles feed fuel into the LM6000 annular combustor, providing a uniform heat profile to the High Pressure Turbine (HPT). This produces maximum output with low thermal stress. The swirler-cup dome design produces a lean thoroughly mixed, mixture in the primary zone of the combustor. This provides cleaner combustion and reduces NOX. Available nozzle designs allow natural gas, distillate or dual-fuel operation. The nozzles also permit NOX reduction with water injection (natural gas and distillate fuels) and steam injection (natural gas fuel only). The annular combustor design provides low pressure loss, low exit temperature and extended operating life. A Hastelloy X inner liner resists corrosion and extends combustor life. 7.1.6.1.1 Dry Low Emissions (DLE) Combustor
LM6000 - 60 Hz Classic 6/2008 Page 36 of 156
The DLE system controls NOx emissions without the use of water or steam. GE Energy installs special combustors, manifolds, nozzles and metering to control flame temperature and reduce emissions of NOx, CO and unburned hydrocarbons. This DLE system reduces emissions over the entire power range, not just at high power settings.
The fuel system hardware supplied with the DLE gas turbine includes a base mounted gas manifold, hoses, staging valves, and a set of thirty fuel premixers. The LM6000 DLE gas turbine utilizes a lean premix combustion system designed for operation on natural gas fuel as well as dual fuel. Gas fuel is introduced into the combustor via 75 air/gas premixers packaged in 30 externally removable and replaceable modules. The premixers produce a very uniformly mixed, lean fuel/air mixture. The triple annular configuration enables the combustor to operate in premix mode across the entire power range, minimizing nitrogen oxide (NOx) emissions even at low power.
The head end or dome of the combustor supports 75 segmented heat shields that form the three annular burning zones in the combustor, known as the outer or A-dome, the pilot or B-dome, and the inner or C-dome. In addition to forming the three annular domes, the heat shields isolate the structural dome plate from the hot combustion gases. The heat shields are an investment-cast superalloy and are impingement and convection cooled. The combustion liners are front mounted with thermal barrier coating (TBC) and no film cooling.
Fuel to the gas turbine will be controlled based on control mode, fuel schedules, and the load condition. For normal start sequence (13 minutes), gradual load changes are preferred with at least 5-minute ramp from idle to maximum power. If a fast start (10 minutes) is required, the load may be ramped from idle to full load in 4 minutes as part of the start sequence provided in Operation. Normal load reduction transients should be no faster than 2-3 minutes from maximum power to synchronous idle. 7.1.7 High Pressure Turbine The High Pressure Turbine (HPT) is a 2-stage, air-cooled turbine rotated by the hot gasses exiting the combustor. The HPT powers the High Pressure Compressor (HPC) to supply high-pressure air to the combustor. Turbine disks, blades and stator are air-cooled for efficiency. Blades are coated to resist erosion and corrosion. 7.1.8 Low Pressure Turbine The 5-stage Low Pressure Turbine (LPT) receives the outlet flow from the HPT. The LPT drives the Low Pressure Compressor and the driven load (generator, compressor, etc.) through a shaft concentric to the HPT shaft. 7.1.9 Gas Turbine Support Structures
LM6000 - 60 Hz Classic 6/2008 Page 37 of 156
The LM6000 gas turbine uses three frames to support the LP and HP rotors, the front frame, compressor rear frame and the turbine rear frame. This configuration produces excellent rotor stability and closely controlled blade tip clearance. 7.1.9.1 Front Frame The LM6000 front frame is a major engine structure that provides sup-port for the LPC shaft and the forward end of the HPC shaft. The frame also forms an airflow path between the outlet of the LPC and the inlet of the HPC. The front engine mounts attach to the front frame. The front frame contains the engine “A” sump that incorporates the thrust and radial bearings to support the LPC rotor and a radial bearing which supports the forward end of the HPC rotor. Lubrication oil supply and scavenge lines for the “A” sump are routed inside the front frame struts. The accessory gearbox drive shaft is located in the “A” sump and extends out through the strut located at the six o’clock position. Pads are contained on the frame outer case for mounting of the two High Pressure Compressor inlet temperature sensors. 7.1.9.2 Compressor Rear Frame The compressor rear frame consists of an outer case, 10 struts and the “B-C” sump housing. The outer case supports the combustor and 30 fuel nozzles. The hub supports both the thrust bearing, the radial bearing and in turn, the mid-section of the HP rotor system. 7.1.9.3 Turbine Rear Frame The turbine rear frame supports the rear engine mount and contains the D-E sump. The 14-strut rear frame guides and straightens the exhaust flow for lower pressure drop and greater efficiency. 7.1.10 Accessory Drive System The hydraulic starter, lube and scavenge pump, variable geometry hydraulic pump, and other accessories are mounted on and driven by the accessory gearbox. The accessory gearbox is located below the front HPC casing at the six o'clock position on the LPC bleed air collector and is driven by the transfer gearbox through a short horizontal shaft. The transfer gearbox is driven by the high-pressure rotor system. The gearbox is supported from the LPC bleed air collector.

Simplified Schematic – Ventilation and Combustion Air System
LM6000 - 60 Hz Classic 6/2008 Page 40 of 156
7.4.1 Filtration Specification The LM6000 static barrier filter removes more than 99.9% of all particles 5.0 micron and larger by utilizing a three-stage design.
Engine Combustion Air 230,000 scfm / 6,514 m3/min
Turbine Ventilation Air 60,000 scfm / 1,699 m3/min.
Generator Ventilation Air 45,000 scfm / 1,274 m3/min.
Total Typical Air Flow 355,000 scfm / 9,487 m3/min. 7.4.2 General Arrangement The three-section inlet air filter mounts directly above the turbine enclosure, conserving space and providing compact, low-pressure loss ducting to the turbine inlet. The filtered air is partitioned within the filter house assembly, providing combustion air for the gas turbine and ventilation air for the turbine and generator compartments.
The filter is designed for easy maintenance. A ladder and platform provides access to service doors on each filter section. Lighted internal walkways provide generous working room for replacement and maintenance of the filter elements.
LM6000 - 60 Hz Classic 6/2008 Page 41 of 156
AIR FILTER
Air Inlet Filter Assembly
7.4.3 Filter House Materials
7.4.4 Inlet Screens/Weatherhood
The weather hood provides a deflecting surface to prevent driving rain and snow from entering the filter house. In addition paper, leaves and wind-blown trash are blocked by the inlet screen. This structural component makes up the exterior face of the filter house and is manufactured from carbon steel.
The filter housing is constructed of 3/16 inch / 76 mm (verify units) steel plate. Protective paint is applied to the exterior and interior carbon steel surfaces.
Floors and drain pans downstream of the optional evaporative cooler media or optional inlet air chiller coils are stainless steel to resist corrosion.
LM6000 - 60 Hz Classic 6/2008 Page 42 of 156
7.4.5 Barrier Filter
7.4.6 Clean Air Plenum
7.4.7 Transition Ducts
Combustion air flows through a transition duct from the clean air plenum to the combustion air inlet silencer. Ventilation air flows through transition ducts to the turbine and generator compartment. 7.4.8 Inlet Silencer
The inlet silencer is a low-pressure-drop device located in the combustion air stream before the inlet volute. The silencer attenuates noise from the turbine and helps maintain the unit's low noise level. 7.4.9 Inlet Volute
The inlet volute is stainless steel weldment that directs the combustion air flowing down from the filter and turns it 90° to flow axially into the turbine inlet. Vanes within the volute smooth the airflow and present a balanced air stream to the turbine bellmouth.
The high-efficiency cylindrical barrier filter elements are mounted to the filter face of the inlet plenum and extend into the clean air plenum. The elements have extended surface area, large dirt holding capacity and low-pressure drop. Air flows through the elements from inside to outside keeping dirt safely trapped inside the element. The filter elements are designed specifically for gas turbine protection, and are particularly effective in filtering particles 5 microns or larger.
Air passes through the barrier filters and enters the clean air plenum. This fabricated structure is the center section of the inlet filter assembly and separates ventilation air from combustion air.
LM6000 - 60 Hz Classic 6/2008 Page 43 of 156
7.5 Package Enclosures The package is equipped with a generator and a turbine enclosures plus an optional auxiliary module enclosure is available. The unit enclosures are designed for outdoor installation with wind loads up to 150 mph / 240 km/h and to reduce the average near field noise to 85 dB (A) at 3 ft. / 1.0 m from the enclosure and 5 ft. / 1.5m above grade. Each compartment is provided with access doors and AC lighting. The turbine compartment contains an integral overhead bridge crane to facilitate engine removal. Enclosure walls are a “sandwich” construction filled with insulation blankets of high temperature, sound attenuating material. The inner wall panel is fabricated from perforated 1.21 mm / 18-gauge stainless steel. The outer wall panel is 1.9 mm / 14-gauge cold rolled carbon steel, painted with abrasion resistant, exterior quality epoxy paint. The turbine and generator compartment walls are supported by a structural steel framework that can withstand external wind loading and the internal pressure developed by the fire extinguishing system. External door hinges, latches and mounting hardware are stainless steel or chrome plated. 7.5.1 Enclosure Lighting AC lighting for the interior of the gas turbine and generator compartments is provided. 7.5.2 Enclosure Ventilation System The ventilation system removes heat from the turbine and generator compartments and removes combustible gases in the event of a fuel system failure. Both the turbine compartment and generator compartment are fully ventilated by redundant fans to improve reliability. Ventilation air is filtered to the same quality levels as the gas turbine combustion air.
LM6000 - 60 Hz Classic 6/2008 Page 45 of 156
7.5.2.1 Turbine Compartment Ventilation Ventilation air enters the turbine compartment around the inlet collector. Dual 125 hp / 93 kW exhaust fans (1 running / 1 standby) create an induced-draft airflow of approximately 60,000 scfm / 1,699 m3. 7.5.2.2 Generator Compartment Ventilation
Filtered air is forced into the generator compartment by dual 100 hp / 75 kW forced draft fans (1 running / 1 stand-by) through ducts from the inlet air filter. The 45,000 scfm / 1,270 m3/min. airflow cools the generator and the generator compartment.
The ventilation fans produce a positive pressure in the generator compartment, providing additional isolation from the turbine compartment for gas leak protection purposes. This contributes to classification of the generator compartment as a non-hazardous area. 7.5.3 Noise Control
Lower noise limits can be provided with optional silencing equipment. Noise control will depend on the scope of the equipment supplied, the site plan, and project specific requirements. 7.5.4 Turbine Exhaust The LM6000 exhausts air is extracted axially through a flange located at the end of the turbine enclosure. This provides low restrictions and a direct path into optional, or customer-supplied silencing or heat recovery equipment. 7.6 Baseplate
LM6000 generator sets are mounted on rugged I-beam baseplates to simplify shipping and installation. The basic equipment is supplied with the support structures consisting of a two-piece skid assembly, which is sectioned between the gas turbine and the generator. The full depth, bolted section is designed to provide the full structural properties of the wide flange I-beams. Full depth crossmembers are utilized to provide a rigid design that meets the requirements of IBC 2006 and is therefore suitable for installation in earthquake areas. The baseplate support system is enhanced by the installation of a heavy-duty, welded superstructure which utilizes 6 inch x 6 inch x 3/8 inch wall structural tubing for wall columns and roof beams.
The LM6000 enclosure and air inlet silencer reduce the average near field noise to 85 dB (A) at 3 ft. / 1.0 m from the enclosure and 5 ft / 1.5 m above grade.
LM6000 - 60 Hz Classic 6/2008 Page 46 of 156
Tapered pins between the baseplates simplify field alignment and lifting spools are built into the baseplates providing a convenient structure for transportation.
7.7 Fuel System The LM6000 gas turbine can be configured for gas, liquid or dual fuel operation. The basic gas fuel system is described below. Other configurations are available as options. 7.7.1 Gas Fuel System The gas fuel system contains the following major components. They are mounted in the turbine compartment, adjacent to the engine. • Fuel gas strainer • Fuel gas flow meter • Instrumentation • Primary shutoff valve • Fuel metering valve • Secondary shutoff valve • Fuel gas manifold • Shipped loose manual shut-off valve 7.7.1.1 Gas Fuel Flow Gas fuel must be supplied to the package baseplate connection at 675 +30/-20 psig / 4,053 – 4,962 kPag. Please see Section 14 for applicable fuel specification. Lower fuel supply pressure requirements for base load operation may be possible in certain circumstances.
A customer supplied pressure regulator, pressure relief valve and GE supplied manually operated shut-off valve should be installed in the customer fuel supply system outside of main unit.

7.7.1.2 Pressure and Temperature Monitoring Pressure transmitters monitor the fuel supply pressure up stream and downstream of the fuel metering valve and forward the data to the fuel control and sequencer system. A platinum, dual element temperature RTD monitors fuel supply temperature and forwards the data to the fuel control and sequencer system. 7.7.1.3 Fuel Shutoff Valves and Safety Venting Fuel shutoff valves manage gas flow to the combustor. Solenoid piloted fuel shutoff valves are quick-closure valve assemblies located upstream and downstream of the gas fuel metering valve. These fail-close valves are either fully open to allow fuel flow or fully closed to prevent fuel flow.
During startup, the shutoff valves are opened and fuel flow to the gas manifold is metered by the gas fuel metering valve. During shutdown, when the shutoff valves are closed, a solenoid-operated vent valve opens to vent the fuel supply line between shutoff valves to a safe area. A gas fuel drain valve opens during certain shutdown conditions to purge the gas manifold and the engine.
LM6000 - 60 Hz Classic 6/2008 Page 48 of 156
7.7.1.4 Fuel-Metering Valve
The electronically controlled fuel valve provides accurate, non-pulsating fuel flow to the turbine during starting, steady-state operation and dynamic load changes. Low fuel gas pressure starting is possible, using the electrical output of the LM6000 to power a fuel gas compressor. The LM6000 can start on a minimum 200 psig / 1,380 kPag fuel gas pressure. At this pressure the LM6000 produces enough electrical power to start a fuel gas compressor. The compressor then builds the fuel gas pressure up for full power output.
This “bootstrap” starting simplifies gas utility requirements and eliminates high electrical “demand charges” for starting the gas compressor motors. Contact GE for your specific application. 7.8 Independent Lube Oil Systems
The LM6000 gas turbine is lubricated with synthetic lube oil (SLO) while a separate mineral lube oil (MLO) system lubricates the generator.
Dual shell and tube coolers with valves for on-line changeover are used to cool both turbine and generator lube oil. The SLO & MLO coolers are mounted on the auxiliary module.
Lube oil piping, fittings and reservoirs are Type 304 stainless steel and valves have stainless steel trim.
7.8.1 Gas Turbine Lube Oil System The gas turbine lube oil system has two lube oil circuits:
Supply System - Provides filtered, cool oil to the turbine bearings.
Scavenge System - Recovers (scavenges) the lube oil from the bearing drain sumps. It also filters and cools the oil and returns it to the reservoir.
These two circuits cool, lubricate and protect the turbine. The turbine supply system contains the following major components: • SLO reservoir • Supply pump • Supply filter The scavenge system contains the following major components:
LM6000 - 60 Hz Classic 6/2008 Page 49 of 156
• Scavenge filter/5-element scavenge pump • Duplex shell and tube water / oil or fin fan air/oil heat exchanger (optional) • Air/oil separator system

Simplified Schematic – Turbine Lube Oil System
LM6000 - 60 Hz Classic 6/2008 Page 50 of 156
7.8.1.1 Turbine Lube Oil Supply Description
Approximately 130 U.S. gallons / 492 l of synthetic lube oil are stored in the 150 U.S. gallon / 568 l capacity stainless steel reservoir mounted on the auxiliary module. The reservoir is fitted with a low-level alarm switch, a level gauge, a level transmitter, a filler connection, and a demister/flame arrestor. The reservoir also includes a thermostatically controlled heater and a lube oil temperature transmitter.
A positive displacement lube oil pump, mounted on the gas turbine accessory drive gearbox, takes suction from the lube oil reservoir. The pump discharge is filtered by a duplex, 6 micron (absolute), full-flow filter located on the auxiliary module. Filter elements can be changed while the turbine is running.
Pressure transmitters and temperature RTDs monitor lube oil supply with readout, alarm and shutdown at the turbine control panel. Chip detectors in the A and B sumps and in the common scavenge return provide alarms if metal chips are detected in the lube oil. A differential pressure transmitter senses filter differential pressure and warns the operator of dirty filter conditions.
7.8.1.2 Turbine Lube Oil Scavenge Description
Oil flows through the turbine bearings and accumulates in the bearing sumps. A 5-element scavenge pump is connected to a low point drain in each sump. Whenever the engine is turning the scavenge pump is working to remove oil from the sump drains.
The scavenge pump discharge flows through a 6 micron (absolute) duplex filter, then is cooled by a shell and tube cooler, (1 running / 1 standby) and then returns the oil to the reservoir.
A temperature RTD on each scavenge line measures temperature, with readout, alarm and shutdown at the turbine control panel. A check valve on the pump discharge prevents siphoning of oil back into the engine during shutdown.
Each bearing sump is vented by the air/oil separator system, consisting of a pre-separator, air-to-oil cooler, and a final separator. Recovered oil drains back to the reservoir to reduce emissions and oil consumption.
A shell and tube cooler (1 running / 1 standby) rejects 600,000 Btu/hr / 633,100 kJ/hr from the turbine lube oil circuit. A thermostatic valve regulates the amount of hot oil that bypasses the cooler.
The lube oil supply passes through an anti-siphon check valve and is distributed to the bearing chambers, where oil is sprayed onto each engine bearing.
LM6000 - 60 Hz Classic 6/2008 Page 51 of 156
7.8.2 Generator Lube Oil System
The generator lubrication system provides approximately 46 gpm / 174 lpm of cooled and filtered mineral oil to the generator bearings. The generator lube oil reservoir, pumps and duplex filters and coolers are located near the rear of the generator and lube oil filters may be changed while the unit is operating. Filters have stainless steel plates. Valves are carbon steel bodies with stainless steel trim. The generator lube oil system has two lube oil circuits:
Supply System – Provides cool, filtered oil to the generator bearings. The supply system contains the following major components: • MLO reservoir • AC pump • Generator driven mechanical pump • Four-element jacking oil pump • Duplex shell and tube heat exchanger • Duplex filter Return System - Recovers the lube oil from the bearing drain sumps and returns it to the reservoir.
These two circuits cool, lubricate and protect the generator.
LM6000 - 60 Hz Classic 6/2008 Page 52 of 156
Simplified Schematic – Generator Lube Oil System (Supply Flow)
7.8.2.1 Generator Lube Oil Supply Description
The 60 Hz generator lubrication system provides approximately 174 Lpm/46 gpm of cooled and filtered oil to the generator bearings
The generator/gearbox lube oil reservoir, pumps and filters are located on a separate lube oil module. The lube oil filters may be changed while the unit is operating.
The simplex shell & tube coolers serving the generator lube oil system are also located on the lube oil module. Filters have stainless steel plates. Valves have stainless steel trim.
The stainless steel reservoir includes a sight level gauge, fill connection and drain valve. A switch provides a low-level alarm at the unit control panel. An immersion heater turns on at 32ºC falling temperature keeping the oil heated to prevent condensation when the unit is stopped.
The 60 Hz lube system has three pumps mounted on the reservoir: o Main Pump – 1,250 Lpm/330 gpm with a 37.3 kW AC motor
LM6000 - 60 Hz Classic 6/2008 Page 53 of 156
o Stand By Pump – 1,250 Lpm/330 gpm, with a 37.3 kW AC motor o Emergency Pump – 550 Lpm/145 gpm with a 12 kW DC motor o The reservoir assembly includes: o Duplex 100% filters o Duplex shell and tube heat exchangers sized to reject 2,943.8 MJ/hr o Oil-mist heat exchanger and motor-driven oil demister Rundown tanks provide additional protection if the AC lube pumps should fail, or if AC power is lost. A DC pump provides coastdown protection. The oil flows through the orifice and into the bearings and forms a film that cools and lubricates the journal. Pressure switches at the bearing supply header provide low pressure alarm and shutdown signals to the unit control panel. If the supply pressure drops, a low lube oil pressure switch automatically starts the auxiliary lube oil pump. An annunciator alarm indicates that the auxiliary pump is running. If the lube oil pressure falls to a lower level, the turbine generator set shuts down. The primary and auxiliary lube oil pumps can each supply 100% of the generator lube oil requirements. Each pump is equipped with a pressure relief valve piped to the reservoir. Lube oil pressure at the supply header is controlled by a pressure-regulating valve, which bypasses excessive oil flow to the reservoir. Duplex coolers are provided to reject 198.1 MJ/hr from the generator lube oil circuit. The amount of hot oil that bypasses the cooler is regulated by a thermostatic valve. The duplex generator / gearbox lube oil filters (6 micron absolute) are mounted on the lube oil module. Filters may be replaced during operation by switching the manual transfer valve. A pressure switch senses high filter differential pressure and provides alarm at 20 psid/138 kPa.

Simplified Schematic – Generator Lube Oil System (Bearing Lubrication)
7.8.2.2 Generator Lube Oil Return Description
Each bearing has a gravity drain and sight glass to visually verify oil flow. A dual element RTD is embedded in each generator bearing to measure the actual metal temperature. These RTDs are continuously monitored at the unit control panel and provide alarm and trip signals at 183°F/91.6°C and 194°F/95ºC, respectively. The gearbox has a turning gear to rotate the shaft. The gearbox bearing RTDs alarm and trip at 225°F/107ºC and 241°F/116ºC respectively.
For starting and water wash cycles, we lift the generator rotor off the bearing seats with a film of high-pressure oil from a small “jacking oil” pump. The oil film reduces bearing friction and helps the rotor “break away” and begin turning.
LM6000 - 60 Hz Classic 6/2008 Page 55 of 156
7.8.3 Customer Cooling Water Requirements Customer provides continuous water to the lube oil cooler flange connections. Approximate cooling water requirements are 190 gpm at 95 °F / 719 lpm at 35 °C. Maximum water pressure is 100 psig / 689 kPag. Total heat rejection for turbine and generator is 787,800 Btu/hr / 831,200 kJ/hr. 7.9 Starting System The LM6000 turbine is started by an electro-hydraulic system, including an electric motor, a pump, a hydraulic starter motor, and other equipment described below. The starter rotates the LM6000 high-pressure compressor shaft for purging, cool down, engine starting and water wash sequences. The hydraulic start system consists of a hydraulic starting motor / clutch mounted on the turbine accessory gearbox, the following equipment mounted on the auxiliary module: • 200 HP / 150 kW electric starting pump motor • Variable displacement hydraulic pump • 40 gal. / 151 l hydraulic reservoir • Air/oil cooler • Low pressure return filter and case drain return filter
LM6000 - 60 Hz Classic 6/2008 Page 56 of 156
Simplified Schematic – Hydraulic Start System
7.9.1 Hydraulic Start System Flow
The hydraulic circuit is a closed loop design with a 40-gallon / 151 L reservoir. The system requires an initial fill of approximately 35 gallons / 132 l of ISO VG 46 premium, anti-wear petroleum-based hydraulic fluid.
During each start cycle a charge-pump portion of the main pump draws fluid from the reservoir to prime the system and supply control oil. Controls modulate the main pump flow from zero to approximately 55 gpm / 208 Lpm during the starting cycle. This permits accurate control of gas generator speed for purging, ignition and acceleration. The starter pump increases the hydraulic fluid pressure and delivers the pressurized fluid to the hydraulic starter motor. A portion of the return fluid from the starter motor is routed back to the starter pump. Before reaching the main hydraulic pump on the auxiliary skid, the oil is filtered through a low-pressure, return filter. Low-pressure hydraulic fluid from the starter motor case is routed off the main skid to the auxiliary skid. On the auxiliary skid, the hydraulic fluid flows through a case drain return filter and a air to oil heat exchanger before returning to the reservoir.
7.9.2 Starting System Operation
To start the gas turbine, the hydraulic motor must:
• Rotate the gas generator to purge the engine • Accelerate the gas generator to ignition speed • Continue acceleration to self-sustaining speed The starter accelerates the gas generator to 2,300 rpm and cranks for two minutes in typical simple cycle applications. This forces purging air through the gas turbine and exhaust stack to remove hydrocarbons that may have accumulated during the prior shutdown.
Air-flow during the purge cycle is approximately 7842 scfm / 12,600 Nm3/h / 10 lbs/sec. After the purge cycle, the gas generator is slowed to 1700 rpm for light off. Fuel is initiated, igniters are actuated, and the turbine starts. Then the starter and the combustion accelerate the gas generator to 4500 rpm where the starter disengages automatically. The gas generator continues to accelerate until it reaches idle speed. The turbine is now self-sustaining. Overall start time varies with stack height; also units with heat recovery steam generators will require a longer purge cycle, typically 15 to 30 minutes.
LM6000 - 60 Hz Classic 6/2008 Page 57 of 156
However, the typical LM6000 in simple cycle application can reach full power from a cold start in 10 minutes. See Section 5 for 10-minute start cycle curve.
7.10 Water Wash System
All gas turbines demonstrate lower levels of performance if the airfoils are not in a clean condition. An integral soak wash system is provided for on/offline cleaning. See Section 14 for compressor cleaning water/detergent specifications. GE Energy LM6000 units include a unit mounted on-line cleaning system to remove deposits from the compressor airfoils. The off-line or “crank-soak” water wash system is for thorough removal of built-up deposits. This system requires the turbine to be off-line for a short time. The on-line cleaning system is used to remove deposits while the turbine is running. This system extends the intervals between crank-soak cleanings and reduces downtime.
Simplified Schematic – Water Wash System
7.10.1 Water Wash Equipment
Both on-line and off-line spray nozzles are mounted on the Inlet Air Volute on the main baseplate. The remaining water wash equipment below is mounted on the auxiliary module:
LM6000 - 60 Hz Classic 6/2008 Page 58 of 156
• 100 gallon / 379 l stainless steel reservoir • Manual water and chemical supply valves • Solenoid valves to sequence water wash and purging • Motor-driven pressurizing pump • Electric heater in tank In-line water filter 7.10.2 Cleaning Solution Specifications
7.10.3 Water Quality Standards
Please see GE Specification MID-TD-0000-4 for water wash criteria. 7.10.4 Interface Requirements
Customer supplies a source of hot water and instrument/compressed air to purge lines at GE Energy flange connections on auxiliary module. Interconnecting piping and hoses to the permanently mounted turbine spray manifold is provided.
7.11 Fire Protection System
The LM6000 turbine generator set includes controls and sensors to detect fire, unsafe temperatures or explosive atmospheres in the equipment enclosure. The system releases CO2 if fire is detected.
The package enclosure is designed to reduce the hazard of fire and explosion. A wall separates the turbine and generator compartments to provide isolation. Ventilation systems, with redundant fans, create a positive pressure in the generator compartment and a negative pressure in the turbine compartment. This maintains separation and forces hydrocarbons away from the generator. The enclosure is protected by gas detectors, thermal detectors, optical flame detectors and a CO2 extinguishing system conforming to NFPA 12.
Cleaning agents conforming to GE Specification MID-TD-0000-5 are recommended for washing the gas generator section of the engine. The solvents are mixed within the reservoir and sprayed into the turbine inlet. Water is then sprayed in the inlet to rinse the turbine.
A water/anti-freeze mixture must be used for dilution and rinsing in ambient temperatures of 50 °F / 10 °C, or below.
LM6000 - 60 Hz Classic 6/2008 Page 59 of 156
Fire and Gas Protection System
7.11.1 Gas Detectors
Four hydrocarbon gas detectors and two infrared gas detectors are provided. Two hydrocarbon gas detectors are located in the turbine compartment. One hydrocarbon gas detector is located below the turbine. A fourth detector is located in the front of the generator compartment. Two infrared gas detectors are located in the turbine enclosure near the ventilation exhaust duct. If the gas detectors in the turbine or generator compartments sense a gas concentration of 15% LEL, a warning is initiated. If a sensor detects a gas concentration of 25% lower explosion limit, an emergency shutdown is initiated. If an infrared sensor senses a gas concentration of 5% LEL, a warning is initiated. If a sensor detects a gas concentration of 10% LEL, an emergency shutdown is initiated.
LM6000 - 60 Hz Classic 6/2008 Page 60 of 156
7.11.2 Optical Flame Detectors
There are three IR/Optical flame detectors mounted in the turbine enclosure and three mounted in the generator enclosure. A flame indication by a turbine enclosure sensor causes an emergency shutdown and release of CO2.
7.11.3 Thermal Detectors
The turbine enclosure temperature is monitored by two thermal spot detectors, initiating a shutdown at 450 °F / 232.2 °C. The generator enclosure temperature is monitored by two thermal spot detectors, initiating a shutdown at 225 °F / 107.2 °C.
In addition to alarm and shutdown functions, the thermal spot detectors provide enclosure temperature signals for the turbine control panel HMI. The spot temperature detectors are bi-metallic and respond to both temperature and rate-of-rise. They cause a unit shutdown and release of the CO2 when tripped.
7.11.4 Manual System Trip
Three manual trip stations are located on the main enclosure; one on each side near the center of the package, and the third at the exciter end of the generator.
7.11.5 CO2 Extinguishing System
The system components include:
• Main CO2 storage cylinders • Reserve CO2 storage cylinders • Valves, piping and wiring
The pressurized CO2 bottles are stored on a rack that includes manifolds, controls, valves and a weigh scale. The reserve cylinders are an “automatic backup,” and are released, if the detectors still indicate a hazard, 90 seconds after release of the main cylinders.
GE Energy provides piping within the main enclosure from the pressure connection to the nozzles in the turbine and generator compartment. Release of the CO2 is controlled by the fire system control panel or by a manual valve at the unit. Signals from the equipment-mounted sensors are monitored by solid-state modules in the control panel. The panel-mounted unit includes logic, memory and output functions.
7.11.6 Dedicated Power Supply
LM6000 - 60 Hz Classic 6/2008 Page 61 of 156
GE Energy furnishes a dedicated 24 VDC battery system with charger, to power the fire and gas protection and control system. This battery system conforms to NFPA 12 requirements.
7.11.7 Control System
A solid-state monitor mounted in the Turbine Control Panel compares the signal from each sensor to alarm and shutdown setpoints. Meters provide a read out of each gas detector signal. Any alarm signal sounds an alarm at the control panel and in the turbine enclosure.
Any shutdown signal from a gas detector, optical detector, thermal detector, or manual station closes a contact and causes an emergency shutdown of the unit.
7.11.8 Defective Sensor Protection
Each sensor is connected with closed loop circuitry to verify its readiness. Should the sensor or its wiring become defective, a "fault" condition is indicated on the control panel. 7.11.9 CO2 Release Logic
When a shutdown signal is received the control system turns off the ventilation fans and sounds an alarm horn at the panel and both inside and outside of the turbine enclosure. After a time delay, CO2 is released into the generator and turbine compartments.
A CO2 concentration sufficient to extinguish flames is reached in approximately 30 seconds. If the primary cylinders should fail to discharge within four seconds, the reserve cylinders are discharged.
If flames are still detected 90 seconds after the primary CO2 cylinders have been discharged, the reserve cylinders are discharged.

The LM6000 generator set, with optional modifications, can operate as a synchronous condenser when an electrical grid needs VARs to improve the Power Factor (PF). For this option, GE adds a synchronous clutch, in an enclosure, between the gas turbine and generator. Modifications are also added to the protective relay system and the voltage regulator. These additions allow the unit to operate as follows: • The gas turbine is started and brought up to speed
• The generator is synchronized to the grid
• The operator selects Synchronous Condenser operation with a switch on the Turbine Control Panel
• The gas turbine begins a normal shutdown
• As the turbine slows down, the Synchronous Clutch disengages
• The generator remains running, and is now operating as a motor, powered by the grid.
• The operator can now export or import VARs by raising or lowering the voltage set point on the Voltage Regulator (within limits designed to protect the equipment).
8.2.2 Totally Enclosed Water-Cooled Generator
GE Energy furnishes a Totally Enclosed Water-to-Air Cooled (TEWAC) generator for customers who prefer water-cooling. Customer must supply approximately 571 gpm / 2161 lpm of treated water at 85ºF / 29ºC, or cooler, at 100 psig / 690 kPa. If water is to be recycled, customer must supply a cooling loop to reject approximately 2 million BTU/hr / 2110 MJ/hr.
8.2.3 Power System Stabilizer The GE EX2100 digital power system stabilizer integrates supplementary control signals to the generator’s voltage regulator to control power fluctuations and to help improve the stability of the power system.
8.2.4 Left-Hand Piping Connections
In the standard LM6000 configuration, the customer’s piping connections are on the right side, as viewed from the exciter. As an option, the unit can be built with the piping
LM6000 - 60 Hz Classic 6/2008 Page 64 of 156
connections on the left side. The turbine removal area is located on the side opposite of the piping connections.
8.2.5 Left-Hand Cubicles / Right Hand Cubicles In the standard LM6000 configuration the generator line side cubicle is on the right side as viewed from the exciter. The neutral cubicle is on the left side. As an option the unit can be configured with the line side cubicle on the left side and the neutral cubicle on the right side.
8.2.6 Liquid Fuel System
The LM6000 can be equipped to operate using liquid fuel instead of natural gas. Typical liquid fuels include DF1, DF2, JP4 or kerosene. Customer must supply liquid fuel at 20-50 psig /138-345 kPag and at least 20ºF / 11ºC above the “wax point” temperature (normally 35ºF / 1.6ºC). Maximum fuel temperature is 150ºF / 65ºC. Customer supplied fuel must be clean, filtered and meet required fuel specifications. See Section 14.
8.2.7 Dual Fuel System Complete fuel systems for two different fuels, including piping, valves and controls. Fuels can be: • Natural gas with liquid fuel • Two gaseous fuels • Two liquid fuels Manual or automatic transfer to backup fuel requires a reduction in power. However, if full load fuel transfer is required, an optional cooler is provided to cool the air stream used to purge the fuel nozzles during transfer. This cooler requires a continuous water flow of 20gpm / 76 lpm at 65psi / 448 kPag, 95 °F / 35 °C max.
8.2.8 Water Injection System
The water injection system contains the following major components. They are mounted on the water filter skid, water injection pump skid and main skid. • Duplex low pressure filter • Water injection pumps (primary and standby) • Flow transmitter • Flow metering valve To control the amount of oxides of nitrogen (NOx) emitted by the gas turbine engine during normal operation, demineralized water is injected into the combustor section of the gas turbine through the water injection manifold. Demineralized water from a customer source is pressurized by the selected water injection pump and plumbed into the main skid.
LM6000 - 60 Hz Classic 6/2008 Page 65 of 156
8.2.8.1 Water Filter and Water Injection Pump Equipment
Demineralized water supplied to the auxiliary skid must meet GE quality requirements MID-TD-0000-3 – See Section 14. Demineralized water flows through the duplex water injection filter, where water is filtered to 10 microns before being pressurized by the centrifugal water injection pump. Downstream of the filter, demineralized water flow branches to provide water to either water injection pump. Two identical water injection pumps are provided in the system (primary and standby). If there is a pump failure, the operator, after investigating the cause of the failure to verify the problem is not related to water supply or piping problems, can then select the standby pump from the human machine interface (HMI) screen. The standby pump becomes the primary pump and the operator can enable the water injection system. Necessary pressure and temperature instrumentation allow remote monitoring of the water injection system on the auxiliary skid.
8.2.8.2 Main Skid
Water flow enters the main skid piping at an operating pressure of 800-950 psig / 5,517 – 6,550 kPag for gas fuel operation an 1200-1320 psig / 8274-9101 kPag for liquid fuel. An electrically actuated water injection flow-metering valve modulates de-mineralized water flow to the engine manifold and to the water return in response to data received and processed by the control system. Downstream of the metering valve, de-mineralized water flows through a solenoid shutoff valve which opens when the control system commands the water injection system active and closes when the GTG set is stopped or the water injection system is commanded off. A flow transmitter sends a 4–20 mA proportional signal to the digital control system providing flow data used to totalize water use and calculate the water-to-fuel ratio. While the system is not in operation, any water in the manifold piping drains from the system through a manifold drain solenoid valve. Pressure in the downstream piping blows any residual water out of the system. The gas fuel purge flow from the engine manifold assists in clearing residual water from the system piping. Necessary pressure and temperature instrumentation allow remote monitoring of the water injection system on the main skid. All piping is stainless steel, and the valves are trimmed with stainless steel.
8.2.9 SPRINT® Power Boost System
SPRINT® Is A Spray Intercooling System That: • Reduces combustion air temperature
• Boosts turbine output power
LM6000 - 60 Hz Classic 6/2008 Page 66 of 156
• Increases exhaust energy by injecting fine water droplets into the inlet and interstage air stream
The SPRINT power performance curves are provided in chapter 5. Customer supplies demineralized water at 30 gpm / 114 lpm, and 275 psig / 1896 kPag and 150 ºF / 66 ºC nominal. Consult GE Energy for details.
8.2.10 Evaporative Cooling Evaporative cooling lowers inlet temperature to the gas turbine for added power. This option is recommended when high dry bulb temperatures are common, with low/medium ambient humidity. This system is designed for recirculation of evaporative cooling water from a sump in the bottom of the inlet air filter. This option includes recirculation pump, conductivity probe, blowdown and make-up valves, piping and wiring. Customer must supply filtered, potable water to a flanged connection on the filter house and must dispose of waste water from the blowdown valve. Flow rates will vary based on blowdown.
8.2.11 Inlet Air Chiller Coil To increase the output of the LM6000 during hot weather, GE Energy installs a chiller coil
upstream of the static filter. A water/glycol mixture is circulated through the coil to lower inlet air temperature and improve turbine performance. The chiller system includes the following:
• High performance cooling coils
• Can be offered separately or in conjunction with a mechanical chiller module with pumps, motors and controls for water/glycol circulation of 3,300 gpm / 12,493 lpm.
LM6000 - 60 Hz Classic 6/2008 Page 67 of 156
8.2.12 Inlet Air Anti-Ice Coil – Exhaust Heat Recovery Unit (Primary Option)
GE Energy recommends an anti-ice system for safe operating during icing conditions and provides several anti-ice options. With this option, exhaust heat is utilized to provide anti-ice heating of the inlet air and can be used with the included anti-ice coils or with chilling coils provided separately. The three major components of this system are as follows: Waste Heat Skid The waste heat skid utilizes gas turbine exhaust gas to fluid heat exchanger. Exhaust gas from the gas turbine stack is extracted and flows through the plate fin and tube, all stainless steel heat exchanger. Exhaust gases then flow through a blower which boosts the exhaust gas pressure and returns the exhaust gas back to the stack. A flow control damper is provided at the blower discharge to control the air temperature rise across the inlet air going to the gas turbine. A water- glycol mixture is heated in the gas-to-fluid heat exchanger with a design duty of 4 mm BTU/hr. At ambient conditions when the anti-ice system is not required, dampers at the inlet to the waste heat recovery unit (WHRU) and outlet of the blower are closed. A purge blower is activated to inject air to prevent overheating the fluid. A temperature alarm set at 200° F / 93° C is also provided to start the fluid pump if the purge blower is inoperative or cannot provide sufficient purge air to prevent overheating. Fluid Pump Skid The heated fluid is pumped through an anti-ice coil located upstream of the static filter to heat the inlet air 15º F / 8.3º C. The pump skid is designed to circulate 300 gpm / 1136 lpm of fluid using duplex (2 x 100%) 7.5 kW / 10 hp pumps. The closed system includes a pressurized expansion tank and the entire anti-ice system contains approximately 350 gallons of fluid. Under normal conditions no make-up or discharge is required. A low flow switch is provided to shut down the pump and blower skid if flow disruption is detected and an alarm on the Turbine Control Panel alerts the operator to this condition. Please consult GE Energy sales for details. Anti-Ice Heating Coils
LM6000 - 60 Hz Classic 6/2008 Page 68 of 156
Anti-ice coils are provided and installed in the air filter assembly. Coils are piped to a common manifold with customer connections on each side of the main skid. If chilling coils are present they will be utilized for both chilling and anti-icing duty.

8.2.13 Inlet Air Anti-Ice Coil With this option, GE Energy installs an anti-ice coil upstream of the static filter. The customer circulates a heated water-glycol mixture through the coil to heat the inlet air 15 ºF / 8.3 ºC. Check with GE Energy for details.
8.2.14 Inlet Air Anti-Icing - Ventilation Recircula tion With this option, GE Energy recirculates warm turbine room ventilation air back to the inlet air filter in order to keep ice from forming on the filter. Check with GE Energy for details.
8.2.15 Pulse Filter (Self Cleaning) GE Energy uses a pre-engineered, self-cleaning filter option for job sites with special needs such as dust, pulp and paper fiber and snow. Self-cleaning filter elements are provided for combustion and ventilation air paths. The filter house mounts above the turbine enclosure and is supported with legs. Downward air-flow provides filtered air for combustion and ventilation. This compact filter design is easily installed in the field, and it eliminates customer supplied ducting. The filter system includes a stainless steel inlet silencer and a ladder and platform for inspection and servicing of the filter.
LM6000 - 60 Hz Classic 6/2008 Page 70 of 156

Extent of scope will depend on the scope of equipment, Site Plan and Project Special Requirement. Start-up and Shutdown modes may exceed these levels. 8.2.25 Remote Monitoring and Diagnostics Service Monitoring and Diagnostics Service helps aeroderivative turbine plant operators improve availability, reliability, operating performance, and maintenance effectiveness. Monitoring of key parameters by engine experts may lead to early warning of equipment problems and avoidance of expensive secondary damage. Diagnostic programs seek out emerging trends, prompting proactive intervention to avoid forced outages and extended downtime. The ability for GE engineers to view real-time operation accelerates troubleshooting and sometimes removes the need for service personnel to visit the plant. 8.2.25.1 System Overview

10. Generator, Exciter and Voltage Regulator
10.1 Generator Design
The generator is a synchronous, two-pole, cylindrical rotor machine. It has open-air cooling and a brushless excitation system with permanent magnet generator. The rotor is supported by two (2) split sleeve bearings lubricated by a pressurized mineral oil system.
The generator has a design life of 30 years. The weatherproof acoustic enclosure reduces average noise levels to 85 dB(A) at three feet (1.0m) from unit and five feet (1.5m) above grade.
The generator is conservatively sized, with capacity to spare. The stator, rotor and exciter have Class F insulation, and the generator can absorb all of the turbine's output power without exceeding Class B temperature rises.
The generator can also supply the following overload or fault currents without measurable loss of life:
• 110% of normal current for 2 hours out of every 24 hours • 130% of normal current for one minute • 300% of normal current into a 3-phase fault for 10 seconds
LM6000 - 60 Hz Classic 6/2008 Page 87 of 156
10.2 Generator Codes And Standards
The generator is designed to meet codes and standards applicable to most areas of the world. The primary standards include ANSI C50.14 for 60 Hz. Other ANSI, IEE, IEC and NEMA standards also apply.
10.3 Stator Design
10.3.1 Stator Frame
10.3.2 Stator Core
The core is made of segmental laminations of low-loss, high permeability, high silicon content electrical steel, carefully deburred and coated with insulating varnish.
To ensure uniformity, the core is hydraulically pressed at pre-determined stages during the building operation, and the finished core is clamped between heavy steel end plates. The core is subjected to a magnetizing test of the windings to check for the soundness of inter-laminar insulation and adequate tightness.
10.3.3 Stator Winding
The stator is made of pre-insulated half-coils assembled into a two layer diamond array. Eddy current losses are minimized by dividing each conductor into smaller laminations. The laminations are insulated from each other by a resin-impregnated woven glass braid and are transposed to minimize circulating currents.
10.3.4 Insulation System
The insulation system is based on a resin-rich mica glass tape that produces a high performance insulation system capable of continuous operation at temperatures up to 311°F / 155°C (Class F).
The stator frame is fabricated from mild steel plate to form a rigid structure. The stator is equipped with substantial mounting pads with boltholes to secure the generator to the I-beam baseplate.
LM6000 - 60 Hz Classic 6/2008 Page 88 of 156
The insulation possesses high dielectric strength, low internal loss and meets all current specifications. The resin system is thermo-setting, so that the resulting insulated coil sides are dimensionally stable. This resin insulation is highly resistant to most common electrical machine contaminants, such as hydrocarbons, acids, alkalis and tropical molds.
10.3.5 Coil Manufacture
The insulated copper laminations are cut to length, stacked together and the coil ends are formed into shape on a fixture. The laminations are then clamped tightly together, taped with an initial layer of tape and hot pressed to consolidate the conductor stack. Following this, the main insulation is applied and pressed to size. The amount of the compression is carefully controlled to ensure correct resin flow and produce consistent void-free insulation.
Each finished half-coil is subjected to dimensional checks to ensure a correct fit in the stator slot, and special tapes are added to the inner and outer coil surfaces to prevent corona discharge.
10.3.6 Coil Winding and Connections
The half-coils are placed in the stator slots in two layers and wedged securely in position by synthetic resin bonded wedges prior to connection of the endwinding.
In order to withstand the forces resulting from an accidental short circuit, the endwinding is securely braced to insulated brackets mounted on the stator frame.
Spacer blocks are fitted between adjacent coil sides to produce a strong, resilient, composite structure. Finally, the completed stator is "baked" in an oven to fully cure the insulation. Resistance Temperature Detectors (RTD) are embedded in the windings at selected points, and anti-condensation heaters are fitted into the stator frame. To ensure electrical performance, the individual coils and the completed windings are given high-voltage tests.
LM6000 - 60 Hz Classic 6/2008 Page 89 of 156
10.4 Cylindrical Rotor
The cylindrical rotor is manufactured from an integral forging of vacuum poured nickel-chromium-molybdenum alloy steel. The resulting forging is thermally stable, uniform in composition, and has excellent tensile and mechanical properties. As assembly proceeds, slots are machined in the rotor surface, and insulated coils of high-conductivity silver-copper strip are pressed into the slots. Then damper windings and wedges are added. Finally, end caps of non-magnetic manganese chromium steel are shrink-fitted to the ends of the rotor body. The rotor is then balanced dynamically and tested at 120% of normal speed for two minutes. Following high speed testing, the rotor is given a series of high voltage tests to prove the integrity of the insulation system.
10.5 Bearings
The main bearings are conventional, white metal lined, hydrodynamic cylindrical bearings, split on the horizontal centerline for ease of inspection and removal. The two halves are bolted and dowelled together.
Oil is supplied under pressure to the bearings with flow controlled by an orifice in the supply line. Drain oil collects in the bottom of the bearing housing and returns to the generator lube oil reservoir by gravity flow. The generator bearings are end frame mounted on specially stiffened and reinforced stator frames. A detachable solid ribbed steel plate, split on the bearing horizontal centerline, supports the lower half bearing housing. Pressurized air from the downstream side of the generator fans is used to seal the lubricating oil in the bearings. RTDs in the bearing metal and in the oil drain lines provide bearing temperature sensing.
LM6000 - 60 Hz Classic 6/2008 Page 90 of 156
10.6 Ventilation Systems
Internal Air Circuit The generator is cooled by air forced through ducts in the stator and rotor by two axial fans mounted on the rotor shaft. The cooling air is supplied to the generator from the inlet air filter.
10.7 Brushless Excitation System
The generator is equipped with a low maintenance brushless excitation system consisting of:
• Three phase rotating armature • Three phase rotating rectifier • Rotating permanent magnet generator (PMG) • Exciter field • GE EX2100 automatic digital voltage regulator located in the
turbine control panel • Provisions for a optional Key Phasor
10.8 Voltage Regulator
The generator is furnished with a GE EX2100 microprocessor controlled voltage regulator system. The voltage regulator is rack-mounted in the turbine control panel and maintains generator output voltage within ±0.5% under steady state operating conditions. The voltage regulator utilizes single phase sensing circuitry and includes:
• Diode failure alarm • Flux limiter • Over-excitation limiter • Under excitation limiter • Auto follower & null balance • Auto transfer to manual control • Volts per Hz control
The shaft-mounted PMG powers the voltage regulator and excitation system.
LM6000 - 60 Hz Classic 6/2008 Page 91 of 156
The voltage regulator can be adjusted manually or by remote signals to:
• Raise/lower voltage • Raise/lower VARs or power factor (manual only)
10.9 Generator Accessories
10.9.1 Stator Temperature Detectors
Six duplex temperature detectors (two per phase) are embedded in the stator windings. The detectors are 100 ohm at 0°C platinum type RTDs.
10.9.2 Space Heaters
Space heaters are located inside the generator to prevent condensation of moisture when the generator is not operating. The space heaters are suitable for operation on three-phase, 480 VAC power, 60 Hz. Automatic ON/OFF control for the space heater is provided by the unit control panel that controls a contactor in the motor control center.
10.9.3 Vibration Detectors
Two vibration detectors are mounted 90° apart at each radial bearing (Total 4). The proximeters and cables are wired to the Main Generator Terminal Box (MGTB) in the generator compartment. Monitoring equipment is provided in the unit control panel.
10.9.4 Ground Fault Monitoring
This control system provides continuous electronic monitoring of the generator rotor winding and its connections. Indication of a ground fault is shown on the unit control panel.

LM6000 - 60 Hz Classic 6/2008 Page 95 of 156
The turbine control panel (TCP) houses a majority of the control system equipment. From the TCP, an operator can initiate the turbine-generator’s electronic control system to perform automatic startup, fuel management, load assumption, and system operation. Critical parameters are constantly monitored and alarms or shutdowns are initiated automatically, as appropriate, for out-of-tolerance conditions.
Automatic fuel control and turbine sequencing are controlled by the logic control system software and hardware. Also, an operator or anyone on site can initiate, as necessary, a manual emergency shutdown at any time.
12.1.1 Human Machine Interface (HMI) The HMI displays turbine operation data and mimic screens. It includes operator input and function pushbuttons. 12.1.2 Vibration Monitoring The Bently Nevada 3500 vibration monitoring system monitors the vibration levels at critical points along the turbine generator package. 12.1.3 Generator Monitoring The Satec SA296 simplifies the monitoring and management of generator electrical conditions and output. In addition to displaying generator output conditions, control and alarm relays are programmed to activate alarms for measured output values, i.e. high or low current and voltage conditions. 12.1.4 Fire and Gas Monitoring The fire and gas detection system is comprised of plug-in modules that link to flame, temperature, and gas detection sensors inside the turbine enclosure. The fire and gas detection system interfaces with the turbine control system to provide the necessary engine shutdown, ventilation fan on/off signals, and other operator messages. 12.1.5 Generator Controls The GE AVR, EX2100 Brushless Regulator System is designed to control the excitation of a brushless generator.

15. Maintenance, Special Tools and Spare Parts
15.1 LM6000 Maintenance Advantages Down time is costly and in addition to labor and material for repairs, the owner loses profits while the turbine is down for maintenance. In most instances, the lost profit during down time exceeds the cost of repairs.
The LM6000’s simplified design helps reduce these field costs. The entire LM6000 package is designed for easy maintenance. Enclosures are large and provide ample working space. Components are accessible and easily adjusted or repaired, and an internal bridge-crane speeds engine removal for major repairs.
The result is more “up-time” and less “down-time.” The LM6000 fleet of generator sets operated by GE Energy has an average reliability of 99.5%, exceeding the industry average by almost a full percentage point. The LM6000’s simple package design and easy replacement of turbine modules contributes to this fine result.
15.2 LM6000 Repairs
To speed repairs, members of GE’s engine lease pool can have stock replacement engines dispatched to the job site for either planned repairs or an unscheduled overhaul.
The owner of an LM6000 package can easily remove the entire turbine engine in the event of serious failure. A replacement engine can be installed and on-line within 48 hours, and the customer's operations can return to normal while the engine is being repaired off-site.
15.3 Engine Compartment Design
The GE Energy engine compartment includes a shock isolation mounting system that permits the LM6000 turbine to ship in the package. This eliminates field reassembly. The turbine arrives tested, wired and fully piped.
The engine compartment includes built-in lighting, walkways and comfortable working space. The overhead bridge crane can easily lift and turn the engine for removal through the side doors.
15.4 “On Condition” Maintenance Maintenance on many gas turbines is scheduled on a “clock-hour” basis. Parts are replaced after a set number of operating hours. This can lead to unnecessary costs and maintenance.
LM6000 - 60 Hz Classic 6/2008 Page 106 of 156
The LM6000 is designed for “On-Condition” maintenance. Every six months the engine is given a thorough borescope inspection. Twenty-one borescope ports permit close inspection of all major internal parts.
15.5 Preventative Maintenance Inspection
This inspection reveals wear and mechanical problems. Maintenance is scheduled only when inspection shows a specific need, rather than replacing parts on an arbitrary schedule.
GE Energy literature and training stress preventative maintenance and operator awareness. We teach the customer's operators to perform preventative measures, including:
• Condition monitoring of critical parameters
• Trend analysis of performance
• Visual inspection of auxiliary systems and external wiring
• Borescope inspection
• Water wash
• Filter changes and inspections
• Lube oil sampling In addition, GE Energy teaches operators to perform routine " condition monitoring, " including:
• Gas generator speed
• Power turbine speed
• Gas generator exhaust gas temperature
• Gas generator discharge pressure
• Vibration
• Oil pressure
• Oil temperature Condition monitoring, in conjunction with borescope inspections, can provide an essential history of engine condition-versus-operating time. This allows maintenance to be predicted and scheduled for an appropriate time. 15.6 Maintenance Levels
Downtime for maintenance is reduced by the LM6000's modular design. Routine maintenance tasks are done on-site, while major engine repairs are performed at specialized off-site
LM6000 - 60 Hz Classic 6/2008 Page 107 of 156
facilities, saving the customer the expense of tooling and equipment. On-site and off-site maintenance tasks are divided into categories, or “levels,” described below. 15.7 On-Site Maintenance
15.7.1 Level 1 On-site external maintenance and module replacement includes protective and corrective tasks such as:
• Adjusting or replacing externally accessible components
• Engine replacement 15.7.2 Level 2 On-site internal maintenance requiring partial disassembly of the engine and replacement of components includes:
• Compressor blade/vane replacement
• Hot section component replacement
• HPT blade replacement
• Gearbox replacement
15.8 Off-Site Maintenance
15.8.1 Level 3 Off-site internal maintenance. Includes all Level 2 capabilities, plus complete teardown and rebuilding of engine. Includes replacement of major subassemblies with spare subassemblies. 15.8.2 Level 4 Off-site overhaul. Includes Level 3 capabilities plus complete disassembly of the major subassemblies of the gas turbine and rebuilding subassemblies with replacement parts. A permanent shop and a test cell are required for a Level 4 overhaul facility. GE Energy has full Level 4 maintenance capabilities for customer’s needs. We feature full-load testing of the repaired engine to ensure maximum field performance.
15.9 Owner’s Maintenance
LM6000 - 60 Hz Classic 6/2008 Page 108 of 156
In most cases, the Owner prefers to have his operators trained to perform Level 1 maintenance to the gas turbine, and Levels 2-4 maintenance tasks handled by outside contract. However, GE Energy can train operators for Level 2 maintenance tasks, if desired.
15.10 Special Tools Special tools are required to perform Level 1 and Level 2 maintenance activities. These tools are listed on the following pages and are priced separately for customers intending to perform maintenance themselves.
GE Energy includes a lift fixture for the LM6000 turbine engine in the basic scope of supply. This fixture and the built-in crane are used during engine removal and replacement.

17. Extended Scope Equipment and Services
Overview
GE Energy has the capability to provide everything from individual pieces of balance of plant equipment to the complete power plant supplied on a “turn-Key” basis. GE Energy has a dedicated team of engineers who specialize in the design, procurement and construction of power plants and has successfully demonstrated the ability to do so for the following types of facilities: • Simple Cycle Power Generation • Cogeneration Power Plants • Combined-Cycle Power Plants • Turbine-Compressor Plants • Compression Modules GE Energy designs power plants with a focus on reliability and availability. Turn-Key Services
Engineering GE Energy can provide complete power plant design services, including civil, mechanical and electrical design. The plants we design are reliable and intended to maximize the owner’s profitability and minimize the total installation and construction duration. In order to achieve this, we utilize pre-engineered designs for plant applications wherever possible. These designs are proven and are ready for use today, saving engineering costs and project time, allowing for the lowest installed cost basis. To meet unique project requirements, we work with the Owner to adapt GE Energy’s standard plant designs to accommodate their particular needs. Most of our designs are for shop built modules or systems, reducing the complexities of field installation. This process saves weeks of time and hundreds of engineering man-hours.
Most of our simple-cycle engineering is done “in-house” to provide tight coordination for our customers. On large projects we call in experienced third-party engineering companies to
Our field experience simplifies the job by bringing the knowledge and engineering skill gained from previous power plant projects to each new project.
LM6000 - 60 Hz Classic 6/2008 Page 130 of 156
work under our supervision. This approach helps us put units “on-the-line” quickly to meet owner’s deadlines.
Procurement The GE Energy Extended Scope engineering team can provide procurement services for the entire power plant. We use the experience of the GE Energy organization to help us find the best balance of plant equipment vendors in the business. We utilize GE components to the extent possible to minimize cost, ensure highest quality, and maximize standardization between balance of plant components and the turbine package. We demand quality, dependability, and experience from each of our vendors while keeping an eye on minimizing installed costs. Most pieces of major equipment are purchased from vendors who have served us for years, with hundreds of successful applications.
Construction Services and Start-Up Services The GE Energy project execution team can provide full construction and start-up services for the power plant. We place an experienced Construction Manager on each site. The Construction Manager and specialists from our Houston office select from a group of pre-qualified construction sub-contractors to provide skilled craftsmen for the job. The Construction Manager schedules and coordinates the work of the subcontractors. This individual verifies the quality and completeness of each element of the job, and ensures that the work progresses properly, with order and safety. A team of start-up specialists from GE Energy and from major equipment vendors arrives at the job when construction is nearing completion. These technicians check each plant system carefully. Then, in parallel with the combustion turbine Technical Advisory team and plant operations team, they commission the plant. After thorough operating checks, these specialists prepare the plant for performance testing and eventual turnover to plant operators. Extended Scope Services

19.10 Lease Pool Programs 19.10.1 Overview The GE Lease Program is designed to help customers minimize or reduce their overall life cycle costs and offers a low cost way for customers to maintain availability of their gas turbines. Customers can maximize site availability by leasing equipment from GE when their own equipment is at a Service Center for repair or when it cannot be repaired on site within a reasonable amount of time. Lease customers can continue operations to serve their customers and meet their business objectives. Lease assets are provided under either of two lease agreement concepts: Member or Non-member. GE has made the capital investment in these gas turbines and incurs costs for every operating and non-operating hour. Member and non-member rates and options are structured to reflect this. 19.10.2 Lease Engine Membership A member agreement is a contract of six-year duration. It provides a guarantee of availability if the customer should need a lease gas turbine. The customer pays an annual membership fee and a weekly usage fee whenever a lease asset is installed at the customer site. Weekly fees are subject to Special Applications adjustments for liquid fuel operation, STIG, and SPRINT™ water injection applications. 19.10.3 Lease Engine Usage by Non-Members A customer who has not opted for the six-year membership agreement may use a GE lease asset on a single event basis under the terms of a Non-member agreement. No guarantee of availability exists for non-member usage. An installation fee and a higher weekly charge apply to non-members. Non-member lease rates are calculated from the rates in the member tables. The weekly non-member rate is 3.5 times the weekly member rate, after any Special Applications adjustments. An installation charge applies to each usage plus actual transportation costs each way. Note: New customers who request a lease gas turbine within 45 days of executing a member lease agreement will be charged at non-member rates for that lease usage event. 19.11 Field Services 19.11.1 Overview GE Energy Field Service is a world-class service and support network designed to anticipate and respond to our customers needs throughout the product life of GE LM6000 gas turbine and packages.
