RESPONSIBILITIES AND AUTHORITIES

The main power plant is operated round the clock, throughout the year. To ensure uninterrupted operation, the operation staff is divided in to four groups. Each day is divided in to three shifts viz. Morning shift, Evening shift & Night shift.

Shift Charge Engineer (SCE):In each shift main plant operation is headed by SCE, who is responsible for all activities of process control system during his shift. SCE takes instructions from HOD(Opn) and takes decision to meet the requirements of process control system. He is given generation schedule from NRLDC / NCRHQ through switchyard or directly to the SCE and instructs all the MODULE ENGINEERS about the schedule and Unit load to be maintained, depending upon the Unit constraints and grid requirements. In the morning shift SCE reports all the major problems and pending problems in the Daily planning meeting. SCE acts as a nodal point in case of any emergency. SCE is assisted by MODULE Engineers who co-ordinates the operational activities of the whole plant with special attention to Common utilities like Switch Yard , Fuel Oil Pump House , Compressor House, CW Pump house & Raw Water Pump House. SCE maintains a record of activities during the shift & availability of equipment and their defects. MODULE Engineer : The MODULE ENGINEER is the in-charge of the concerned unit and is responsible for all the processes & activities of that Unit. MODULE ENGINEER takes Instruction from the SCE about unit load, startups & shutdown of the unit. MODULE ENGINEER monitors health of all equipment and plants and raises equipment defects, issues PTW, cancels PTW and checks the availability of stand by equipment. To assist the Unit operation, supervisors & local operators are posted in each unit and they work according to the instructions given by the control engineer.

OFFSITE Engineer : OFFSITE ENGINEER is responsible for carrying out safe & efficient operation of switchyard AND OTHER OFF SITE AREAS.

Sl.No. Activity Responsibility Ref. Doc. The abnormal variation of any of the above storage vessel level will lead to the failure of the pump, which is taking suction from it. This calls for maintaining correct level in these vessels to prevent the failures. The Boiler drum level control is of utmost importance as low drum level may cause the starvation of boiler tube and its failure & high drum level may cause priming and water carry over to the turbine. To prevent this the Boiler drum level is maintained with in limits by FRS control valves. DP is maintained across the FRS control valve to ensure required feed water flow to Boiler drum by varying BFP speed with the scoop control mechanism. The Boiler feed pump draws water from the Deaerator, whose pressure is maintained by supplying steam to it, in order to provide positive NPSH to BFP. Deaerator level is maintained by supplying condensate water through CEP, which draws water from Hotwell. The Hotwell receives the condensate from the condensation of steam in condenser. The Hotwell level is controlled by adjusting the condensate flow to Deaerator through a control valve. Low Deaerator level is corrected by supplying cycle make up water to the Hotwell and high Deaerator level is corrected through an overflow valve.

Sl.No. Activity Responsibility Ref. Doc. Condenser back pressure is maintained by creating vacuum in condenser by drawing out the non condensable gases as well as by condensing the LPT exhaust steam with the proper cooling water flow. Deviations in the condenser back pressure are corrected by giving proper CW flow in condenser to effectively condense the LPT exhaust steam & preventing air ingress to the condenser.Deviation in condenser back pressure from its design value causes cycle inefficiency and large deviations in it may lead to LP blade overheating & its failure. To prevent this the condenser back pressure is maintained with in limitsTG lube oil & Governing System The TG lube oil system lubricates the bearings of the Main TG & also carries away the heat produced in the TG bearings. The lube oil systems basically consist of Main oil tank which stores the governing/lube oil. It consists MOP (mounted on Main TG shaft), AC LOP, DC LOP & lube oil coolers. The Governing system controls the output & speed of the Turbo Generator (TG) through stop valves and control valves at the steam entrance of HP & LP Turbine.

Monitoring of TG lube oil & Governing System Under this system, following inspection & testing are conducted by the MODULE ENGR. on regular basis for smooth running of the unit . a. MOT level b. TG lube oil temperature.

c. TG bearing temperature/vibration. d. Availability of AC LOP, DC LOP Main oil tank is reservoir of lubrication oil for TG bearing and Seal oil system of generator. Lube oil is provided by the shaft mounted MOP which is in running along with main turbine, however, if the lube oil pressure falls due to any reason, Standby lube oil pumps are taken in service to prevent the TG bearing from failure. These standby lube oil pumps (AC LOP and DC LOP) are checked regularly, to ensure their availability. Most of these parameters are available on DAS system for regular monitoring.







Generator System: The mechanical energy is converted to the electrical energy ( Product ) in the generator and is supplied to the switchyard via GT at 400 KV.. Rotor and other elements of the generator are cooled by the hydrogen gas, which circulates in the generator by the shaft-mounted fans and is in turn cooled by the cooling water in the gas coolers. To have effective cooling, hydrogen gas is filled at high pressure. This hydrogen gas is sealed by generator seal oil system at both the ends. Sealing at both ends of generator is done by providing the seal oil at higher pressure than generator hydrogen pressure. In order to prevent escapement of hydrogen as well as the formation of explosive mixture of hydrogen & air, Seal oil to hydrogen differential pressure is maintained with the available control system. The availability of DC SOP are checked regularly. The deviation in seal oil temp is corrected byregulating cooling water flow to seal oil coolers. The generator voltage is maintained by AVR, it is kept under constant watch & corrective actions are initiated in case of its deviation or generator instability by changing excitation. Stand by exciter is readily available to meet the main exciter problem of any unit.

Doc. Corrective and preventive Actions for Switchyard Engineer Electric power generation in all units is maintained by SCE/ MODULE ENGINEER as per generation schedule, this as the final output flows to the 400 kV Switchyard. From switchyard this power instantaneously goes to the grid through 400 KV and 220 KV lines. The switch yard Incharge keeps a close watch on the out put of all units & the line loading of all the 400 KV and 220 KV lines. He also remains in touch with grid controllers about the availability & loading of other important transmission lines. In case of significant deviations in unit / line loading or any trip out in DGPS switch yard or other important generating station & transmission lines of Eastern grid, he takes corrective & preventive action by informing the SCE/MOD. ENGR. & coordinates with grid controller. The grid frequency and the bus voltage at DGPS end are also kept under close watch & in case of deviations in them, appropriate corrective actions are initiated by the switchyard Incharge by consulting SCE and grid

controlling authorities. All 400 KV & 220 KV equipments such as breakers, isolators, transformers, reactors, CTs & CVTs, are checked regularly for healthy functioning in order to prevent them from failure. SF6 pressure is watched and its deviations are corrected by getting defects attended by maintenance department in order to ensure healthiness of circuit breakers. For SF6

gas filled breakers, their gas pressure is watched & corrective actions are initiated in case of deviation (such as getting gas filled by maintenance department).
