The MiCOM Interconnection Protection Relays

offer the protection requirements necessary for

operating machines in parallel with the main

power supply network. They provide flexible and

reliable integration of protection, control,

monitoring and measurements. Extensive

functionality is available to satisfy complete

protection and control for a wide range of system

applications, including protection for both

connection and generator in simple applications

or the more sophisticated interconnection

protection necessary for larger units or those

connected at higher voltages.

The variable number of opto inputs and output

contacts available allow complex protection

schemes to be created using the relay's powerful

but easy to use logic.

A customer choice of industry standard protocols

are available on the relay, facilitating an easier

integration into both new and existing network

control systems.

APPLICATION

With embedded generators running in parallel with the

normal public supply there is a risk that, due to fault

clearances on the external system, the embedded

generator may become disconnected from the main

supply network. The machine may continue to supply

external load and there is a significant risk of

unsynchronised reconnection due to auto-reclosure of

the remote circuit breaker. A range of protection

functions are provided to detect this condition.

Loss of mains techniques are provided as well as the

more traditional functions encompassing voltage,

frequency and power elements.

The P341 provides overcurrent and ground fault, under

and overvoltage, under and overfrequency, thermal

overload, negative phase sequence overcurrent and

overvoltage and power protection for the generator.

In addition, rate of change of frequency and voltage

vector shift protections are provided for loss of mains.

The P922G provides , under and overvoltage, residual

voltage and under and overfrequency protection.The P922G meets the specifications of EDF GTE 2666

and is only available in the French language with

MODBUS communications.

GLOBAL FUNCTIONS

The following global functions are generally available in

both devices :

> Under/over voltage protection

> Under/overfrequency protection

> Residual overvoltage protection

> Metering

> Event recording

> Disturbance recording

> Fault recording

> Breaker condition monitoring

MAIN PROTECTION FUNCTIONS

The main protection functions are autonomous and can

be individually enabled or disabled to suit a particular

application. Each protection function is available in 4

separate setting groups (P341) and 2 (P922G) which

can be individually enabled or disabled.

Three phase tripping with faulted phase indication is

provided for all protection functions.

The IDMT stages have a programmable reset timer for

grading with electromechanical relays, to reduce

autoreclose dead times and to reduce clearance times

where intermittent faults occur.

The phase fault directional elements are internally

polarised by quadrature phase-phase voltages, and

will make a correct directional decision down to 0.5V

(Vn = 110/120V) or 2.0V (Vn = 380/440V). A

synchronous polarising signal is maintained for 3.2s

after voltage collapse to ensure that the instantaneous

and time delayed overcurrent elements operate

correctly for close-up three phase faults.

> Standard ground fault (P341)

The standard ground fault element operates from a

residual current that is derived internally from the

summation of the three phase currents.

The directionality of the ground fault elements is

provided by either residual voltage or negative

sequence voltage.Voltage transformer supervision

(VTS) can be used to block the directional element or

to revert it to non-directional.

> Sensitive ground fault (P341)

A core balance CT should be used to drive the

sensitive ground fault function. The directionality of the

sensitive ground fault elements is provided by the

residual voltage.

> Wattmetric (P341)

The sensitive ground fault protection is also suitable for

Petersen Coil grounded systems by enabling a

wattmetric element.This form of protection uses the

sensitive ground fault protection directional

characteristic, but with a directional residual power

threshold providing an additional constraint on

operation.

> Restricted ground fault (P341)

The sensitive ground fault element may be configured

as a high impedance differential restricted ground fault

element. When high impedance resticted ground fault

protection is used an additional stabilising resistance

and a metrosil will be required.

> Loss of mains (P341)

In order to protect against unsynchronised

reconnection due to autoreclosure of a remote circuit

breaker onto a system which has become

disconnected from the mains, specific protection is

required. Loss of the grid connection can be protected

against using voltage, frequency and power protection,

but, when the machine rating closely matches the

connected load this condition may be difficult to detect.Two methods of detection are therefore offered, rate of

change of frequency and voltage vector shift.

> Rate of change of frequency (P341)

This element detects the fluctuation in frequency that

will occur as the machine adjusts to the new load

conditions following loss of the grid. It is inherently

damped allowing sensitive settings to be used.

To improve stability for external system events an

adjustable definite time delay can be used.

> Voltage vector shift (P341)

This protection measures the instantaneous change in

the three phase voltage angle that occurs when the

connection to the main supply network is lost. To

provide stability this element must be less sensitive

than the rate of change of frequency element.

However, it operates without any intentional time delay,

providing fast tripping.

> Phase overcurrent (P341)

Four independent stages are available for each phase

overcurrent, ground fault and sensitive ground fault

element.Each stage may be selected as non-directional or

directional (forward/reverse). All stages have definite

time (DT) delayed characteristics, two of the stages

may also be independently set to one of nine inverse

definite minimum time (IDMT) curves (IEC and IEEE).

> Blocked overcurrent logic (P341)

Each stage of overcurrent, ground fault and sensitive

ground fault protection can be blocked by an optically

isolated input. This enables the overcurrent and ground

fault protection to be integrated into a blocked

overcurrent busbar protection scheme.

> Neutral displacement/residual overvoltage

(P341/P22G)

Three stages of residual overvoltage (or neutral voltage

displacement) protection are provided within the P922G

and two stages in the P341. Depending on the VT

configuration set on the relay, the protection will

operate from either an internally calculated value from

the 3 phase to neutral voltage measurements or a

directly measured value of residual voltage from a

broken delata VT or from the secondary winding of a

distribution transformer ground at the generator neutral.

The fist stage can be configured for either inverse time

or definite time operation, with all subsequent stages

definite time only.

This function provides protection against ground faults

irrespective of the system grounding connection used.

> Under/overvoltage (P341/P22G)

Under/overvoltage protection may be configured to

operate from either phase-phase or phase-neutral

voltage elements and from Any Phase variation

(OR mode) or Three Phase variation (AND mode).

Two independent stages with definite time elements are

available for under and overvoltage protection.

The first stage can also be configured to an inverse

characteristic.

> Under/overfrequency (P341/P922G)

The P341 provides two independent stages of

overfrequency and four of under frequency. The P922G

provides 6 stages of frequency protection, each stage

can be set for under or over frequency operation.

Each stage functions as a definite time element.

> Power protection (P341)

The selectable power element can be used to provide

loss of mains protection whether the normal power flow

is into or out of the utility system, tripping when import

power reverses, or export power exceeds normal limits.

In addition to the standard 3 phase power protection

(minimum setting 2% Pn) a sensitive single phase

power protection element can be used (minimum

setting 0.5% Pn) which uses the sensitive ground fault

current input.

> Thermal overload (P341)

To monitor the thermal state of a generator or a feeder,

a thermal replica protection is provided. The thermal

element has a trip and an alarm stage. Positive and

negative sequence currents are taken into account so

that any unbalance condition can be detected and any

abnormal heating of the rotor can be avoided. There

are separate time constants for heating and cooling

and in the event of loss of auxiliary supply the thermal

state is stored in non volatile memory.

> Negative phase sequence overcurrent (P341)

Four definite time negative phase sequence overcurrent

stages are available within the P341.

Each stage may be selected as non-directional or

directional (forward/reverse) and can operate for

remote phase-phase and phase-ground faults even with

delta-star transformers present.

> Negative phase sequence overvoltage (P341)

One definite time stage of negative phase sequence

overvoltage protection is provided within the P341.

Negative phase sequence overvoltage protection can

be used for the detection of voltage unbalance which

will quickly lead to overheating and damage of

generators.

> Analog (Current Loop) Inputs and Outputs

(CLIO) (P341)

Four analog (or current loop) inputs are provided for

transducers with ranges of 0-1mA, 0-10mA, 0-20mA or

4-20mA. The analog inputs can be used for various

transducers such as vibration monitors, tachometers

and pressure transducers. Associated with each input

there are two time delayed protection stages, one for

alarm and one for trip. Each stage can be set for 'Over'or 'Under' operation.

Four analog (or current loop) outputs are provided with

ranges of 0-1mA, 0-10mA, 0-20mA or 4-20mA which

can alleviate the need for separate transducers.These

may be used to feed standard moving coil ammeters

for analog indication of certain measured quantities or

into a SCADA using an existing analog RTU.

SUPERVISORY FUNCTIONS

> Circuit breaker failure protection (P341)

Two stage circuit breaker failure protection may be

used for tripping upstream circuit breakers and/or the

local secondary trip coil.The circuit breaker failure

logic may also be initiated externally from other

protection devices if required.

> Voltage transformer supervision (P341)

Voltage transformer supervision (VTS) is provided to

detect loss of one, two or three VT signals, providing

indication and inhibition of voltage dependent

protection elements. An optically isolated input may

also be configured to initiate the voltage transformer

supervision alarm and blocking when used with

miniature circuit breakers (MCBs) or other external

forms of voltage transformer supervision.

> Current transformer supervision (P341)

Current transformer supervision (CTS) is provided todetect loss of phase CT signals and inhibit the

operation of current dependent protection elements.

PLANT SUPERVISION

> Trip circuit monitoring (P341)

Monitoring of the trip circuit in both breaker open and

closed states can be realised using the programmable

scheme logic.

> Circuit breaker state monitoring

In the P341 an alarm will be generated if there is a

discrepancy between the open and closed contacts of

the circuit breaker.

> Circuit breaker condition monitoring

The circuit breaker condition monitoring features

include:

monitoring the number of breaker trip operations

recording the sum of the broken current quantity

Ix, 1.0 x 2.0 (P341 only)

monitoring the breaker operating time

monitoring the fault frequency counter

(P341 only)

CONTROL

> Circuit breaker control (P341)

Circuit breaker control is available from the front panel

user interface, optically isolated inputs and remotely via

the substation communications.

> Programmable scheme logic

The P922G uses simple logic to program the digital

inputs, output contacts and LED's.

Programmable scheme logic in the P341 allows the

user to customise the protection and control functions.

It is also used to programme the functionality of the

digital inputs, output contacts and LED indications. The

programmable scheme logic comprises gate logic and

general purpose timers.The gate logic includes OR,

AND and majority gate functions, with the ability to

invert the inputs and outputs, and provide feedback.

The system is optimised to evaluate changes to the

scheme logic signals and thus minimise any delays in

logic execution. The programmable scheme logic may

be configured using the graphical MiCOM S1 PC basedsupport software, as illustrated in Figure 2.

The required logic is drawn as shown and is then

downloaded directly into the relay. The logic may also

be uploaded from the relay and then modified using

MiCOM S1 support software.

> Control inputs (P341)

The ON/OFF status of 32 control inputs can be

changed manually or remotely via the communications

to provide user defined control functions within the

P341 PSL.

> Latched output contacts

Each P922G and P341 relay output contact can be

individually programmed to be latched. Once in the

latched state, the contact can be reset either locally or

remotely (P341/P922G), or via the PSL in the P341

relays.

In addition to the ability to latch output contacts, on the

P341 relays, each of the contacts can be individually

conditioned by a timer to give pulse, dwell, delay on

pick-up or delay on drop-off operation.

MEASUREMENTS &POST FAULT ANALYSIS

The P341 and P922G are capable of measuring andstoring a number of quantities. All events, faults and

disturbance records are time tagged to a resolution of

1ms using an internal real time clock. On the P341

relays a pulsed opto input or an optional IRIG-B port is

also available to maintain the accuracy of the real time

clock. A supervised and easily accessed lithium

battery ensures that the real time clock and records

are maintained during auxiliary supply interruptions.

> Power System Measurements

The measurements provided will depend upon the

application and model of the relay. Where appropriate

the measurements may be viewed in primary or

secondary terms and can be viewed locally or

remotely.

Measurements include:

Phase / line voltages

Sequence voltages

Phase angles

System frequency

Phase / line currents (P341)

Sequence currents (P341)

W/Var/VA (P341)

> Event Recording

The P922G can store up to 75 event records for

viewing via the local and remote communication

ports using MiCOM S1. The P341 relay can store up to

512 event records for viewing locally on the LCD, or

extraction via the communication ports.

> Fault Recording

The relays store the last 5 faults records, typically

containing:

Date and time

Protection operation

Active setting group

Fault voltages, frequency, etc..

> Disturbance Recording

The relays have an internal waveform capture facility

with a user programmable trigger point. The P922G

can record five disturbances, each with a duration of

2.5 seconds at a sampling rate of 32 samples per

cycle.The P341 can record 10 disturbances, each witha duration of 7.5 seconds (75s maximum) at a

sampling rate of 24 samples per cycle. All disturbance

records capture both analog and digital information

and when extracted via the communication ports, are

stored in Comtrade format.

These records can be examined using MiCOM S1 or

any other suitable software programme.
