  • Page 15: Current Differential Protection

    6 F 2 S 0 8 3 5 2.2 Current Differential Protection 2.2.1 Operation of Current Differential Protection Current differential protection compares the currents flowing into and out of the protected line. The difference of the currents, that is, the differential current, is almost zero when a fault is external or there is no fault, and is equal to the fault current when the fault is internal.
  • Page 16: Zero-Phase Current Differential Protection

    6 F 2 S 0 8 3 5 Tripping output signals can be blocked by the PLC command DIF_BLOCK and CRT_BLOCK. The output signals of DIF-A, DIF-B and DIF-C are also blocked when a communication circuit failure is detected by the data error check, sampling synchronism check or interruption of the receive signals.
  • Page 17: Fail-Safe Function

    6 F 2 S 0 8 3 5 The zero-phase current differential element has a percentage restraining characteristic with weak restraint. For details of the characteristic, see Section 2.11. The scheme logic is shown in Figure 2.2.3.1. The output signal of the differential element DIFG performs time-delayed three-phase tripping of the circuit breaker with the tripping output signal DIFG.FS_TRIP.

    6 F 2 S 0 8 3 5 2.2.6 Transmission Data The following data are transmitted to the remote terminal via the 64kb/s digital link. The data depends on the communication mode and whether a function is used or not. The details are shown in Appendix N.

The difference of the transmission delay time T dd (= T d1 − T d2 ) is set to zero when sending and receiving take the same route and exhibit equal delays. When the route is separate and the sending and receiving delays are different, T dd must be set at each terminal to be equal to the sending delay time minus the receiving delay time.
  • Page 23 6 F 2 S 0 8 3 5 T d = ({T o − (T − T M )}/2 + T dd )/2 The calculated transmission delay time T d1 is divided by the sampling interval T. The mantissa is truncated and the quotient is expressed as an integer. If the integer is set to P, the reception at the slave terminal of the signal sent from the master terminal occurs at P sampling intervals from the transmission.
  • Page 24 6 F 2 S 0 8 3 5 In the backup modes, the percentage restraint in the small current region can be increased from the normal 16.7% ((1/6)Ir in Figure 2.9.10.1) in accordance with the PDTD setting which is the probable transmission delay time difference between send and receive channels.

It is not employed in Mode 1 and 2B because the sampling address synchronization has already been established in the previous mode.

Scheme logic The scheme logic of the overcurrent backup protection is shown in Figure 2.3.1. The overcurrent protection issues single-phase tripping signals in the operation of OC and OCI, and issues a three-phase tripping signal BU-TRIP in the operation of EF or EFI element.
  • Page 43 6 F 2 S 0 8 3 5 2.3.1 Inverse Time Overcurrent Protection In a system in which the fault current is mostly determined by the fault location, without being greatly affected by changes in the power source impedance, it is advantageous to use the inverse definite minimum time (IDMT) overcurrent protection.
  • Page 44 6 F 2 S 0 8 3 5 The minimum setting is restricted so as not to operate on false zero-sequence currents caused by an unbalance in the load current, errors in the current transformer circuits or zero-sequence mutual coupling of parallel lines.

    6 F 2 S 0 8 3 5 2.5 Out-of-step Protection The GRL100 out-of-step protection (OST) operates only when the out-of-step loci cross the protected line and provides optimal power system separation in case of power system step out. The OST compares the phase of the local and remote positive sequence voltages and detects the out-of-step when the difference in the phase angle exceeds 180°.
  • Page 49 6 F 2 S 0 8 3 5 At terminal A, the terminal voltage V A is taken as a reference voltage. Then, the phase angle of the remote terminal voltage V B changes as shown in Figure 2.5.2. Out-of-step is detected when V B moves from the second quadrant to the third quadrant or vice versa.

  • Page 53: Breaker Failure Protection

    6 F 2 S 0 8 3 5 2.7 Breaker Failure Protection When a fault remains uncleared due to a breaker failure, the breaker failure protection (BFP) clears the fault by backtripping the adjacent breakers. If the current continues to flow following the output of a trip command, the BFP judges it as a breaker failure.
  • Page 54 6 F 2 S 0 8 3 5 The backtrip signal to the adjacent breakers CBF-TRIP is output if the overcurrent element OCBF operates continuously for the setting time of the delayed pick-up timer TBF2 after the start-up. Tripping of the adjacent breakers can be blocked with the scheme switch [BF2]. There are two kinds of mode of the retrip signal to the original breaker RETRIP: the mode in which RETRIP is controlled by the overcurrent element OCBF, and the direct trip mode in which RETRIP is not controlled.

If a transient fault occurs, the circuit breaker is tripped to isolate the fault, and then reclosed following a time delay to ensure that the hot gases caused by the fault arc have de-ionized.
