Page 25 6F2S1914 (0.49) GRL200 line differential protection has been designed to provide phase-segregated current differential protection with digital telecommunications, together with control applications. The GRL200—intelligent electronic device (IED)—provides the user with the flexibility to meet their application and engineering requirements in addition to offering excellent performance, the high quality and reliability.
Page 26 6F2S1914 (0.49) Figure 1.1-2(b) exemplifies that both the forward line and the busbar are protected using a CT. Once a fault occurs between the CT and the CB , the relay Ry for the forward line can operate, but the relay Ry for the busbar may fail to operate to clear the fault.
Page 27 6F2S1914 (0.49) Reliability (iii) The relay is in a quiescent state normally, but the relay shall respond to a fault instantly once it occurs on the power system. Hence, the operation availability shall be checked whenever the line is energized in unfaulted state. Additionally, to improve the operation reliability, the protection scheme is checked externally by fail-safe function (FS).

Page 31 GR200 series relay provides the block function for power swing (PSB) so that preventing unwanted tripping is possible during the power swing. Figure 1.1-5 illustrates the typical impedance locus as seen by the distance relay during the transient power swing.
Page 32 6F2S1914 (0.49) Distance protection characteristic (Mho) Impedance locus during transient power swing Load Area Figure 1.1-5 Impedance locus during transient power swing A special case of the power swing condition occurs when the power system disturbance is so severe that generators lose synchronism with each other and are said to be out-of-step. During an out-of-step condition the phase angle between generators continues to increase and pass through 180°, at which point a distance relay measures an impedance equal to that for a three phase fault at the center of the power system.
Page 33 Consequently, at each ends, the trip command can be issued faster. The GR200 series can provide the following carrier command schemes using the elements of the ZS/ZG function.

Page 47 6F2S1914 (0.49) Current differential protection for the line Current differential protection function (DIF) at local-terminal and remote-terminal can operate by comparing the currents flow in and out in the line. The value of the current- difference is close to zero when a fault does not occur (i.e., No fault). The DIF function consists of a current segregated current differential protection (DIFL) and a zero-sequence current differential protection (DIFG);...
Page 48 6F2S1914 (0.49) Segregated-phase current differential protection function (DIFL) The principle of current differential protection (DIFL) function is to compare the currents flowing into and out of the transmission line; the differential current is obtained by the comparison between two currents in the DIFL function. In the DIFL function the value of the differential current is almost zero when a fault occurs out of the protection zone (i.e., external fault).

Page 140 6F2S1914 (0.49) Common application for ZS and ZG 2.10.4 Applications in ZS and ZG are divided into common features and special features. Each feature secures this distance protection function. Power swing block Operation of power swing block (PSB) Power swings occur when the output voltages of generators located at different points in the power system slip relative to one another because of system instabilities.

Page 314 6F2S1914 (0.49) Circuit breaker fail protection (CBF) When a circuit breaker (CB) fails to remove a fault as a consequence of the CB failing to open, the function of circuit breaker fail protection (CBF) is to remove the fault by the back-tripping of other CBs.
Page 315 6F2S1914 (0.49) CBF operation and its elements 2.20.1 The operation of CBF is initiated by the operation of OCCBF and EFCBF, which monitors fault current after the issuance of a trip signal by other protection functions. OCCBF or EFCBF monitor the fault current so that the CBF feature can determine the failure of the CB to operate. For CBF, the respective phase currents in three-phase system are monitored by the OCCBF- A, OCCBF-B and OCCBF-C elements, while the zero-sequence current is monitored by the EFCBF element.
Page 316 6F2S1914 (0.49) One of the benefits of the “re-trip” function is that it can used to avoid accidental tripping of an adjacent CB or an upstream CB. This is particularly requisite during maintenance and testing of the system. Retrip Backup feature 2.20.3 Normal trip As cited above, “re-trip”...

If the target CB were to fail to remove the fault with the “re-trip” command, and if OCCBF or EFCBF continued to operate and if the timer #2 were to time out in accordance with the setting time applied [TCBF1-TP], CBF will issue a trip signal to the adjacent CB(s) to clear the fault, as a last resort.

Page 517 6F2S1914 (0.49) Transmission control function (DIF_COMM) In order that several protection functions can handle their computation diversely, the transmission control (DIF_COMM) function is provided along with protection signalling modules†. The DIF_COMM function operates with the telecommunication system; the telecommunication medium is provided such as dark fiber (dedicated fiber-optic cable), multiplexed fiber-optics, digital microwave, and others.
Page 518 6F2S1914 (0.49) Data communication interface 2.36.1 Communication interface is relevant to the property and capacity of channels; hence, IEEE C37.94 (either N=1 or N=3) is provided in the DIF_COMM function. Securing clock recovery, jitter tolerance, physical connection, and spuriousness are specified by the international standard.
Page 519 6F2S1914 (0.49) example. IEEE C37.94 (N=3) (ii) The IEEE C37.94 (N=3) is provided when the transmission capacity is wider† than the IEEE (N=1); the DIF_COMM function can also transmit current data at pre-sampling time; consequently the computation range is extended dynamically. Thus, the computation performance and accuracy are improved in the differential and other protection functions.
Page 520 6F2S1914 (0.49) Figure 2.36-1 shows two IEDs arrangement when two IEDs connect with a channel. In the arrangement, the user can select IED_G as the master and should set 1 for the scheme switch [TERM_ID], whereas the user should select another IED_H as the slave and set 2 for the scheme switch [TERM_ID].

( �� ) + ( �� − �� − �� 1 ��2 (2.36-2) ∆T = (2.36-3) − T The delay difference (T dd ) between sending and receiving is determined with Equation (2.36-2); you should set the difference (T dd ) as zero in all the IEDs when the upstream and the downstream are carried out with the same route.
Page 524 6F2S1914 (0.49) In Figure 2.36-7, the slave IED_H sends a timing reference signal at point (1). The master IED_G receives this signal at point (2). You can find that the master IED_G replies this signal at point (3). Finally, at point (4), this signal reverts to the slave IED_H again. When the δ is placed in Figure 2.36-7, the following equation is obtained with the T d1 , the T d2 , and the T M : (2.36-4) −...

As for the operation of two IEDs on a line, suppose an IED is taken out-of-service, another IED can continue to operate the differential protection function with the local current data.
Page 527 6F2S1914 (0.49) Star mode (ii) When a three-terminal line application is applied, the star mode is selected. As seen from Figure 2.36-10, the IED is connected with the others with a bidirectional channel, provided two or more IEDs exist. When switching of channel route is occurred, and the fluctuation of channel delay is appeared, the IED corrects the channel delay automatically.

Page 584 6F2S1914 (0.49) Common controls (CMNCTRL) The CMNCTRL function consists of two parts. The former part (CMNCTRL1) is used to prevent double-commands, which are forbidden, by the use of select-states for the respective control functions. The latter part (CMNCTRL2) is served as a mediator to provide a bridge between functions.
Page 585 6F2S1914 (0.49) Double command blocking (DCB) 3.4.1 For control functions, the operating principle is that priority is given to the first command received and shall be executed first. In other words, successive commands received do not have the right to run until the first command received has failed to complete its operation (that is, the principle of double command blocking (DCB) is established).
Page 586 6F2S1914 (0.49) Automatic sequence controlling function In Figure 3.4-1, the CMNCTRL1 function generates a message denoted with the number 1; Figure 3.4-2 exemplifies that the IED-1 generates the “stVal” message 1.

Page 693 6F2S1914 (0.49) Double position controller with synchronizing-checking (DPSY) The double position controller with synchronizing-check (DPSY†) function is used when the user wishes to control a device from the “Closed” or “Open” condition. Generally, the device controlled by the DPSY function is either a 43-switch or a CB. The DPSY function has two measurements: an operation counter and an operation timer.
Page 694 6F2S1914 (0.49) Two devices can be controlled separately; i.e., the DPSY function has two separate sets of logic for control (i.e., DPSY01 and DPSY02 functions). For simplicity, only the DPSY01 function is discussed here; the features in the DPSY02 function are identical to the DPSY01 function. Select logic for SBO/DIR modes 4.2.1 The user should set scheme switch [DPSY01-CTREN] On prior to DPSY01 operation.

Page 806 6F2S1914 (0.49) Total time measurement function (TOTALTIM) The total time measurement function (TOTALTIM) measures the time of the On state using a signal which is selected with the logic programmed by the PLC function. The TOTALTIM function increments the time for which the signal is in the “ON” state and stores it as a cumulative time.
Page 807 6F2S1914 (0.49) Operation feature 4.5.1 Time accumulation process Figure 4.5-1 outlines the time accumulation process within the TOTALTIM function. The TOTALTIM function accumulates the time for which the state of the operating signal is in the “ON” status every second. The accumulation process continues until the maximum accumulated time reaches 10,000 days (almost 27 years).

Unsuccessful synchronization check If the injected signal “DPSY01_OEC_RCV” persists for longer than a pre-determined time, the check logic determines that synchronization has not occurred; hence, the check logic can issue a failure signal for the DPSY01 function. Consequently, the DPSY01 function abandons the attempt to close the CB due to the failure in the synchronization process.

The latter is used for an event suppression detector. Decision by input signals The logic in Figure 4.9-55 can give a decision in response to the reception of the signals; the decision is of either “P1”, “P2”, “P3”, “Faulty”, and “Intermediate”.
Page 990 6F2S1914 (0.49) Event suppression detector If the status of a device “chatters” for a short time, the TPOS function will receive iterative signals from the device. Such iterative signals can cause extra burden for the TPOS function; hence, event suppression can be required to reduce the additional burden created. [TPOS-NELD] Signal from device...
