DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a reclosing device for a protective relay device, particularly a reclosing device for a protective relay device, which is divided into two series or duplexed by a first series device and a second series device, The present invention relates to a reclosing device for a protective relay device in which a first series of devices and a second series of devices share one set of reclosing devices and is equipped with an automatic inspection function. (The following is a blank space) [Technical Background of the Invention] In recent years, power systems have become increasingly high-voltage, and more reliable systems have been adopted for VC systems and protective relay devices, which are becoming increasingly important. As an example of this, many protective relay devices have been adopted that have two lines or duplexes from the system input to the circuit breaker disconnection coil.
It is well known that the reliability of the system's protection function can be improved by employing a multi-layered protective relay device.

In FIG. 1, the A series relay 8 and the B series relay 9 may each be the same protective relay device or different protective relay devices, but the purpose of the present invention is to combine them. Since this is not related to the method, the explanation will be omitted. If an accident occurs on the power transmission line 2 in Figure 1, the human line relays 8 and B
The series relay 9 includes a current transformer 3°, an instrument transformer 6, and a current transformer 4. Input amounts are individually introduced from the instrument transformer 7 to the protective relay, and internal and external faults are determined independently. In the case of an internal fault, the tripping coils 5 and 5B of the circuit breaker 5 are supplied with 8T and 9T, respectively. A tripping command is issued to the 4th gear. Furthermore, even if either one of the human series relay 8 and the B indicator 1 relay 9 becomes defective and no longer functions as a protective relay device, it can be tripped by the other protective relay device. By duplicating the protective relay device in this way, the reliability of the protective function is greatly improved.

On the other hand, automatic monitoring is generally employed to improve the reliability of the protective relay device itself. This automatic monitoring consists of two parts: constant monitoring and automatic inspection. Continuous monitoring is a method that determines an abnormality if an operation that would never occur under normal conditions continues for a certain period of time or longer, and mainly detects defects on the malfunction side. In addition, automatic inspection is a method of applying pre-scheduled input conditions to the input section of a protective relay and then checking whether an output that meets the input conditions can be obtained.It is mainly a method of detecting defects on the side that malfunctions. be.

In Fig. 2, the condition 11 selected for the use of the reclosing circuit
, the circuit breaker "close" condition 12, and the circuit breaker atmospheric pressure condition 13 are all satisfied by the AND circuit AND1, and the re-closing preparation is completed after the on-delay timer T1 for re-closing preparation has expired. If an accident occurs in the protected system in this state and trip signals 14A and 14B of the human series relay or B series relay occur, this is detected by the AND circuit AND2 and introduced into the input S of the holding circuit FFI. The holding circuit FFI holds it. The output Q signal is input to the off-delay timer T4 for measuring the re-closing no-voltage time, and after the on-delay timer T4 expires, if the re-closing closing condition 17 is satisfied (・), the closing command 18 is cut off from the AND circuit AND3. The circuit breaker closes. At the same time, the output of the AND circuit AND3 is output from the holding circuit FF1 after the input command confirmation on-delay timer T5 has expired.
The hold is reset and the reclose circuit is released. The time required to close the circuit is obtained by the on-delay timer T5. -If the accident in the power system is a permanent accident, the circuit breaker will be shut off again after it has been turned on, but we will explain how the final shutoff is detected by the re-shutdown.

This is the input of D4. One input of the AND circuit AND4 is a signal indicating that the circuit breaker is "open" Q after the occurrence of the accident and preparation for re-closing is not completed. The AND circuit AND5 detects that a re-shutoff is made with the A-series shut-off command 14A or the B-series shut-off command 14B in an incomplete state of preparation after re-turning on, and performs three-phase shutoff for final shutoff.

Next, A series cutoff command 14 people, or B series cutoff command 14B
The reason why the output time is extended by the off-delay timer T3 will be explained. During automatic inspection of the re-closing circuit, a check input signal is applied from the input signal inspection input application command 15 to the OR circuit OR2 to confirm the result of the re-closing operation. If an accident occurs in the system during automatic inspection of this reclosing circuit,
The holding circuit FFI, which maintains the application of the inspection input, is reset by the accident response signal using the inspection reset signal. This inspection 9 set signal e continues to be set 1161J for a certain period of time until the output of the final stage operated by the paper input command or the final cutoff command due to the application of manual inspection power returns to normal after the inspection input is canceled. On the other hand, in this reclosing circuit, when a system fault causes a tripping command from the device to take over the maintenance of the A series or B series, a reclosing start signal for a certain period of time H is given. If there is no off-delay timer T3, if the tripping command signal time tS runs out before the inspection reset duration time t14, re-closing cannot be started. The off-delay timer T3 is provided as an off-delay timer T5 for a certain period of time so that the re-closing activation signal is generated even after the inspection reset command is issued, and is used to ensure re-closing activation in response to a system failure interruption during the re-closing inspection. Further, the re-closing preparation incomplete condition extension timer T2 is also provided for the same reason as above, but it is set to a time limit in coordination with the inspection reset command.

The occurrence of problems in such a reclosed circuit with inspection will be explained. If the transmission line recloses at high speed,
The re-closing time of the circuit breaker is set to 0.25 seconds or more, depending on the time to erase the alarm at the fault point and the operational responsibility of the circuit breaker. The settling time of the on-delay timer T4 for reclosing no-voltage measurement is as follows:
It is considered as the value obtained by subtracting the no-load closing time of the circuit breaker from the no-voltage time of the transmission line. The no-load closing time of the circuit breaker itself varies depending on the type of circuit breaker, but if you are using a circuit breaker whose closing time is extremely long considering the worst case scenario, the no-load closing time of the circuit breaker itself will be On-delay timer T4
In some cases, the integer must be set to a short value. On-delay timer T4 for measuring reclosing no-voltage time
Depending on the relationship between this and the tripping command time t3 extended by the off-delay timer T3, a failure that results in final shutoff (O-CO) may occur in the nurse that should result in successful re-closing (O-C). obtain.

In Figure 3, if an accident occurs on the protected transmission line,
Tripping commands 14A and 14B are issued by the human series relay 8 or the B series relay 9, and the circuit breaker 5 is shut off. The tripping command 14A1 or 14B returns after the circuit breaker is shut off, but the signal a becomes "0" after being extended by the off-delay timer T3 for a time period of t5. On the other hand, the signal C becomes "0" after the CB is shut off. t! by the extended off-delay timer T2! The time limit was extended and the result was "0", meaning that preparations for re-closing the paper were not completed.

This problem is severe when there is a follow-up accident on another phase after one phase is shut off, and the signal a is further delayed, making it easier to detect the final shutoff and width when the preparation is incomplete. Also, a possible solution to this problem is to further extend t2 of signal C so that it is longer than the time when signal a becomes "0", but this problem can be eliminated. Prolonging is to prolong the uncompleted condition for re-closing preparation after shut-off, and if this timing is after the CB has been turned on, re-closing in the event of a permanent accident will be delayed, which is undesirable.

It is on the flow side. In FIG. 4, an AND circuit ANDIOI, 102 and a NOT circuit N0TIOI are added to the second ith' circuit, but the other circuits are the same. In Fig. 4, off-delay timers r, l; l for extending the cut-off command: These are necessary only during re-closing circuit inspection, and are not required during normal non-inspection, so re-closing circuit inspection command 150 Only when the conditions are met, the AND circuit ANDIOI makes use of the extension off-delay timer T3, and during non-inspection, the AND circuit AND102 uses the extension off-delay timer T3.
The above problem is solved by setting the input boot to "0" and not postponing the tripping command during normal times other than during inspection.
