FIG. 4 (a) is a distribution system diagram and FIG. 4 (b) is a switch disconnection timing. 3 is a timing chart showing As shown in Fig. 4 (a), the breaker (FCB) 1 and each switch 2a,
The distribution line is divided into multiple sections by 2b, 2c, and 2d. And each switch uses an automatic operation type switch that is always energized and has no voltage applied.
3b, 3c, and 3d are accident investigation devices installed at each switch position.
Consider a case where an accident occurs in the section between the switches 2b and 2c in the distribution line having the above configuration. In this case, the protection relay (not shown in the drawing) of the substation operates first due to an accident,
Circuit breaker 1 trips. Therefore, the power distribution line is cut off and each switch 2a, 2b, 2c, 2d is opened without voltage.
After that, when the reclosing relay (not shown in the drawing) of the substation operates for the purpose of detecting the accident section and the circuit breaker 1 is turned on, the accident investigator 3a that detects the charging on the power supply side is turned on (X time limit). After clocking, switch 2a is turned on. Then, the same operation is performed by the accident investigation device 3b, and the switch 2b is turned on.
Since the switch 2b is charged in the accident zone, the circuit breaker 1 trips again. At this time, the accident investigation device 3b which has issued the closing command to the switch 2b clocks the detection time period (time from charging to tripping), and the time is within a predetermined time (Y time period). Then, it is determined that this section is an accident section. Therefore, when power is re-transmitted again, the closing signal is not given to the switch (switch detecting the faulty section),
Hold open state.

うにしている。FIG. 2 shows an example of a logic circuit of a slave station logic section for judging accident detection information transmitted to the master station and battery control. In FIG. 2, T 1 is an on-delay timer, 3-8
1 is the auxiliary relay 3-8 described in FIG.
When the output V D of 3-3 has a distribution line voltage, V D is present and is excited, and when the distribution line is out of power, V D is not present and the excitation is released after a fixed time period. The time of T 1 is V due to a power outage of the distribution line.
After changes to V D No from D Yes, but to keep the longer settling than enough time to poll all slave stations from the master station. Further, AND of FIG. 2 is an AND circuit, FF is a memory circuit which is set by an input to S and is reset by an input to R, and T 2 is an on-delay timer which is used to judge the accident detection information transmitted to the master station. The output F of the failure detection unit 3-4 (F detection by detection of distribution line accident) is performed and the memory circuit FF is set.
After the failure is detected, even if the circuit breaker of the substation trips, the memory circuit FF continues to be set and is transmitted as it is to the master station as the accident detection information. The storage circuit FF is reset after the on-delay timer T 2 time limit by AND with the condition V D that the output of the storage circuit FF and the input power to the slave station are restored. The on-delay timer T 2 should be set longer than the time until the breaker on the substation side trips after the accident and the voltage detector 3-3 of the slave station judges that there is no input power (no V D ). It is a thing. This is to reliably transmit information to the master station when an accident occurs, and to automatically reset the memory circuit for accident detection information if the accident is restored before the circuit breaker trips (for example, instantaneous ground fault). I am trying to do it.

を論理部5-1 で判断する。FIG. 3 is a system operation flowchart for explaining the operation of the master station logic unit 5-1. Next, the operation of the embodiment of the present invention configured as described above will be described below.
The master station 5 constantly collects a large number of slave station information by polling via the logic section 5-1, the transmission section 5-2, and the transmission path 4, and monitors the switch state and the accident detection information. The condition of the circuit breaker is also monitored. In such a state, if an accident now occurs at point F of the distribution line, the fault detection unit 3-4 of the slave stations 3a and 3b detects the accident via the fault current detection CT6 and the F
Output detection. The slave station logic unit 3-6 stores the accident detection information at the F detection input as shown in FIG.
When polling comes from the master station 5 via 7, the accident detection information is transmitted. Even if the circuit breaker 1 trips due to the operation of a protection relay (not shown in the drawing) and the distribution line fails due to this accident detection information transmission, the power source of the battery 3-2 remains for a certain period of time (T 1 in Fig. 2). Correspondingly, since the accident is stored in the slave station as shown in FIG. 2, the accident detection information is surely transmitted from the slave station to the master station. Further, the auxiliary relay 3-8 is restored at a fixed time (T 1 in FIG. 2), the contact La is opened, and the load of the battery is cut off. Therefore, the battery is not over-discharged. In the master station 5, the logic section 5-1 judges the information of the slave station fetched by the transmission section 5-2.

る。In step S31 of FIG. 3, the logic unit 5-1 starts the judgment of the accident processing based on the trip information (CB trip) of the circuit breaker 1. In step S32, the transmitter 5-2,
Although information about each slave station is constantly collected by polling via the transmission line 4, information about each slave station after the breaker trip is collected. In step S33, the fault section is judged based on the information of each slave station by polling after the breaker trip. For example, when an accident occurs at point F in Figure 1, the slave station 3
In a and 3b, the fault detection unit 3-4 detects an accident and the slave station logic unit 3
At -6, it works like the logic in Figure 2. This accident detection information is returned to the master station through the slave station transmission unit 3-7 and the transmission line 4 even if the slave station power supply is cut off when the master station polls. Since the slave stations 3c and 3d are on the load side of the accident point F, the slave stations 3c and 3d return information that no accident has been detected at the time of polling from the master station.
Based on this information, in step S33, it is determined that there is an accident point between the switches 2b and 2c, and the accident section is determined. In step S34, it is determined whether or not the circuit breaker 1 is reclosed (CB closed) by the reclosing relay (not shown in the drawing) operation,
Prepare for subsequent processing. In step S35, on condition that the circuit breaker 1 is re-closed, a command to turn on the switch 2a is sent to the slave station 3a in order to transmit power to the sound section immediately before the fault section of the distribution line determined in step S33. Then switch 2a is turned on. Also, since the input power to the slave station 3a is activated by turning on the circuit breaker 1, the accident detection information of FIG. 2 stored in the slave station logic section 3-6 of the slave station 3a is V D conditioned condition. Resets after the T 2 time limit and returns to the normal operating state. When the switch 2a is turned on, the slave station 3b also performs the same movement.
If there is a loop point of another system on the load side from the accident point, it is naturally possible to make a decision to issue a closing command from the master station logic section 5-1 to the loop point and the switch of 2d. is there.

成することも容易に可能である。The logic of the accident memory shown in FIG. 2 is an example, and it is also possible to reset by sending a reset signal from the master station instead of the V D condition used for memory reset. Although the CB trip input information is used as the section determination start condition in FIG. 3, this may be replaced with feeder accident detection information. Also, in the above, because of the power transmission to the healthy section,
Although the master station issues a closing command to the slave station, the slave station has a built-in accident investigation function and after the circuit breaker is re-inserted, it is automatically closed by the slave station's accident investigation function. May issue a command to lock the accident investigation function of the switch slave station in contact with the accident section. Furthermore, FIG.
Then, the circuit breaker is reclosed by reclosing relay operation (CB closing).
After that, the switch closing process is performed, but instead of the reclosing by the reclosing relay operation of the circuit breaker, the master station may issue a reclosing command after the accident section is determined by the master station. In this case, by controlling the circuit breaker from the master station, the reclosing time can be greatly shortened. In addition,
Although the battery is described as a constant charge type, it can be easily configured as a non-chargeable type.

供給信頼度向上が図れる。As described above, according to the present invention, since the slave station is provided with the battery, the information of the slave station is transmitted to the parent station even if an accident occurs and the breaker on the substation side trips. Since it can be monitored at the station, the main station can determine the faulty section before the circuit breaker is turned on again. Therefore, after the circuit breaker is turned on, power can be transmitted to the healthy section by driving the slave station with a signal from the master station. Therefore, only one power failure of the distribution line is required, and the reliability of power supply can be significantly improved.
