FIG. 4 (a) is a power distribution system diagram, and FIG. 4 (b) is the timing of switch disconnection. FIG. As shown in Fig. 4 (a), the circuit breaker (FCB) 1 and each switch 2a,
The distribution line is divided into a plurality of sections by 2b, 2c, and 2d. Each switch uses an automatic operation type switch with a constant excitation and no voltage release method.
3b, 3c and 3d are accident detectors 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 substation protection relay (omitted in the drawing) will be activated first due to the accident,
Circuit breaker 1 trips. Accordingly, the power distribution line is interrupted, and the switches 2a, 2b, 2c, 2d are released without voltage.
Thereafter, the reclosing relay (not shown in the drawing) of the substation is operated for the purpose of detecting an accident section, and the circuit breaker 1 is turned on. When the charge detector on the power supply side is detected, the accident detector 3a is turned on (X time period). After clocking, the switch 2a is turned on. Next, the same operation is performed by the accident detector 3b, and the switch 2b is turned on.
The closing of the switch 2b is a charge in the accident section, so the circuit breaker 1 trips again. At this time, the accident detector 3b that issues the closing command to the switch 2b clocks a detection time period (time from charging to tripping), and the time is within a predetermined time (Y time period). It is determined that this section is an accident section. Therefore, at the time of re-power transmission, the switch is not given an ON signal to the switch concerned (switch that detected the accident section),
Hold open.

Is the auxiliary relay 3-8 described with reference to FIG.
The output V D 3-3 is excited becomes V D Yes when the distribution line voltage Yes, during distribution line power failure are those certain time period after the excitation is solved becomes V D no. Timed T 1 is V in the power failure 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, the AND of FIG. 2 AND circuit, FF storage circuit for resetting the input to the set, R at the input to the S, T 2 is determined in the fault detection information to be transmitted to the master station in On delay timer, Fig. 1 This is performed by the output F of the failure detection unit 3-4 (detection of F in distribution line fault detection) and sets the storage circuit FF.

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 section 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 line 4, and monitors the state of the switch and the accident detection information. The condition of the circuit breaker is also monitored. In such a state, if an accident occurs at the point F of the distribution line, the failure detection units 3-4 of the slave stations 3a and 3b detect the accident via the accident current detection CT6 and
Output detection. The slave station logic unit 3-6 stores the accident detection information by the F detection input as shown in FIG.
When the polling is received from the master station 5 via 7, the accident detection information is transmitted. This accident detection information transmission is performed even if the circuit breaker 1 of the substation trips due to the operation of the protection relay (omitted in the drawing) and the power distribution line is interrupted, and the power of the battery 3-2 is maintained for a certain time (T 1 in FIG. 2) Since the accident is stored in the slave station as shown in FIG. 2, the accident detection information is reliably transmitted from the slave station to the master station. Further, the contact La becomes open by the auxiliary relay 3-8 is restored in a predetermined time (T 1 in FIG. 2), the load on the battery is turned off, the battery will not be over-discharged. In the master station 5, the information of the slave station fetched by the transmission section 5-2 is judged by the logic section 5-1.

る。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 S31 of FIG. In step S32, the transmission unit 5-2 first,
Although polling is always performed via the transmission line 4 to collect information on each slave station, information on each slave station after tripping the circuit breaker is collected. In step S33, an accident section is determined based on information of each slave station by polling after the circuit breaker trip. For example, when an accident occurs at point F in FIG.
In a and 3b, the fault detection unit 3-4 detects an accident, and the
-6 acts like the logic in FIG. Even if the power of the slave station is lost when polling is received from the master station, the accident detection information is returned to the master station via the slave station transmission section 3-7 and the transmission path 4. The slave stations 3c and 3d return information on which the fault is not detected due to the load side of the fault point F at the time of polling from the master station.
In step S33 based on these information, it is determined that there is an accident point between the switches 2b and 2c, and an accident section is determined. At step S34, it is determined whether or not the circuit breaker 1 has been turned on again (CB turned on) by a reclosing relay (omitted in the drawing) operation.
Preparation for the subsequent processing is performed. In step S35, on the condition that the circuit breaker 1 is turned on again, a command to turn on the switch 2a is sent to the slave station 3a in order to transmit power to a healthy section immediately before the fault section of the distribution line determined in step S33. Then switch 2a is turned on. Further, since the live input power to the child station 3a by the circuit breaker 1 is turned on, the fault detection information in FIG. 2 which is stored in the slave station logic unit 3-6 of the slave station 3a, V D Yes Condition in it is reset after T 2 teaching units, return to a normal operating state. When the switch 2a is turned on, the slave station 3b performs the same operation.
Also, if there is a loop point of another system on the load side from the accident point, it is of course possible to make a decision to issue a closing command from the logic unit 5-1 of the master station to the loop point and the 2d switch. is there.

成することも容易に可能である。[0009] Logic of the accident memory shown in FIG. 2 is an example, it is possible to reset by sending a reset signal from the master station, in place of the condition of V D being used for the storage 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. In the above, for power transmission to healthy sections,
When the master station issues an injection command to the slave station, it has a built-in accident detection function as a function of the slave station, and after restarting the circuit breaker, it automatically turns on with the accident detection function of the slave station. May issue a command to lock the accident investigation function of the switch slave station in contact with the accident section. Further, FIG.
Then, the circuit breaker is turned on again by the reclosing relay operation (CB turning on)
After that, the switch closing process is performed. However, instead of re-closing by the reclosing relay operation of the circuit breaker, a re-closing command may be issued from the master station after determining the accident section in the master station. In this case, by controlling the circuit breaker from the master station, the re-closing time can be greatly reduced. In addition,
Although the battery is described as being always charged, it is easily possible to configure it as a non-rechargeable battery.

供給信頼度向上が図れる。As described above, according to the present invention, the provision of the battery in the slave station allows the information of the slave station to be mastered even when an accident occurs and the circuit breaker on the substation side trips. Since monitoring can be performed by the station, the master station can determine the accident section before the circuit breaker is turned on again. For this reason, after turning on the circuit breaker, power transmission to the healthy section can be performed by driving the slave station with a signal from the master station. Therefore, only one power outage of the distribution line is required, and the power supply reliability can be significantly improved.
