The plurality of relays include a VDD relay operating according to the voltage of the bus at the substation outside the reference voltage range, a bus protection differential (87B) relay operating according to the fault current of the bus, and the bus A busbar protection closed (86B) relay that operates according to the return of the plurality of connected breakers, a pressure (96P) relay that operates according to the secondary side fault current in the substation at the substation, and a neutral point ground reactor (at the substation in the substation) NGR), an overvoltage (59G) relay operating according to the disconnection, and a peripheral voltage differential (87T) relay operating according to the difference between the primary and secondary currents of the peripheral voltage in the substation, and the primary side of the peripheral voltage in the substation Depending on whether the secondary circuit breaker returns to the remote side, the peripheral voltage closed (86T) relay operates, and depending on the primary current of the secondary voltage or the overcurrent of the secondary side current in the substation. Including operating over-current 51 to the relay, and
The plurality of logic circuits, the VDD relay, the bus protection differential (87B) relay and bus protection closed (86B) relay input information of each operation, and outputs bus fault information that is one of the plurality of substation fault type information The operation information of each of the first logic circuit, the pressure (96P) relay, the overvoltage (59G) relay, the peripheral voltage differential (87T) relay, and the peripheral voltage closed (86T) relay is received, and among the plurality of substation failure type information A second logic circuit that outputs the one-in-one peripheral voltage NGR disconnection fault information, and information on the operation of each of the pressure (96P) relay, the peripheral voltage differential (87T) relay, the overcurrent (51) relay, and the peripheral voltage closing (86T) relay. And a third logic circuit for receiving the overvoltage fault current information of the peripheral voltage, which is one of the fault type information of the plurality of substations, and adaptive fault recovery method according to the fault type of the substation.
The method of claim 9,
The method further includes receiving gas pressure information of each of the plurality of gas insulated switchgears (GIS) of the substation and on / off state information of each of the plurality of disconnectors of the substation,
The step of applying to each of the plurality of logic circuits further applies input gas pressure information and input on / off state information to the plurality of logic circuits,
In the generating of the substation recovery procedure information, the position information of the gas insulated switchgear having gas pressure information outside the reference gas pressure range among the gas pressure information of each of the plurality of gas insulated switchgears, and on / off of each of the plurality of disconnectors An adaptive failure recovery method according to a failure type of a substation that generates substation recovery procedure information by applying at least one of position information of a disconnector having on / off status information different from a reference on / off status information among status information.
A computer-readable recording medium in which instructions for executing by the processor each step of the method according to any one of claims 9 to 11 are recorded.
