Embodiment
The utility model discloses a kind of centralized protection supervisory equipment of 3/2 wiring, including three CPU cards, difference
For process layer interface CPU card, protection CPU card and station level communication cpu plug-in unit, current intelligent substation device number is solved
Amount is more, the problem of operation maintenance is difficult.
The utility model is described in further detail below in conjunction with the accompanying drawings.
A kind of centralized protection supervisory equipment of 3/2 wiring, its core concept be by it is multiple interval breakers, disconnecting link, CT,
PT accesses integrating device as entirety, by all information unifications, and realizes the basic training such as protection observing and controlling based on this partial information
Energy；The protection domain that centralized protection supervisory equipment is specifically covered is as shown in figure 1, including breaker protection, breaker observing and controlling, line
Drive test control, route protection and main transformer backup protection etc.；For needing the main transformer differential main protection of many side information real by other devices
It is existing.
The device relies on the communication network of intelligent substation, the reception and transmission of data needed for realizing.Wherein Current Voltage
Sampled data is sent to integrating device, intelligent terminal by process-level network by switching value by combining unit by process-level network
Signal is sent to integrating device.After the completion of integrating device is handled by correlation module, trip signal is led to transformer station by network
Intelligent terminal is issued with event (GOOSE) message, so as to realize tripping operation.It is illustrated in figure 2 the utility model and device is provided
Data flow schematic diagram.For example：The sampled values such as two breakers of collection related electric current, voltage are needed during 1 protection act of circuit
Information, circuit breaker position information, above- mentioned information are forwarded to integrating device by combining unit and intelligent terminal by interchanger, integrated
The protection module of circuit 1 of device sends switch trip order and is forwarded to the related intelligence of breaker eventually by interchanger after having handled
End, then realizes the tripping of switch.
As shown in figure 3, the utility model builds the framework of centralization protection observing and controlling using 3 CPU cards.Process layer interface
CPU plug-in units are main to provide redundancy 1000M optical Ethernet process bus interfaces as process bus processing unit, complete SV data
