Description
Technical field
The utility model relates to relay protection of power system and automatics field, more particular words it, the utility model relates to a kind of GOOSE message for the relaying protection digital improvement/switching value conversion equipment.
Background technology
At present, the traditional relay protection device utilizes the secondary cable transmission of electric signals, and digital relay protection device is by optical cable transmission GOOSE message protocol.The digital improvement project of operation electric substation; if according to traditional relaying protection modification scheme; stop successively to use as a servant the primary equipments such as circuit (main transformer, switch); implement the relay protection device digital improvement; the inevitable relay protection device that has simultaneously not transformation and transformed; not the traditional circuit protection, switch protection, bus differential protection, main transformer protection of transformation how with the digital protection reliable fit of having transformed, become the Focal point and difficult point in the relaying protection digital improvement.
For example the 500kV system protection can carry out intellectualized reconstruction by string, first synchronous transformation switch protection and circuit (main transformer) protection, and in string, equipment can synchronously be realized the GOOSE communication.But the 500kV bus differential protection can not be out of service for a long time; only after all the transformation of limit switch protection and intelligent end device is completed; the digitlization bus differential protection just can put into operation, realizes that the digitlization bus bar differential prptection operation jumps the limit switch, starts the limit malfunctioning switch and the limit malfunctioning switch starts the functions such as bus differential protection.Must guarantee traditional bus differential protection reliability service before this, but traditional bus differential protection can't be directly and digitlization limit switch protection and intelligent end device communication.In like manner, if first transform bus differential protection, digitized bus differential protection can't be directly and the switching protective device communication of traditional limit.
And for example; the 220kV system protection is first by the interval transformation that has a power failure successively; but the 220kV bus differential protection can not be out of service for a long time; only after all 220kV circuit (mother, segmentation etc.) protection transformation is completed; the digitlization bus differential protection just can put into operation, realizes that letter is far jumped/stopped to the tripping operation of 220kV bus bar differential prptection operation, startup circuit, malfunctioning switch starts the functions such as bus differential protection.Must guarantee traditional bus differential protection reliability service before this, but traditional bus differential protection can't be directly and digitlization route protection and intelligent end device communication.In like manner, if first transform bus differential protection, digitized bus differential protection can't be directly and traditional circuit (mother, segmentation etc.) protective device communication.
For another example, though the 500kV main transformer protection is transformed with the device synchronization of affiliated string, realize the synchronous communication of main transformer protection and be connected 500kV switch protection and intelligent end device, but can't synchronously realize the communication of following functions: 220kV bus connection switch, positive mother partition switch, secondary mother partition switch are jumped in main transformer 220kV backup protection; This change 220kV switch is jumped in the main transformer protection action, if malfunctioning switch starts the 220kV bus differential protection; The 220kV bus bar differential prptection operation is jumped main transformer 220kV switch, jumps three side switches if malfunctioning switch joins by main transformer protection.In like manner, if the advanced row of 220kV system equipment digital improvement also can't synchronously be realized above-mentioned functions.
At present, the feasible 500kV transformer station digital improvement scheme of entirely standing has following two:
Scheme one, the primary equipment of the same electric pressure of entirely standing are stopped simultaneously labour and are carried out digital improvement and debugging, go into operation;
Scheme two, the two cover protections transformation separately respectively of dual configuration, the full station first set protection of stopping using simultaneously accesses corresponding electric current, voltage, switching value, carries out transmission test, puts into operation after load test is correct; Then full station the second cover of stopping using is protected, and accesses corresponding electric current, voltage, switching value, puts into operation after test is correct.
Scheme one defective, the primary equipment of the same electric pressure of entirely standing are stopped labour simultaneously, have destroyed the integrality of electric power system, must consider all powerup issues of load, reduce power supply reliability.At first, the load that can shift goes to other electric substation's power supply, but can cause that system loses stand-by power supply or open loop operation, has reduced power supply reliability.Secondly, untransferable load need to have a power failure on line steel tower outside this electric substation's enclosure wall and overlap, and needs again after project is completed again overlap by the former mode of connection, has increased workload, has increased security risk, has also reduced power supply reliability simultaneously.The 3rd, may lose institute's electricity consumption in the station after full cut-off, protective device debugging and power, mains lighting supply need externally fed.
Scheme two defectives, the primary equipment of entirely standing will have a power failure twice, and the operation workload is large, and the handling safety risk is high; The long-time single cover protection operation of 500kV system, system safety operation is very risky; The configuration of tradition transformer substation switch failure protection substance when the first set protection is transformed in advance, need to disconnect secondary circuit relevant to the first set protection in switch protection, guarantee simultaneously that the loop relevant with the second cover protection contacts reliable and guarantee correct; When the second cover intelligent terminal wiring and debugging,, easily go to the wrong way the interval, touch operational outfit by mistake at a distance of too near with first set protection (intelligent terminal), security risk is larger.
