Background technology
[0002] in electric power system,, need carry out " five is anti-" locking inspection in order to prevent misoperation of electrical equipment to current operation.Common " five is anti-" is meant and prevents recurrent five kinds of misoperation faults in the electric power system grid switching operation, and promptly deciliter switch, on-load drawing isolating switch, band ground cutter close isolating switch, charged ground cutter (hanging earthing conductor) and the mistakenly entering charged chamber of closing by mistake.
" five the is anti-" system that uses in the electric power system at present is mainly used in the supervisory control system of transformer station, directly defines operation locking between electric equipment through the attendant and concerns and realize.With " five the is anti-" difference in the monitoring system of electric substation, in automation system for the power network dispatching and in the electrical network centralized monitoring system, not only number of devices is huge, and the equipment mobility is also frequent relatively." five anti-" in the monitoring system of electric substation can only realize the operation locking between this transformer station internal unit in addition, can't realize the operation locking with the distance station equipment room, and this are even more important when line maintenance.
Along with computer technology, development of Communication Technique, increasing transformer station has realized no worker monitor.Automation system for the power network dispatching and electrical network centralized monitoring system have realized compiling of this area model and real time operation mode, for the construction of realization based on the anti-error system of power network topology lays a solid foundation.
Summary of the invention
Technical problem that the present invention will solve provides a kind of power network topology anti-error system, can realize the operation locking between whole network equipment.
For solving the problems of the technologies described above, the present invention provides a kind of power network topology anti-error system, it is characterized in that, comprises following each functional module:
Data interface module: be used for from grid automation system and electrical network centralized control system read electric network model and power system operating mode, obtain the current verification of user operation, the anti-false judgment result is returned to the user;
Data processing module: be used for electric network model processing and operational mode and handle; Electric network model comprises power equipment information, sign board information etc., and operational mode comprises information such as remote measurement, remote signalling.Electric network model and operational mode information are data of the present invention bases.
Network topology analysis module: be used for carrying out automatically electric island and analyze and compartment analysis, adopt the BFS algorithm to generate electric island, judge electric island attitude in conjunction with information such as generator, equivalent generator, ground connection cutter, sign board in the island; With bus, circuit, transformer is the search border; Automatically carry out compartment analysis, analysis result can realize preventing charged splice grafting ground disconnecting link, prevent to be with ground connection to run the pass jointly, prevent to be with ground connection to close disconnecting link, prevent chargedly to close disconnecting link, prevent anti-error function such as mistake drawing switch.
Anti-misoperation locking control module: be used to obtain active user's operation, carry out different anti-misoperation locking logical process, and the result is returned to the user according to the operating equipment type.
Aforesaid power network topology anti-error system is characterized in that: the operating equipment type that said anti-misoperation locking control module is carried out the anti-misoperation locking logical process comprises: anti-error check, the anti-error check of ground connection switch operation of the anti-error check of breaker operator, isolation switch operation, our station is anti-error and the switching of anti-mistaking, the anti-error check of maintenance sign board.
Power network topology anti-error system system design principle of the present invention is: the power network topology anti-error system obtains the model and the real time operation mode information of current electrical network from automation system for the power network dispatching or electrical network centralized monitoring system through interface.Annexation according to electric equipment is carried out the network topology analysis, and electrical network is divided into charging zone, ground area and power supply interrupted district, realizes the compartment analysis of electrical network simultaneously.Anti mis-closedown function is realized at electric island attitude and operating equipment place according to the operating equipment end points at interval automatically.Owing to be to carry out the network topology analysis automatically, therefore after electric network model changes, need not the user carry out the maintenance of anti-error rule according to electric network model and real time operation mode.
Beneficial effect of the present invention: power network topology anti-error system of the present invention adapts to the needs of dispatching of power netwoks development; Carry out anti-misoperation locking control according to the whole network model; Can stop to dispatch the generation of misoperation to greatest extent; Especially with the generation of serious accidents such as ground connection operation disconnecting link, band ground connection console switch, charged splice grafting ground disconnecting link, extremely important meaning is arranged for the safe operation that ensures electrical network.The variation of the automatic adaptive model of power network topology anti-error system, need not user's service equipment between the operation locking relation, alleviated maintenance workload greatly, improved the intelligent level of operating efficiency and grid automation system.
