Background technology
In electric power system, in order to prevent misoperation of electrical equipment, need to carry out to current operation " five is anti-" locking inspection.Common " five is anti-" refers to and prevents recurrent five kinds of misoperation faults in the electric power system grid switching operation, and namely minute combination 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 is anti-" system of applying in electric power system at present is mainly used in the supervisory control system of transformer station, and the operation locking relation that directly defines between electric equipment by the attendant realizes.With " five the is anti-" difference in 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 relatively frequent." five anti-" in 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 the development of computer technology, the communication technology, increasing transformer station has realized no worker monitor.Automation system for the power network dispatching and electrical network centralized monitoring system have realized collecting 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
The present invention will solve technical problem and be to provide a kind of topological anti-misoperation system for power grid, can realize the operation locking between whole network equipment.
For solving the problems of the technologies described above, the invention provides a kind of topological anti-misoperation system for power grid, it is characterized in that, comprise following each functional module:
Data interface module: for from Automation System of Power Network and electrical network centralized control system, reading 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: process and the operational mode processing for electric network model; Electric network model comprises power equipment information, sign board information etc., and operational mode comprises the 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: for automatically carrying out the analysis of electric island and compartment analysis, adopt breadth-first search to generate electric island, in conjunction with the electric island state of the information such as generator, equivalent generator, earthing, sign board in island judgement; Take bus, circuit, transformer as the search border, automatically carry out compartment analysis, analysis result can realize preventing charged co-grounding switch, prevent from being with the ground connection combination switch, prevent from being with ground connection to close disconnecting link, prevent chargedly closing disconnecting link, prevent the anti-error function such as mistake drawing switch.
Anti-misoperation locking control module: be used to obtaining active user's operation, carry out different anti-misoperation locking logical process according to the operating equipment type, and result is returned to the user.
Aforesaid topological anti-misoperation system for power grid is characterized in that: the operating equipment type that described anti-misoperation locking control module is carried out the anti-misoperation locking logical process comprises: switching, the anti-error check of maintenance sign board of the anti-error and anti-mistaking of anti-error check, the our station of the anti-error check of the anti-error check of breaker operator, isolation switch operation, grounding switch operation.
Topological anti-misoperation system for power grid system principle of the present invention is: topological anti-misoperation system for power grid obtains 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 by interface.According to the annexation of electric equipment, carry out the network topology analysis, electrical network is divided into to charging zone, ground area and power supply interrupted district, realize simultaneously the compartment analysis of electrical network.According to electric island state and the interval, operating equipment place of operating equipment end points, automatically realize anti mis-closedown function.Because being carries out the network topology analysis automatically according to electric network model and real time operation mode, therefore, after electric network model changes, need not the user carry out the maintenance of anti-error rule.
Beneficial effect of the present invention: topological anti-misoperation system for power grid of the present invention adapts to the needs of dispatching of power netwoks development, according to the whole network model, carry out anti-misoperation locking control, can stop to greatest extent to dispatch the generation of misoperation, especially with ground connection operation disconnecting link, with the generation of the serious accidents such as ground connection console switch, charged co-grounding switch, for the safe operation that ensures electrical network, extremely important meaning is arranged.The variation of the automatic adaptive model of topological anti-misoperation system for power grid, need not user's service equipment between the operation locking relation, greatly alleviated maintenance workload, improved the intelligent level of operating efficiency and Automation System of Power Network.
The accompanying drawing explanation
Fig. 1 is topological anti-misoperation system for power grid Software for Design figure of the present invention;
Fig. 2 is topological anti-misoperation system for power grid workflow diagram of the present invention.
