Abstract
This invention relates to 500kv transducer station area control network topological system, which defines repeated joint number of each network device to judge whether each device is connected; device controller collects electricity network device status data to computer system to judge whether the device has electricity to determine whether to process remote operations.
Description
Technical field
The present invention relates to network five-preventing system between a kind of 500kV transformer station station, interconnection network topology five-preventing system between the transformer station of particularly a kind of 500kV transformer station Region control.
Background technology
" five is anti-" block sytem is that electric power system is to preventing a kind of control system of back brake misoperation in power plant, the transformer station's power transmission and distribution process.It mainly is to limit: mistakenly entering charged chamber with technological means; Mistake drawing switch; On-load drawing disconnecting link; The charged ground cutter (hanging ground-wire) that closes; Band ground cutter (ground wire) closes a floodgate.
The back brake misoperation repeatedly repeats accidents causedly over the years in electric power system, be one of relation key of becoming distribution safety, also is that power industry is made a decision and thoroughly done away with the important step of potential safety hazard.Perfect organization and administration measure has been set up in electric power system aspect anti-misoperation, also successively released multiple mechanical lock, mechanical coding lock " five is anti-" block sytem and microcomputer " five is anti-" block sytem aspect technical measures.The field shows, although all kinds of " five is anti-" block sytem is preventing to have played important function aspect the misoperation, up to now till, all kinds of " five is anti-" block sytem remains in deficiency, does not reach the requirement of electric power system to " five is anti-" block sytem as yet.For this reason, according to the actual requirement of safety in production, need research new generation network five-defence block system.
The micro_computer five_proof locking is a kind of employing computer technology, is used for the device that high voltage switchgear prevents electric misoperation.At present the micro_computer five_proof system all can only realize five anti-in the our station, and the operation that relates to two or more 500kV transformer station all is to be judged whether and can be operated by the dispatcher according to the equipment state of dispatching patcher by the dispatcher, may exist misoperation to influence the potential safety hazard of electrical network because of personnel's erroneous judgement thus.500kV transformer station Region control network topology five-preventing system is for solving the above problem that exists, no longer adopt and conventional each equipment is write the correlated condition pattern to realize five-defence block, judge whether this equipment can be operated but adopt 500kV transformer station Region control electrical network network topology to analyze.
Summary of the invention
The technical problem to be solved in the present invention provides network topology five-preventing system between a kind of transformer station of 500kV electrical network Region control.
The technical solution used in the present invention is, in computer system, each grid equipment is defined unduplicated node number, whether interconnect to judge between each equipment, the status data of the grid equipment of equipment measurement and control instrument collection is sent to computer system, computer system is judged whether charged or on-load of grid equipment according to the data that collect, and determining whether can straighforward operation.
The invention has the beneficial effects as follows:
1. after carrying out network topology and analyzing the five-preventing system technology, artificial erroneous judgement is disconnected with reducing, the possibility of misoperation and mistuning degree, improves the fail safe of whole network system operation of equipment greatly.
2. this five-preventing system is just correct realizes five anti-in this transformer station, and has realized by the analysis of whole regional power grid network topology between the station of a plurality of transformer stations that five is anti-, especially relates to the five-prevention operation of interconnection between the station, guarantees the fail safe of operating.
Description of drawings
Fig. 1 is the five anti-key wiring diagrams of interconnection network topology between 500kV transformer station station.
Embodiment
The Regional Control Center network topology five-preventing system that the present invention relates to is realized topological analysis according to the electrical network figure, computer system is deposited among the database at each device type node number, dissimilar equipment has different node numbers, for example three-circuit transformer has three nodes, circuit breaker has two nodes, and the ground cutter has only a node.The node number of the node of two equipment that are connected in the database of computer system is the same, and all nodes all have unique, a unduplicated node number.After each node serial number, computer supervisory control system just can be judged the connection situation of each equipment by the situation that node connects.
In electrical network, each equipment carries out observing and controlling by the equipment measurement and control instrument, to gather the state of grid equipment.The equipment measurement and control instrument is connected with computer system, and the data that collect are sent to computer system.Computer system is according to the remote measurement of gathering and remote signalling position judgment equipment charged or on-load whether.According to preventing on-load drawing disconnecting link, prevent chargedly to close ground cutter (hanging ground-wire), preventing that band ground cutter (ground wire) three principles of closing a floodgate from judging whether this field apparatus can be operated.Because computer system can carry out observing and controlling to the grid equipment of a plurality of transformer stations, so this system can only not realize that five each transformer station in prevents, and can realize the five-defence block of interconnection equipment between a plurality of transformer stations.
Embodiment
Fig. 1 has explained interconnection network topology five anti-key wiring diagrams between 500kV transformer station station, 500kV transformer station Region control network topology five-preventing system is realized topological analysis according to the electrical network figure, can automatic defined node number at each device type system, such as three-circuit transformer three nodes are arranged, circuit breaker has two nodes, the ground cutter has only a node, and the node number of the node of two associated devices in database is the same, in the figure, the bus 500kV#1 at station, 500kV Nanning is connected with disconnecting link 50211, node number is 0001, disconnecting link 50211 links to each other with ground cutter 502117 with circuit breaker 5021, and node number is 0002, and the connected node of circuit breaker 5021 and ground cutter 502127 and disconnecting link No. 50221 is 0003, and the like, all nodes all have a node number.
This moment, computer supervisory control system just can be distinguished the connection situation of each equipment by the situation that node connects, such as circuit breaker 5,021 two nodes are arranged, be respectively 0002 and 0003, the one end links to each other with ground cutter 502127 that 0003 node is arranged and disconnecting link 50221 as can be known, and the other end links to each other with ground cutter 502117 with the disconnecting link 50211 that 0002 node is arranged.
The state information that computer system gathers whether each node is charged, whether equipment has load judges whether and can operate.For example, can know by the voltage of monitoring node 0002 whether it is charged, according to foregoingly preventing on-load drawing disconnecting link, preventing from chargedly to close ground cutter (hanging ground-wire), prevent the principle that band ground cutter (ground wire) closes a floodgate, under the charged situation of node 0002, the ground cutter 502117 that links to each other with this node can not be closed; Under the situation of ground cutter 502117 closures, disconnecting link 50211 can not close a floodgate.
