Embodiment
Topological fail-safe device of the present invention; Sum up general five anti-rules and the electric island attitudes of five anti-rules and system are combined and form topology five anti-rules; When carrying out anti-false judgment according to these topology five anti-rules; If need understanding then the topological structure of system to be carried out the electric island type that topological analysis draws equipment two ends, operation front and back, whether correct according to the electric island type judgment device operation at equipment two ends, below in conjunction with specific embodiment and the present invention of accompanying drawing illustrated in detail.
Topological fail-safe device of the present invention; Comprise topology five anti-rule base, topological analysis module and anti-false judgment modules; The topological analysis module comprises that topological structure sets up module and electric island analysis module; Wherein, topology five is prevented the in store topology five anti-rules with five anti-rules and after electric island attitude combines of rule bases, and the topological structure of topological analysis module is set up module and accepted the topological structure that the staff sets up the request constructing system of topological structure; The system here can be that single transformer station also can be that the network that whole transformer stations form is the whole network; Before the operation of this device, the topological analysis module has been accepted staff user's request the topological structure of system has been set up, when there is the transformer station that increases newly in system; The staff goes into library button through node and sends request; Topological structure is set up the topological structure that topological structure that module sets up the topological structure of newly-increased transformer station and will increase transformer station newly incorporates system, and after this device operation, the anti-false judgment module is anti-ly regularly carried out anti-false judgment to operation of equipment in the system according to five of said five anti-rule bases; When needs are known electric island attitude; In following example, need know to branch operation the carrying out anti-false judgment of switch whether the electric island of branch operation front-rear switch either side becomes dead island by the island of living, at this moment; The anti-false judgment module is sent the request of topological analysis to the topological analysis module; Be when the anti-false judgment module sends request by topological five anti-rule decisions to the topological analysis module, the topological structure to system after the request of receiving of the electric island analysis module of topological analysis module carries out the electric island attitude that topological analysis obtains system, and the anti-false judgment module continues anti-false judgment is carried out in operation of equipment according to electric island attitude.
Electrical network is made up of several charged electric islands, and each electric island is made up of the electric component that links to each other between many buses and bus again.It is through circuit and transformer bus to be connected to be the island that electric island is analyzed; Wherein existing power supply has the island of load that the calculating meaning is just arranged again; Be called island alive; Otherwise be called dead island, if having earthing isolator to be in to close some equipment in position or the electric island to be provided with the ground connection indication plate, then this electric island is defined as the ground connection island.Electric operation in the electric power system mainly is the operation of switch, isolating switch and ground connection disconnecting link, and therefore five prevent it also being to these three kinds of operations of equipment, and it is anti-regular that five of these three kinds of equipment are prevented that the electric island attitude of regular coupling systems has formed topology five.
The topology five anti-rules of switch: because switch is the equipment that cut-offs with arc extinguishing ability, therefore five anti-rules to switch mainly are to prevent mistake deciliter switch and prevent to be with the ground connection cutter to run the pass jointly.
1) if. after switch broke off, the electric island of the arbitrary end node of switch became dead island by the island of living, and then points out user's cut-off switch possibly cause the equipment dead electricity; If after switch broke off, the electric island difference of switch ends node then pointed out user's cut-off switch possibly cause system splitting;
2). when switch either side isolating switch closed, when this closed an isolating switch both sides line and does not all have ground connection, switch can close a floodgate; Switch both sides isolating switch is all in a minute position, no matter whether the both sides isolating switch has ground connection, switch all can close a floodgate; Switch closes, if an end becomes island alive by dead island, then points out the user to charge to bus; Before switch closes, the electric island of switch ends node difference, prompt system is arranged side by side when then running the pass jointly.
The topology five anti-rules of isolating switch: prevent that with respect to five of switch five anti-more complicated of isolating switch prevent that band ground cutter from closing isolating switch and preventing two of on-load drawing isolating switches.
1) if. the arbitrary end node of isolating switch belongs to the ground connection island, does not then allow closing operation, in order to avoid band ground connection is closed isolating switch, sets switch that the isolating switch two ends are connected this moment and all is in and closes the position;
2). for the branch closing operation of isolating switch, judge whether it is the operation of falling the bus, if then must belong to the branch closing operation that same logic bus just can carry out isolating switch by bus;
3). for the branch closing operation of isolating switch, judge whether it is the operation of bypass isolating switch, if then have only by-pass switch just can carry out the branch closing operation of isolating switch in the separating brake position;
4). for the branch closing operation of isolating switch, judge whether it is the operation of bus contact isolating switch, if then must isolating switch one side bus isolating switch all just can carry out the branch closing operation of this isolating switch behind the separating brake;
5) if. isolating switch one end connects bus, circuit, transformer or load, and the other end connects switch and switch is closing the position, and perhaps the position all switch or other isolating switches and they is all being closed in two ends, then forbids the branch closing operation to isolating switch.
The topology five anti-rules of ground connection disconnecting link: through the system topological analysis; Electrical network is decomposed into island alive and ground connection island; If an end node of ground connection disconnecting link is for living island then forbid the closing operation of ground connection disconnecting link; In order to avoid charged splice grafting ground disconnecting link, suppose that the switch that the ground connection disconnecting link is connected is in closed position all the time this moment.
Above rule can change according to actual conditions, and when the staff has revised the contents of five anti-rules, five anti-rule bases are with in the five anti-rules of the content update of revising before unmodified.Be example below with the switch, the anti-false judgment process of switching manipulation is described, as shown in Figure 2, following to the anti-false judgment flow process of switch:
Electric island attitude before and after pair switching manipulation of step 204 and step 207 is analyzed, and this analyzes promptly is to be based upon topological structure to set up on the basis of the topological structure that module sets up.
Above-described embodiment of the present invention does not constitute the qualification to protection range of the present invention.Any modification of within spirit of the present invention and principle, being done, be equal to replacement and improvement etc., all should be included within the claim protection range of the present invention.
