Description
Technical field
The present invention relates to the guard method of a kind of 220kV intelligent substation list cover 110kV route protection stand-by heat.
Background technology
Along with the extensive foundation of intelligent substation, the popularization of new digital protective device and the requirement of more and more higher power supply reliability, bring challenge to traditional transforming plant protecting allocation plan and maintenance model.Especially, under guard mode maintenance model, protective device eliminates regular verification also may fault with serving burst.As a rule; the primary equipment of relevant protection and the correspondence of must stopping using when the enterprising line correlation work of protection, the process protective device defect of single cover configuration; tend causes the adjustment of operational mode, even causes the power failure of local, thus reduces power supply reliability.The application principle of present photo-electricity mutual-inductor and numerical protection; and protection adopts net to adopt net hop pattern all to provide a great convenience the alternative of former protection realizing stand-by heat protection, therefore becoming feasible a kind of pattern to the protection of intelligent substation stand-by heat is other for protection of the same type.
Summary of the invention
The invention provides the guard method of a kind of 220kV intelligent substation list cover 110kV route protection stand-by heat, it achieve stand-by heat route protection seamless switching when single cover route protection is stopped using, guarantee that corresponding primary equipment does not have a power failure.
Present invention employs following technical scheme: the guard method of a kind of 220kV intelligent substation list cover 110kV route protection stand-by heat, it comprises the following steps: step one, first realize dual to the list cover route protection preparing to stop using to run, stand-by heat line protective devices B definite value is switched to the definite value of the line protective devices A use preparing to stop using, by current/voltage corresponding for these cover line protective devices of input A and switching value, access in hot stand-by heat line protective devices B simultaneously; Stand-by heat line protective devices B tripping operation is outputed on primary equipment corresponding to access; Step 2, after checking stand-by heat protection sampling and normal operation, exits the route protection of former operation, simultaneously report regulation and control center, and line protective devices A is substituted by stand-by heat line protective devices B, and line protective devices A deactivates state; Step 3, line protective devices A out of service after end-of-job, then recovers loop and path; Step 4, check former line protective devices A sample and running status normal after, exit the route protection of former operation, simultaneously report regulation and control center, route protection A resumes operation, and stand-by heat route protection B deactivates state.
110kV circuit of the present invention is that net is when adopting net jumping mode, the stand-by heat line protective devices B set up in step one only needs with in All other routes protection access SV net and GOOSE net, increase stand-by heat protection B can gather All other routes protection input variable and jump the associated rights of respective switch and corresponding control word or soft pressing plate, need, by dropping into corresponding control word or pressing plate realizes protection dual configuration in configuration file, to need the definite value of preserving other all route protections simultaneously; Need to throw maintenance pressing plate to line protective devices A in step 2; In step 3, need the maintenance pressing plate exiting line protective devices A to be resumed operation by line protective devices A; The corresponding control word of relevant stand-by heat protection in configuration file or soft pressing plate is exited in step 4.
When 110kV circuit of the present invention is for directly adopting straight jumping mode, the stand-by heat line protective devices B that sets up needs to access an optical fiber from the intelligent merge cells of all 110kV circuits and intelligent terminal, all receive on the optical Fiber Closure of stand-by heat protection screen, at performing step for the moment, need the intelligent acess from line protective devices A on stand-by heat protective device, enable stand-by heat line protective devices B gather All other routes protection input variable and jump respective lines protective device A switch, be switched to the protection definite value of line protective devices A simultaneously thus realize protection dual configuration, at line protective devices A upslide maintenance pressing plate in step 2, in step 3, need the maintenance pressing plate exiting line protective devices A to be resumed operation by line protective devices A, in step 4, the optical fiber of circuit A merge cells and intelligent terminal is disconnected while exiting stand-by heat line protective devices B.
The present invention has following beneficial effect: after have employed above technical scheme; the route protection that the present invention can realize single cover configuration because of the other reasonses such as maintenance, fault stop using time; stand-by heat protection can be protected to inductive switch and circuit by the former protective device of the complete replacement of seamless switching under to inductive switch and circuit not power-off condition; avoid a large amount of primary equipment interruption durations; improve utilization rate of equipment and installations; reduce the professional indexs such as unplanned power failure ratio; improve the operational mode stability of network system, improve power supply reliability.
