Substation secondary overhauling safety measure simulation rehearsal and anti-misoperation checking method

Abstract

The invention discloses a substation secondary overhauling safety measure simulation rehearsal and anti-misoperation checking method, which comprises the steps of 1, initializing model data, a secondary overhauling safety measure anti-misoperation rule base, a secondary circuit visualization unit and a front-end communication unit of a substation, and constructing an implementation environment; 2, confirming an overhauling operation object on a display interface in the secondary circuit visualization unit according to a secondary overhauling safety measure work task, and recognizing a rehearsed safety measure process type after rehearsal is confirmed to start; 3, starting to rehearse a safety measure item, performing anti-misoperation check diagnosis on the rehearsed safety measure item, if a diagnosis result passes, executing a rehearsal result, if the diagnosis result does not pass, reporting an error and a reason and prohibiting execution of the rehearsal; and 4, judging whether the rehearsal is over or not, if not, returning back to the step 3, if so, performing leak checking, then generating a simulation rehearsal report, storing and printing a safety measure ticket, restoring to the state before the rehearsal, and finally returning to the step 2.

Description

technical field [0001] The invention relates to the field of secondary maintenance of substations, in particular to a method for simulating and previewing safety measures for secondary maintenance of substations and checking for errors. Background technique [0002] With the continuous operation of smart substations, smart substation technology has brought a series of changes and good benefits to the construction of smart grids. The smart substation replaces the secondary cable with optical fiber and saves a lot of construction costs. The whole station is based on the SCD model file, and the secondary terminals and loops of the conventional substation become invisible virtual terminals and virtual loops. The GOOSE of the process layer is constructed through optical fibers. Communicate with SV to realize the original secondary physical loop function. Not only the addition of secondary equipment and network switches complicates the network structure, but also the actual physi...

AI Technical Summary

Problems solved by technology

Not only the increase of secondary equipment and network switches makes the network structure more complicated, but also the actual physical loop connection becomes a virtual loop, which virtually increases the difficulty and safety hazards for secondary maintenance

[0003] Many technologies that have been adopted so far, such as SCD model visualization, SCD control and secondary virtual circuit visualization, are all to help the secondary operation and maintenance of smart substations, and to a certain extent guarantee the implementation of secondary maintenance safety measures, but for The technical support for safety measures for secondary maintenance of smart substations is still insufficient, it is difficult to guarantee the correctness of safety measures for secondary maintenance, and misoperation is prone to occur
