Distribution master station FA anti-error verification method based on grid operation data

Abstract

The invention belongs to the field of feed line automation and particularly relates to a distribution master station FA anti-error verification method based on grid operation data. The method includesthe following steps of: (S1) embedding an FA anti-error verification function module as an independent module in a power distribution master station system; (S2) performing data sharing; (S3) performing fault diagnosis; and (S4) performing FA scheme verification and safety lockout. The method improves the safety and stability of the long-term operation of the FA function, deepens and perfects theFA function, and facilitates the operator to more fully understand the operating status of the feed line.

Description

technical field [0001] The invention belongs to the field of feeder automation, and in particular relates to an FA error-prevention verification method for a main power distribution station based on grid operation data. Background technique [0002] Feeder automation is the most basic and core application function of the distribution network. Specifically, in a system composed of circuit breakers and sectionalizers, when a permanent fault occurs in the feeder, it automatically locates the fault, and through the switch The action of the equipment realizes fault isolation; in the distribution network with ring network operation or ring network structure but open-loop operation, load transfer and power supply recovery in non-faulty areas are realized. [0003] After the feeder automation function of the power distribution master station is fully automatic and practical, the effect is not satisfactory. The main issues are: [0004] At present, there are very few units in China...

AI Technical Summary

Problems solved by technology

[0007] At present, the mainstream feeder automation processing flow is as follows: figure 2 as shown, figure 2 Although the flow shown can generate a set of troubleshooting solutions, due to the lack of a mechanism to check whether it is correct, once the solution is wrong, it may not be possible to isolate the faulty area from the entire network or fail to Restore power to all non-faulty areas, and may even cause new line faults, thus failing to deal with faults

In addition, the fault handling plan generated at this time is not accurate and complete enough to display the operating status and equipment information of the faulty feeder. It has an important impact, but it is not fully displayed in the fault handling plan. Therefore, use the FA anti-mischeck function to generate another set of fault handling plans for comparison with the plan generated by the master station system, and at the same time verify the operating status of the line and related equipment The information is necessary and feasible, and can play a good auxiliary role in the final effect of troubleshooting
