摘要
Abstract
According to the problem of frequent regional faults of static var generator(SVG)devices in distribution networks,through statistical analysis of the operation data of 10 kV SVG in Liaoning area,combined with large-capacity true-type tests,it reproduces typical fault processes such as power module breakdown,communication link interruption and cooling system failure.It analyzes the causes of faults from multiple dimensions such as equipment design,heat dissipation system,communication reliability and operation and maintenance management.It proposes systematic improvement measures such as optimizing the three-proof process of power modu-les,redundant design of optical fiber communication,improvement of air cooling/water cooling systems,and standardization of opera-tion and maintenance procedures.It verifies the fault mechanism under the coupling effect of multiple factors through true-type testing and forms a targeted comprehensive solution.The results show that the proposed method can reduce the equipment failure rate,provi-ding support and practical basis for improving the reliable operation of SVG in the distribution network.关键词
