Summary of Research on Overvoltage Characteristics and Suppression Technology of Power Cable Operation

本文着重对比分析了近年来不同学者对电力电缆操作过电压的研究和仿真模型,总结了操作过电压产生的原因和影响因素,并详细介绍了空载线路合闸过电压和空载线路分闸过电压的研究成果。加装串联补偿电容器、合闸电阻或配置多组避雷器、增加线路分段数等措施可有效抑制开合闸过程产生的过电压。

This paper focuses on the comparative analysis of the research and simulation models of power cable overvoltage in different years, summarizes the mechanism of operating overvoltage, and introduces the overvoltage of the no-load line and the overvoltage of the no-load line. Research results. Adding series compensation capacitors, closing resistors or configuring multiple sets of arresters, increasing the number of line segments, etc. can effectively suppress the overvoltage generated during the opening and closing process.
