SF6断路器投切66 kV并联电容器组仿真分析
Simulation Analysis of SF6 Circuit Breaker Switching 66 kV Shunt Capacitor Bank
摘要
Abstract
This paper aims to analyze the transient process of the 66 kV side switched capacitor bank in the 500 kV substation and compare various suppression methods by simulating five restriction measures under normal switching,asynchronous closing,single-phase reignition and two-phase reignition conditions,including series resistance,phase-controlled circuit breaker,L-R overvoltage protection device,RC resistance-capacitance protection device and metal oxide arrester.The suppression effect of these five measures is evaluated.The results show that these methods have varying degrees of suppression effects on overvoltage,and the advantages and disadvantages need to be considered comprehensively when selecting.Finally,it is recommended to use series resistance or phase-controlled circuit breaker for suppression,and select appropriate arrester wiring methods as protective measures.关键词
