摘　　要：为解决35 kV并联电容器开断时的重燃过电压问题,仿真分析了此类重燃过电压的基本特性,并指出现有避雷器配置在应对重燃现象时的局限性。随后通过研究金属氧化物限压器和电力电子阻尼型限压器两种过电压限制措施,基于多种工况下的仿真分析,明确了两种措施的过电压限制效果,并提出相应装置的总体设计原则和参数选取方法。In order to solve the problem of re-ignition overvoltage while switching of 35 kV shunt capacitors,it takes the simulation to analyze the basic characteristics of such re-ignition overvoltage,and presents the insufficiencies of the existing arresters in dealing of re-ignition phenomenon.It studies two overvoltage limiting measures of metal oxide varistor and power electronic damping limiters.Based on simulation of various working conditions,it clarifies the overvoltage limiting effects of these two measures,proposes the overall design principles and parameter selection methods of corresponding devices.
