并联电容器组开断过电压改善措施

摘要

介绍加装金属氧化物避雷器限制电容器组操作过电压的方法，分未安装避雷器、在电容器首端安装避雷器及在电抗器首端安装避雷器三种模式对电容器过电压进行ATP-EMTP模型仿真分析。依据仿真分析电容器过电压幅值及分布，并为限制电容器组操作过电压提出有效的解决措施。%This paper will take the effect of adding metal oxide arrester, the method of limit over-voltage of capacitor Banks operating points not installed lightning arrester, the capacitor installed head end arrester and the reactor head end arrester three models of capacitor over voltage ATP - EMTP simulation analysis model. Based on the simulation analysis of capacitor over voltage amplitude and the distribution, and to put forward effective measures for solving limit over-voltage of capacitor set of operations.
