摘要
针对500kV系统的断路器三相合闸操作过电压，建立了基于ATP-EMTP的仿真模型，对合闸电阻对断路器三相合闸过电压的影响进行了仿真分析。分析了合闸电阻对三相合闸最大过电压、姒统计过电压的影响，操作过电压的仿真计算对于断路器的参数选择和电网的绝缘配合计算具有一定的实际价值。
Abstract
In this paper,a model of 500kV circuit breaker based on ATP-EMTP is estabhshed,and the switching over-voltage is simulated.The effect of closing resistor to the maximum over-voltage and the 2% statistical over-voltage is studied.Theory calculation of switching over-voltage is important to parameter selection of circuit breaker and practical system security operation.
