摘要

提出了取消线路断路器合闸电阻的两个判据;自编程序对12个500kV系统（简单网）进行了大量数值计算

发现线路绝缘故障率、MOA吸收能量均与系统第一串联谐振角频率（标幺值）有关;同时还研究了断路器合闸相位角分布规律、MOA的额定电压、线路绝缘水平等因素的影响。

Abstract

The criteria for cancelling closing resistors in 500kV line circuit breakers arepresented.Twelve simplified 500kV power systems were calculated.It is found that the transmission line risk of failure and the energy dissipated in MOAs are related to the first series resonant angular frequencey （per unit） of power systems.These factors including distribution of circuit breakers closing angle

rated voltage of MOA and the insulation level of transmission line are considered.
