摘要
Abstract
General situation of substation outlet circuit breaker faults caused by lightning surge intrusion occurred in Guangdong region before the installation of outlet arrester is described, and it is clarified that the lightning surge intrusion protection for outlet circuit breakers during its reclosure must be reinforced, i.e., outlet arresters must be installed in front of outlet circuit breakers. Utilizing real-time＂ digital simulator （RTDS）, the overvoltage caused by lightning surge intrusion during the reclosure of outlet circuit breaker is simulated, and the effect of enhancing insulation level of transmission line and the protection result of adding outlet arresters are evaluated as well. Simulation results show that after outlet arrester is installed, although the insulation level of transmission line is strengthened considerably, dangerous lightning surge intrusion will not appear on outlet circuit breaker, thus the operating condition of lightning protection for substation can be effectively improved.关键词
