摘要
变电站综自改造过程中,经常会发生直流接地、交流短路及交直流混接的现象,严重时将造成运行中的断路器跳闸,威胁着电力系统安全的稳定运行。文章总结了综自改造施工中的一些成功经验,提出了保证变电站安全运行的施工方法。
In the process of substation complex automation improvement, DC grounding, AC short circuit and AC - DC mixed wiring always occurred, and it may cause breaker trip in operation, thus threaten the safe and stable operation of electric power system. The paper summarizes some successful experience in the process of improving the complex automation system, and proposes constructing method to guarantee the safe operation of substation.
