变电站断路器更换方法的优化

Replacement Method Optimization of the Breakers in Substation

随着电力事业的飞速发展,许多变电站安装的老式一次设备需更换。断路器作为重要的一次设备,对于变电站的稳定运行具有重要作用,但传统的更换方法存在时间长、影响供电可靠性的问题。在保证工程质量的前提下,运用关键路径法对110 kV变电站断路器更换的施工方法进行了优化分析。应用实践表明,此方法可以极大地缩短工期,减少线路停电时间,有利于提高电力系统的稳定性和供电可靠性。

Along with rapid development of power technology, the old primary equipment in many substations is in the urgent needs of replacement. As a major primary equipment, the breaker plays an important role in stable operation of a substation. The traditional breaker replacement method has a time-consuming problem, affecting the power supply reliability. The breaker replacement method for 110 kV substations is optimized in this paper by using the key route method. It is proved that the optimized new method can significantly shorten the replacement time and reduce the power cut time of a transmission line, subsequently improving the stability of electric power system and the reliability of power supply.
