摘　　要：某电厂由于低压厂用电系统原设计存在不足,增加了检修期间反复倒闸的操作量,降低了系统运行的可靠性和灵活性。通过后期逻辑优化、增加同步表实现了不停电切换,降低了倒闸操作量,提高了系统运行可靠性和灵活性。本文对此进行了较为详细阐述,供同行参考。Due to the design of low voltage auxiliary power system had insufficiency, a power plant increased with repeated switching operation quantity, reduced the system operation reliability and flexibility. Modifying late stages of logic and increasing synchronization table enables a power switch, which reduces the switching operation quantity, and improves system reliability and flexibility. Summary of the process can be used for reference in a similar the power plant technology personnel.

关 键 词：厂用电改造 倒闸操作 可靠性 灵活性
