大型火电厂厂用电备用电源优化探讨

A Study on the Optimization of the Emergency Power Supply of Auxiliary Power in a Large Thermal Power Plant

针对某电厂失去备用电源,需进行厂用电改造的情况,采用不增加新的电气一次设备,只对二次控制回路进行优化的改造思路。对改造方法进行论证,并最终实现备用电源自投及倒换功能。

Because of the loss of the emergency power supply,the auxiliary power in a power plant needs to be renovated.The idea of optimizing the secondary control circuit instead of adding new primary electrical equipment is adopted.The scheme of renovation is verified and the function of automatic input and switching of the emergency power supply is realized.
