摘　　要：开化电厂为节省成本,主变采用升、降两用.#1发电机开关作为全厂唯一同期点,运行中曾出现发电机调频调压运行.结合垃圾发电实际情况,分析得出增加线路出线天汇3444开关为一个同期点的必要性和紧迫性.文章介绍了天汇3444开关同期合闸的实施方法及动作原理,以创造机组在调频调压下的合闸条件,提高了设备运行的经济性和安全性.In order to save costs,Kaihua Power Plant uses the main transformer for both raising and lowering,and the#1 generator switch is the only synchronization point in the whole plant.In fact,there has been frequency regulation and voltage regulation operation of the generator.Combined with the actual situation of garbage power generation,the necessity and urgency of increasing the outgoing line Tianhui 3444 switch as a synchronization point are analyzed,and the implementation method and action principle of the synchronization closing of Tianhui 3444 switch are introduced,so as to create the closing conditions of the unit under frequency regulation and voltage regulation,It improves the economy and safety of equipment operation.
