摘要(Abstract)：

对乐清发电厂600 MW机组投产后因热控系统原因引起的机组跳闸故障进行归类分析,从设备、控制逻辑、技术管理等方面提出了改进方法,在完善热控系统控制逻辑的同时,制定有效的管理措施,以减少热控原因引起的机组跳闸次数。
This paper performs the classified analysis on the unit trip faults caused by thermal control system faults after 600 MW units were put into operation in Yueqing Power Plant.The improvement methods are put forward in terms of equipments,control logic and technical management.While enhancing control logic of thermal control system,it develops the effective management measures to reduce unit trips caused by thermal control fault.
