摘要(Abstract)：
对华能玉环电厂1000MW机组的循环水控制系统的改进措施进行了详细阐述。分析了循环水系统历次发生的不安全事件,改进了就地测量设备和联锁保护逻辑,以减少循泵误动或拒动的概率,提高了循环水系统运行的可靠性。
This paper particularly expatiates on improvement of cycle water control system in 1 000 MW unit of Huaneng Yuhuan Power Station.Based on analyzing all previous insecure faults of cycle water control system,local measure equipments and interlock protection logic are ameliorated.Thereby,probability of mis-operation can be decreased,and dependability of cycle water operation can be enhanced.
