摘要
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.
