摘　　要：汽轮机调节系统是电厂关键系统。方家山核电厂采用法国Alstom开发的P320系统作为汽机调节的设备平台,其利用冗余的汽机调节控制器(STG)实现汽机控制,避免因控制器本身的问题导致机组瞬态,有效地提高机组可靠性。从现场实际出现的主/辅控制器间频繁切换问题入手,对STG主/辅控制器切换逻辑进行研究,找出引起该问题的根本原因,并对STG控制器切换逻辑加以优化。最终在确保冗余功能完整的前提下,解决了主/辅控制器间频繁切换的问题。The steam turbine governor system is a key system for nuclear power plant. QF plant turbine govern use P320 system of ALSTOM with redundant STG controllers. It can avoid transient caused by the controllers and improve the reliability of unit effectively. This paper according to the practical problem of master controller and standby controller frequently switching. By researching STG controller’s switching logic to find out the root cause of the problem and optimize STG controller’s switching logic. On the premise of ensuring the integrity redundancy function, solve the problem of frequently switching between master and standby STG controller.

关 键 词：汽轮机 P320 STG控制器 切换逻辑
