摘　　要：某核电厂再循环冷却水系统在实践应用中遇到压力振荡典型问题,针对现场的实际工况,对振荡现象进行分析,提出不同工况下采用的两种PID参数策略。新的控制参数在再循环冷却水系统负荷切除的情况下,有很好的控制效果,并对PID控制系统提出展望,采用改进型PID控制算法,以自动适应不同工况下的负荷。Introduce selected DCS system and pressure control of main pipe in recirculated cooling water system.It meet pressure surge problem in application,when taking PID strategy in DCS system.Analyzing surging phenomenon,giving two PID strategies in different working condition.New control parameters get good effect as cutting systemic load in recirculated cooling water system.Taking ameliorated arithmetic to auto adjust the load in different condition.
