PID控制在水电厂有功调节的应用

The Application of PID Controller in a Hydroelectric Power Station’s Active Power Regulation

本文主要讨论了PID控制在自动发电控制(AGC)和水轮机调速器中的应用,简要分析了调速器死区产生的原因及影响,重点阐述了脉冲调节及PID控制在水电站有功调节的具体实现方式。并针对大容量机组的负荷调节死区产生的负荷偏差提出优化解决方案,以及机组出力优化前后的对比。

This paper mainly discussed the application of PID control in automatic generation control(AGC)and water turbine governor,and briefly analyzed the causes and effects of the governor dead zone.What’s more,it also focused on the concrete realization method of the pulse regulation and PID control in the hydropower station.And the optimal solution is proposed for the load deviation caused by the load regulation of the large capacity unit,in this way the comparison of the output force optimization before and after the unit output is optimized.
