摘要
定义了水轮机调节系统受到大扰动(空载频率扰动、机组甩100%额定负荷和孤立电网运行)后动态过程的3种典型类型。通过水轮机调节系统仿真,详细分析了各个大扰动工况下3种类型的动态过程特性,并简要分析了动态过程特性类型与调速器比例—积分—微分(PID)参数的关系。
After undergoing large disturbances such as no-load frequency disturbance, abrupt rejecting rated load and out of synchronization, three typical dynamic process characteristics for hydraulic turbine regulating system are defined. Through the dynamic simulation of hydraulic turbine regulating system, each type dynafnic process characteristics under 3 large disturbances are analyzed in details. The relations between dynamic process types of hydraulic turbine regulating system and PID parameters of hydraulic turbine governor are briefly analyzed.
