基于扰动补偿的水电机组变参数频率控制策略
Disturbance-compensation-based variable-parameter frequency control strategy for hydropower units
摘要
Abstract
Traditional parameter control is difficult to adapt to the dynamic characteristics of the unit under multiple operating conditions,which restricts its full potential for regulation.Therefore,a variable parameter frequency control strategy for hydroelectric units based on disturbance compensation was proposed.By constructing a state space model of the regulation system and designing a load disturbance observer,effective estimation of the total disturbance of the system can be achieved.On this basis,the error minimization criterion was adopted to adaptively tune the control parameters,and the disturbance estimation was introduced into the control loop through a feedforward compensation mechanism to effectively suppress load disturbances.The simulation results show that the proposed method significantly improves the frequency regulation performance of the unit.Under load disturbances,the peak frequency response of the system is reduced by 25%compared to the parameter control method,and the regulation time is shortened by 3 4.5%,providing an effective technical approach for flexible regulation of hydropower units.关键词
