The Nonlinear State PI Cntroller for the Excitation and Valve System of Generator Cooperate with SDR

利用非线性状态PI控制能直接对非线性不确定对象进行控制的特点 ,设计了发电机励磁、汽门与电阻挚动的非线性状态PI协调控制器。该协调控制器先根据等面积法则设计出电阻挚动的控制策略。然后将电阻挚动的制动作用视为发电机励磁与汽门协调控制的一个外部扰动 ,根据非线性状态PI控制器能将系统的外扰和不确定性等不确定因素进行实时补偿的特点 ,实现发电机励磁、汽门与电阻挚动的协调控制。仿真计算表明发电机励磁。

Because the nonlinear state PI control can directly deal with the uncertain nonlinear system,it is used to design the excitation and valve system of generator cooperate with SDR in this paper.Based on the EAC,the SDR control law is designed.Then the effect of SDR is treated as a disturbance to the excitation and valve control of generator.The disturbance is compensated in real time by the nonlinear state PI controller.The cooperative controller is accomplished.The simulation suggests that the cooperative controller can improve dynamic stability of power system effectively.
