摘　　要：将含SVC(taticvarcompensation)多机电力系统等值为两机系统,考虑等值两机系统在输出约束的条件下,应用backstepping方法设计了一种非线性SVC控制器。该SVC控制器不仅能够保留原系统的非线性特性,而且利用约束Lyapunov函数能够有效地控制等值两机系统的输出量在限制之内。仿真结果体现了设计方法的有效性。The equivalent of a multi-machine power system with SVC is a two-machine system.Considering the equivalent two-machine system under the output constraints,a nonlinear SVC controller is designed with the backstepping method.The SVC controller can not only preserve the nonlinear characteristics of the original system,but also use the constrained Lyapunov function to effectively control the output of the equivalent two-machine system within the limit.Simulation results demonstrate the effectiveness of the design method.
