摘　　要：用直接反馈线性化控制理论，为ＳＶＣ设计了电压型非线性控制器，提出纯电压型ＳＶＣ控制器只能维持装设点电压，不能增加系统阻尼。对纯电压型ＳＶＣ非线性控制器进行了改进，设计出了既有维持ＳＶＣ装设点电压水平能力，又能显著增加系统阻尼，较为完善的信号调制型ＳＶＣ综合非线性控制器。对输电线上装设ＳＶＣ的单机无穷大系统进行了数字仿真，证明控制器具有良好的动态性能。所设计的两种控制器均实现了当地信号控制，并从理论上保证了控制器具有很好的鲁棒性。n this paper,the nonlinear voltage controller is designed for static var compensator (SVC) by employing the direct feedback linearization (DFL) theory. It is pointedout that SVC with only voltage control is able to maintain the voltage only at its locationbut can not produce additional damping torque to the system. By improvement of the nonlinear SVC voltage controller,a new signal modulation type synthetical nonlinear SVC controller has been developed. The synthetical nonlinear controller is able to produce additional Jamping torque obviously as well as maintain the voltage at SVC location. The digital simulation results support the analysis of the paper.
