摘要
用扩展线性化方法设计了ＳＶＣ非线性控制器，较好地解决了电力系统固有非线性给设计带来的困难，并针对单机无穷大系统进行了数字仿真。分析和仿真结果表明：ＳＶＣ的非线性控制方式与ＳＶＣ的常规控制相比，可以显著地提高电力系统的稳定性。
A new approach of linearization of nonlinear system by extended linearization to the design of Static Var Compensator(SVC) is presented. It overcomes the difficulty in the design caused by strong nonlinearity of power system. Improvement of power system stability with SVC nonlinear controller is shown by the results of simulation on a single machine infinite bus systems.
