摘　　要：研究包含静止无功发生器SVG(Static VAR Generator)的单机-无穷大电力系统中逆系统方法的应用.首先给出研究对象的数学模型,将静止无功发生器作为一无功电流源来处理.发电机采用二阶简化模型,在此情形下,给出包含SVG的单机-无穷大系统的三阶动态模型.然后论述逆系统方法的基本概念.利用求逆算法,逐步给出系统的逆系统、反馈控制规律、α-阶积分逆系统、伪线性系统(积分解耦系统).对所得解耦系统,应用最优控制方法进行综合.仿真结果显示了此方法的有效性.The application of inverse system method of multivariable nonlinear system for one-machine electric power system with SVG is studied, the mathematic model for the plant is given and the basic concept of inverse system method is introduced briefly. Static VAR generator （SVG） is dealt with as a VAR current source and second order for the generator is adopted. In the case, the third order controlling law, α-order integral inverse system and integral decoupled system for the plant are derived step by step. For decoupled system obtained , its controller is synthesized with optimal control method. The simulation example shows the effectiveness of the method given by the paper.
