摘要
研究了包含静止同步补偿器(static synchnorous compensator,简称STATCOM)的单机-无穷大电力系统中逆系统方法的应用。首先论述了逆系统方法的基本概念,然后给出了研究对象的数学模型。将同步补偿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,给出了包含STATCOM的单机-无穷大系统的三阶动态模型。此时,STATCOM的等效无功电流成为系统的一个控制变量。利用逆系统算法,逐步给出被控系统的逆系统、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。图2,参9。
The application of inverse system method of multivariable nonlinear system for ope-machine electrical power system is studied. The basic concept of inverse system method is introduce briefly and the mathematic model.for the plant is given. STATCOM is dealt with as a VAR current source and second order model for the generator is adopted. In the case, the third order controlling law,a-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. 2figs. ,9refs.
