大容量链式静止同步补偿器(STATCOM)是典型非线性系统,其控制理论和算法复杂且抽象.本文根据链式STATCOM的有功-无功电流的动态数学模型,得剑非线性动态无功控制策略,利用双输入双输出线性化的控制方法,实现双输出变量解耦控制.仿真及实验研究表明,该链式STATCOM非线性双输出解耦控制器,在系统发生短路或大功率负载突变时具有良好的动态性能.

High power cascade static synchronous compensator(STATCOM) is a typical nonlinear system; the control theory and algorithm of which are complex and Abstract. Based on the dynamic mathematical model of the active and the reactive currents in a cascade STATCOM, we develop a nonlinear dynamic control strategy for the reactive power; and using the control method of two-input two-output linearization, we achieve the decoupling control for the output variables. The simulation and experimental results show that this nonlinear and two-output decoupling controller has a desirable dynamic performance, when a short circuit fault occurs or a high-power load abruptly changes.
