摘　　要：静止同步补偿器(STATCOM)的控制策略很多,其中传统的PI控制在工程实际中应用最广泛,但它存在很多缺点,尤其是参数整定较麻烦,为此根据内模控制原理,对STATCOM的电流环采用前馈解耦控制策略,设计了STAT-COM的双闭环内模解耦控制器,设计原理简单,物理概念清晰,容易实现,而且能够达到良好的效果,最后经过实验验证了这种控制方法的良好性。STATCOM （static synchronous compensator） has many control strategies, and the most widely used in engineering practice is the conventional Pi control which has many shortcomings, especially the more difficult parameter tuning. Therefore, double closed -loop deeoupling controller based on internal model is designed for STATCOM, whose current loop adopts the feed-forward decoupling control strategy, The principle is simple and the physical concept is clear, what＇s more, it can a- chieve good results. In the end, the good performance of this control method is verified by the experiments.
