摘要
针对链式静止同步补偿器(STATCOM)的非线性、多变量高阶、强耦合特点,建立两相旋转d,q坐标系下链式STATCOM数学模型,应用内模控制原理,设计解耦控制算法,给出解耦控制模型,并进行样机验证。结果表明,应用内模原理解耦,在a,b,c和d,q坐标系下链式STATCOM三相电流控制具有较好的跟踪性能和控制精度,实现了较为理想的电流补偿效果。
As static synchronous compensator（STATCOM） is a high order complicate system with parameter variable, nonlinear,strong coupling and muhivariable ,mathematical model of cascade STATCOM in d,q coordinates is de- duced.Decoupling control algorithm is designed,decoupling model of cascade STATCOM is given by internal model control principle, experiments are also given.The results show that with internal model control, three-phase currents of cascade STATCOM have good tracking performance and control precision both in a, b, c coordinates and in d, q coor- dinates, and also achieve excellent current compensation results.
