摘要
为了克服静止同步补偿器(STATCOM)进行动态补偿时有功电流和无功电流的非线性、强耦合问题,建立了d-q坐标下STATCOM的数学模型,提出了非线性交叉解耦控制方法,利用MATLAB/SIMULINK仿真软件对系统进行了仿真,通过实验结果验证了静止同步补偿器在解耦控制下,有良好的无功电流跟踪特性,能有效改善电网质量。
In order to overcome nonlinear and coupled problems of active current and reactive current during the dynamic compensation of the static synchronous compensator（ STATCOM）, this paper presents a mathematical model to realize the nonlinear cross decoupling control for STATCOM in d-q coordinates.The system model is tested by using MATLAB / SIMULINK simulation software. The simulation results validate that the proposed cross decoupling control strategy performances well in tracking the reactive current aspect,and can improve the power quality effectively.
