摘　　要：提出一种风电场中静止同步补偿器(static synchronous compensator,STATCOM)的非线性控制方法,以提高其动态性能。首先给出STATCOM的动态模型,然后应用输入-输出反馈线性化方法得到精确的线性化模型。将STATCOM应用到风电场中,比较加入STATCOM前后的电压变化情况,结果表明,输入-输出反馈线性化方法对STATCOM具有良好的控制性能,同时STATCOM的应用也提高了风电场的电能质量。A nonlinear control strategy for static synchronous compensator （STATCOM） configured in wind farm is proposed to improve its dynamic performance. Firstly, a dynamic model of STATCOM is given; then by use of input-output feedback linearization an accurate linear model of STATCOM is obtained. Applying STATCOM to wind farm and comparing the voltage variation before and after the STATCOM added, it is shown that the control strategy using input-output feedback linearization can implement satisfied control on STATCOM, meanwhile, the application of STATCOM can improve the power quality of wind farm.
