摘要
为了提高DVR补偿不平衡电压跌落的性能,将零稳态误差调节器用于电压外环以改善补偿效果。结合负荷电压外环、滤波电容电流内环的双闭环控制策略,对基于电压矢量控制的DVR进行了研究。应用MATLAB进行系统仿真,结果表明该方法具有良好的动态性能与补偿效果,验证了控制策略的正确性、优越性与有效性。
In order to increase the performance of compensation unbalanced voltage drop-off of a dynamic voltage restorer,a zero steady-state error controller is applied to the voltage outer loop to improve compensation effect.Combining the double closed loop control strategy of load voltage outer loop and filter capacitance current internal loop,the DVR based on the voltage vector control is analyzed.Use MATLAB to carry out the system simulation,the result shows the method has fine static performance and compensation effect and proves correctness,supriority and availability of the control strategy.
