摘要
阐述了基于空间矢量PWM动态电压恢复器(DVR)控制技术的基本原理,提出用锁相环技术闭环控制负荷侧电压的方法,建立了三相电压源空间矢量PWM控制模型。通过Matlab/Simulink软件对220 V配电系统发生三相和单相电压凹陷进行了仿真,仿真结果验证了所提出方法在系统发生单相和三相电压凹陷进行补偿时的有效性。
This paper introduces the basic principle of dynamic voltage restorer（DVR） based on space vector PWM,proposes to control load side voltage in closing loop by applying phase locking technique,establishes three-phase voltage source space vector PWM,and simulates three and single phase voltage sag in 220 V distribution system by Matlab/Simulink.Simulation result verifies the effectiveness of compensation due to single and three phase voltage sag.
