摘　　要：串联补偿是目前解决农网末端在用电高峰期欠压问题的有效方法。通过使用IGBT构建串联交流斩波器的电压补偿装置,并采用电压前馈和负载电流反馈相结合的数字方式进行控制,使电压稳定在220V左右。实验样机经过挂网测试,无谐波畸变,响应时间<40 ms。结果说明该装置具有良好的动态响应和稳定性,能够很好解决欠压问题,满足应用需求。Series compensation is the effective method to solve the voltage shortage problem in the electricity peak of rural power grid. This article uses the IGBT to set up the series AC-chopper voltage compensation device and take the combination of the feed-forward voltage and load current feedback in a digital mode and the voltage can stabilize about 220V. After the power network test, Prototype performs well, with no harmonic distortion, and the response time is less than 40ms. The Result shows that the device has good dynamic response and system stability, which can solve the problem of voltage shortage and satisfy the application requirement.
