Dynamic Voltage Restorer (DVR), for some important reasons, is utilized in Power Distribution for protecting loads especially critical loads against some power quality issues like sag, swell, harmonics and faults. Fast transient response for compensating voltage quality is an unavoidable factor. Different control topologies have been applied to this device. In this project, a DVR is deployed to preserve a critical load that is connected in parallel with the grid and A wind turbine. Several situations of power quality issues have been considered. The simulation results of a proposed system that has been implemented in MATLAB/Simulink show how DVR is effective for protecting loads.

用于保护混合电网的动态电压恢复器 (DVR)

出于某些重要原因，动态电压恢复器 (DVR) 在配电中用于保护负载，尤其是关键负载，防止出现一些电能质量问题，例如电压骤降、骤升、谐波和故障。用于补偿电压质量的快速瞬态响应是一个不可避免的因素。不同的控制拓扑已应用于该设备。在该项目中，部署了 DVR 以保护与电网和风力涡轮机并联连接的关键负载。已经考虑了电能质量问题的几种情况。已在 MATLAB/Simulink 中实施的建议系统的仿真结果显示了 DVR 如何有效地保护负载。
