摘　　要：动态电压恢复器(DVR)具有良好的动态性能,对电网电压波动有着很好的调节作用。提出了一种用于低压电网的新型动态电压恢复器,详细介绍了该DVR的工作原理,包括其主电路结构、检测算法和控制策略。并在仿真软件PSIM中建立了该DVR的详细模型,对电压波动情况下的DVR电压补偿过程进行仿真。仿真结果表明,该新型DVR具有较理想的动态特性和补偿效果。Dynamic voltage restorer （DVR） has good dynamic performance and well regulating function for grid voltage fluctuation. A new type DVR for distribution network is proposed in the paper. And the principle of the new DVR is introduced in detail, including its main circuit structure, detection algorithm and control strategy. Besides, the detailed DVR model is established in PSIM, and simulations of DVR voltage compensation with grid voltage fluctuation are carried on. Simulation results show that the new type DVR has ideal dynamic characteristic and compensation effect.
