摘　　要：介绍了基于超导磁储能的动态电压恢复器的电路结构和补偿控制原理,提出了一种基于最佳实用性的电压补偿控制策略,该补偿控制策略能使动态电压恢复器在工作时输出较小的能量并保持高质量的补偿效果,并在MATLAB中模拟配电系统中负载端发生电压暂降时动态电压恢复器的工作情况,从仿真计算结果中能看出新型补偿策略能为装置带来更好的综合性能。This paper first by introduces the circuit structure and control principle of the dynamic voltage restorer （DVR） based on the superconducting magnetic energy storage （SMES）, and then presents an compensating control strategy based on the best practicability. This makes DVR output small energy and maintain high quality compensating effect. By building a signal machine infinite three-phase system in Matlab/Simulink, the paper simulates the operation of the DVR during the voltage sags. The voltage waveforms illustrate that the new compensating strategy has better compensating effect.
