摘要
分析了动态电压恢复器DVR的复合控制策略,通过合理控制DVR的有功功率和无功功率的输出,实现了电源侧的高功率因数控制,并可消除电源电压的谐波含量,同时保证改善电压暂降/骤升的性能不受影响。仿真与实验结果验证了控制策略的有效可行。
Analysis was made to the complex control strategy of dynamic voltage restorer （DVR）. Via reasonable control of active and reactive power output of DVR, high power factor control at source side was realized, the harmonic components of source voltage could be eliminated and the improvement of voltage sags or swells was ensured. Simulation and experimental results verified the valid- ity and feasibility of the control strategy.
