| 摘 要： | 针对传统DVR不能补偿持续电压跌落的问题,提出了一种新的动态电压恢复器(DynamicVoltageRe storer简称DVR)结构,采用易于控制的整流电路,将能量从电源提供给DVR,从而实现电压跌落的持续补偿。基于该DVR结构,分析了整个电路的控制方法。实验和仿真结果表明,该DVR可有效地解决电网电压的许多质量问题,保证敏感负载的电压稳定,满足电力负荷对电网电压质量的要求。

| Abstract: | A new topology of dynamic voltage restorer(DVR) is proposed to solve the continuous voltage sags, which can not be realized with the traditional DVR. The working mode and control strategy are introduced and analyzed.The simulation and experimentation shown that the presented DVR can constrain many kinds of voltage issue of power system, confirm the voltage stability of the sensitive load and satisfy the requirements of power loads for net voltage quality. |
