摘要

阐述了有源功率因数校正(APFC)技术的工作原理。为了消除动态电压恢复器直流储能单元充电过程中的谐波和无功电流，将APFC技术引入动态电压恢复器直流储能单元的电压控制中，提出了DVR直流储能单元的数字电压控制算法，给出了电压控制器和电流控制器的设计方法。仿真结果表明，采用APFC技术可以有效地消除DVR充电电流中的谐波和无功电流，提高直流储能单元的电压稳定性和动态响应。

Digital voltage control for DC energy storage unit of dynamic voltage restorer

The working principle of active power factor correction (APFC) technology is expounded. To eliminate harmonics and reactive current during the charging process of DC energy storage unit of the dynamic voltage restorer (DVR), leading APFC technology into the voltage control of DC energy storage unit of dynamic voltage restorer, the digital voltage control algorithm for DC energy storage unit of DVR is proposed and the design approach for voltage controller and current controller is given. Simulation results show that by use of APFC technology the harmonics and reactive current in charging current of DVR can be actively eliminated and both voltage stability and dynamic response of DC energy storage unit can be improved.
