This paper investigates the ability of correcting the power factor at the point of common coupling (PCC) of the source side using dynamic voltage restorer (DVR). By applying the phase angle control (PAC) method, the DVR compensating voltage will be injected with a specific phase angle and magnitude in series with the transmission line, which leads to a power factor angle shift of the resultant load voltage. As a result, the source voltage is always in phase with the source current under different load conditions, which means that the power factor correction is achieved at the PCC of the source side. A laboratorial prototype of the DVR is utilized to verify the proposed control algorithm. The experimental results validate that an approximate unity power factor can be maintained at the source side.

基于相角控制的三相DVR,在公共耦合点具有功率因数校正

本文研究了使用动态电压恢复器(DVR)校正源侧公共耦合(PCC)点处的功率因数的能力。通过应用相角控制(PAC)方法,将以与传输线串联的特定相角和幅度注入DVR补偿电压,这将导致合成负载电压的功率因数角偏移。结果,在不同的负载条件下,电源电压始终与电源电流同相,这意味着在电源侧的PCC上实现了功率因数校正。DVR的实验室原型用于验证所提出的控制算法。实验结果证明,可以在源侧保持近似单位功率因数。
