摘要

本文提出了一种动态电压恢复器(DVR)，用于配电系统中跌落和膨胀从10%到90%的补偿和功率因数校正。由于故障的补偿时间有限，导致电压降扩散到电力系统的敏感负载上，因此电压跌落并不总是可以预防的。DVR模型基于电压源变换器(VSC)方案进行电压补偿，因为存在0.1至0.9 pu的幅度下降和1.1至1.9 pu的幅度膨胀。通过MATLAB和Simulink®对仿真结果进行了验证。

Sags and swells compensation and power factor correction using a dynamic voltage restorer in distribution systems

In this paper, a Dynamic Voltage Restorer (DVR) for the sags and swells compensation from 10% to 90% and power factor correction in distribution systems is proposed. The voltage sags are not always possible to prevent due to the finite time compensation of faults that causes voltage drops to spread to sensitive loads in electrical systems. The DVR model is based on a Voltage Source Converter (VSC) scheme for voltage compensation due to the presence of sags of amplitude ranging from 0.1 pu to 0.9 pu and swells with amplitude from 1.1 pu to 1.9 pu. The results obtained through MATLAB & Simulink® are verified.
