| 摘 要： | 动态电压恢复器（DVR）是目前解决供电电压凹陷问题的有效装置，对电压凹陷特征量的准确检测是DVR正常运行的前提。本文基于同步坐标变换及软件锁相环（SPLL），提出了一种单相电压凹陷检测方法。该方法可以实现对单相电压凹陷幅值、起止时刻和相位跳变等特征量的动态检测。计算机仿真和DSP硬件实验表明，该方法适用于单相DVR的电压凹陷实时检测．

| Abstract: | At present dynamic voltage restorer(DVR) is an effective device to deal with the voltage sag.Exact detection of voltage sag characteristics is the precondition of DVR's normal working.Based on the transformation of synchronous coordinate transformation and SPLL,this paper proposes a single-phase voltage sag detection method.It could dynamically detect voltage sag characteristics including sag amplitude,sag duration and phase jump.The computer simulation and DSP based experimental results show that this method satisfies the requirement of real time voltage sag detection for single-phase DVR. |
