针对电气系统中经常出现电压凹陷的现象，为了能够及时诊断出电压凹陷的情况，应用了新的检测算法—整流电压(RV)算法。利用TMS320C40板、滤波器和一些自动化软件等，对正常电压和由不同原因引起的凹陷电压信号进行采集，并根据电压波形以及相应的参数利用整流电压(RV)算法对各种电压信号进行计算、仿真等处理。大量实验结果表明，该算法不仅可以在极短的时间内有效地检测出电压凹陷情况，而且可以节省很大的存储空间和计算量。

For the voltage sag phenomenon of electrical system, and to be able to diagnose the situation promptly voltage sag, we propose a new detection algorithm: RV algorithm. In this study, TMS320C40 board, filter and some other softwares are used to collect some voltage signals which include normal voltage and voltage sag caused by different reasons, and the rectified voltage (RV) algorithm is applied to calculate, simulate and do some other treatment for a variety of voltage signals according to the voltage waveform and the corresponding parameters. Experimental results show that this algorithm can not only effectively detect the voltage sag conditions within a very short period of time, but also can save a lot of storage space and calculation.
