摘　　要：电压暂降已成为电能质量分析中的重点问题,快速而准确地检测出电压暂降的特征值,是电压暂降有效补偿的前提。阐述瞬时电压dq变换、基于电压求导的dq变换、延时90°的αβ-dq变换和基于电压求导的αβ-dq变换共4种检测方法,通过Matlab/Simulink仿真软件对4种检测算法进行仿真,并对仿真结果进行分析,得到更适合应用于动态电压恢复器(DVR)的检测算法。Voltage sag has become an important problem in power quality analysis, Rapid and accurate detection of the characteristic value of voltage sag is the premise of effective compensation of voltage sag. This paper analyzes detection algorithms: instantaneous voltage dq transformation, dq transformation based on voltage derivative, Delay 90° αβ-dq transformation and αβ-dq transformation based on voltage derivative, they are simulated by Matlab/Simulink simulation software,and the simulation results are analyzed, a suitable detection algorithm for DVR is obtained.
