基于小波变换模极大值的电能质量扰动检测与定位
DETECTION AND LOCATION OF POWER QUALITY DISTURBANCES USING WAVELET TRANSFORM MODULUS MAXIMA
摘要
Abstract
With the wide application of sensitive power electronic devices in industry, the power quality disturbance problems such as voltage sag and swell become more concerned. The detection and location of the start point and end point of the voltage sag and swell is a key problem for the power quality monitoring. The principle of singularity detection using wavelet transform modulus maxima is presented in this paper and a dyadic wavelet transform approach for the detection and location of the power quality disturbances such as voltage sag and swell in distribution systems is proposed. The validity of the proposed method is verified by the results of the simulation.关键词
