基于波形匹配的谐波责任划分方法
Waveform Matching Based Method for Harmonic Contribution Determination
摘要
Abstract
In order to quantify the harmonic contributions on the point of common coupling (PCC),a new method based on waveform matching is proposed.Firstly,a model of linear regression equation between harmonic voltage amplitude and harmonic current amplitude is established,which avoids the direct measurement of harmonic phase.In consideration of the error to the equation brought by the fluctuation of the background harmonic,the dynamic time warping (DTW) distance is used to analyze the harmonic data to select the sub sequences of high similarity.The utility equivalent harmonic impedance is estimated by the least square method,and then the customer harmonic contributions are calculated.The results of simulation and field measurement analysis show that the method has high accuracy and can restrain the influence of the fluctuating harmonic in the background.关键词
