基于复数域偏最小二乘法与等值法的多谐波源责任划分
Responsibility Distinction for Multiple Harmonic Sources Based on Partial Least Square in Complex Field and Equivalent Method
摘要
Abstract
The estimation of the harmonic impedance based on linear regression is one of the commonly used estimation methods.In order to ensure the correlation between real part and imaginary part of the harmonic impedance estimation,the strict mathematical derivation and simplified solution procedure of the single dependent variable complex domain partial least square method is presented.In view of the responsibility distinction for multiple harmonic sources at the public connection point,based on the actual recorded data,by analyzing the relationship between the current fluctuation of each feeder line,the index factor has been obtained,which is used to get the dominant fluctuation filtering to screen the data between voltage and current with good linearity.Then the harmonic impedance of the equivalent system is estimated by the partial least squares regression in the complex field.Finally,the quantitative responsibility distinction of each harmonic source is realized by virtue of the equivalent method proposed,its feasibility and effectiveness are verified by simulation and experimental results.关键词
