居民配电网负荷谐波电流发射水平评估方法
The Harmonic Current Emission Level of the Residential Loads in the Distribution Network
摘要
Abstract
This paper presents a method to assess the harmonic current contributions at the PCC,and introduce two indices of the harmonic current contribution and probability distribution curves.The harmonic impedance is evaluated with the symbolic discriminated method and the canonical correlation analysis method respectively,and then the residential harmonic emission level is qualified.The simulation and practical case study results prove that the canonical correlation analysis method has a better accuracy to assess the harmonic impedance than the symbolic discriminated method does.Moreover,the canonical correlation analysis method is applicable in the scenario that the harmonic fluctuation of the system side is bigger than that of the customer side.The harmonic current probability distribution curves show multi-peaks characteristics,which can reflect the combination of electrical appliances.The study results are useful to identify the residential harmonic sources and to determine the control measures and supervision policy.关键词
