Harmonics Measurement and Analysis of Grid-Connected PV System

MA Jie,ZHANG Jian-cheng(School of Electrical and Electronic Engineering,North China Electric Power University,Baoding 071003,Hebei Province,China)  
The parallel operation of the PV system in the power grid will bring a series of problems in the power grid,one of which is the harmonic pollution.In order to address this problem,it is necessary to measure harmonics before the PV system is integrated into the power grid.This paper presents a windowed interpolation FFT algorithm in detecting the parameters of harmonics and demonstrates the effectiveness of the algorithm.Furthermore,the algorithm is applied in detecting and analyzing the harmonic current of the PV parallel model in the paper.
