The realization of precise real time harmonic analysis in the electric power system

Wang Xiaoqiang,Chen Mingkai(Fuzhou University,Fuzhou350002,China)  
This paper introduce an adaptive sampling harmonic analysis method which adapt to realization of precise real time harmonic analysis.This method adjusts sampling interval to trail after the power system frequency at the same time of harmonic analy-sis,so that this method greatly reduces the spectrum leakage.This paper also introduce recursive hartely transform algorithm which is highly-efficient ,simple and convenient to realize.
