Based on the fractal technology of harmonic detection method in power system
The harmonic pollution is one of the serious problems which impact on power system security and stability.With the development of power electronic technology,harmonic problems become increasingly prominent.Harmonic detection is an important content in the harmonic problems,is the base to solve the problem of harmonic.The harmonic of power system have characteristics of random and nonstationary,not easy to detect,in recent years,a variety of detection methods emerge in an endless stream,this paper introduces a technique of detecting harmonics in power system by using fractal method,this method by calculating the dynamic waveform grid fractal dimension,setting threshold value,and determines the waveform distortion occurring time.After the theoretical analysis and practical measurement,this method can be effectively used on harmonic detection and can meet the requirements in speed and accuracy.
