Abstract

Application of nonlinear - load especially power electronic devices in power system causes the increase of harmonics content. It causes greatly harmful to the stable operation of power grids, and power systems equipment. Traditional harmonics monitoring system is mainly based on hardware, Because of its simple function; it has a lot of disadvantages. This paper presents a design scheme of harmonics measurement and analysis system based on LabVIEW and FFT (fast Fourier transformation). The method of Detection, the composition of hardware and the harmonic measurement and analysis module block diagram are introduced.
