Abstract: The seriousness of harmonic in power system was introduced, and those common analysis methods of it plus their advantages and disadvantages were briefly reviewed. The principle for harmonic detecting and analyzing based on Fourier transformation was focused on. Then features and advantages of virtual instrument techmique plus its differences from traditional instrument analyzing techniques were stated briefly. Finally, software/hardware components of harmonic detecting and analyzing system based on virtual instrument technique for power system were suggested, operation results of this system were also analyzed.

Keywords: Harmonic; Virtual instrument; Fourier transformation
