| Abstract: | The harmonic measurement plays an important role in power system. In this paper, some main harmonics measurement methods are generally described, and a harmonic measurement method based on interpolating win-dowed FFT is discussed. According to the interpolating windowed FFT method, a multifunctional virtual instrument system for harmonic measurement of voltage and current signals is designed and implemented with LabVIEW environment. Compared with traditional harmonic measurement system, this system is flexi... |
