An Interactive Framework for Power System Harmonics Measurement Using Graphical Programming and the Internet

摘要

Traditional methods to measure power system harmonics employ the power harmonic analyser or the software package such as Matlab. They, however, have limitations in capability of graphical programming environment and extension to the Internet connection for remote monitoring and control. This paper presents an alternative approach using a virtual instrument (VI) that can carry out power system harmonics measurement based on Fast Fourier Transform (FFT). The experimental results testify to its good performance and remote monitoring capability.
