Power Harmonic Analysis System Based on Virtual Instrument

Abstract:

This paper presents a power harmonic analysis system based on virtual instrument. LabVIEW data acquisition module was used to acquire waveform data in this system. Combined with FFT (Fast Fourier Transform) and phase difference correction method, amplitude, phase and frequency information of voltage and current’s every harmonic are obtained successfully. LabVIEW rich controls are employed to complete GUI (Graphical User Interface) design under windows and constructs network through TCP protocol. The realization and simulation of the harmonic detection algorithm are discussed in detail.
