Abstract

A multifunctional virtual power quality monitoring system is designed and implemented in LabVIEW environment. S-transform is introduced and applied to perform time-frequency analysis on power quality disturbances. The root mean square (RMS) value, the waveforms of three-phase voltage and current, the harmonic components, the total harmonic distortion (THD) and S-transform analysis waveforms of the three-phase voltage and current signals can be calculated and displayed in the system. Furthermore, the remote transfer of measured results is implemented using the AppletVIEW Toolkit in LabVIEW adopting a B/S framework. Measurement results show the feasibility and validity of the system.
