Abstract

This paper presents the design and implementation of a computer-based instrument to virtually monitor the quality of voltage, current and power in electric power systems. The proposed instrument is capable of performing online measurement functions, including data acquisition, display, and analysis, as well as data archiving. The analysis of concurrent voltage and current waveforms is performed using the wavelet packet transform (WPT) technique to provide the value of power quality (PQ) indices. In particular, the instrument also enables the display of both the temporal and spectral relationship of the original waveforms. Results of actual data are reported to validate the performance of the developed instrument.
