Expert System Design for Determining the Harmonic Resonance and the Capacitor Safety Level

Abstract

This paper presents a computer based expert system aiming the determination of harmonic resonance and the capacitor safety level. Developed applications for the determination of harmonic resonance are basically depending on the selection of a right harmonic impedance measurement method and the changes observed in the equivalent system impedance due to the occurrence of harmonic resonance. However, developed applications for the determination of capacitor safety level are depending on the international standards which introduce the related indices and limits for the capacitors and the fuzzy logic method. All developed applications were programmed using LabVIEWTM and the data required, is obtained continuously from real-time measurements.
