Detection of Power System Harmonics Using NBPSO Based Optimally Placed Harmonic Measurement Analyser Units

Abstract

Nonlinear loads are the source of harmonic injections in power system. These are complains in distortion of sinusoidal voltage and current waveforms. This paper objective is to detect harmonic sources and calculations of their injection levels to enhance power quality. For the proposed methodology the Niche Binary Particle Swarm optimization (NBPSO) technique is used to place optimally Harmonic Measurement Analyzer (HMA) units in power system to make entire system observable and worthwhile.
