Harmonic Analysis for Power Loss Minimization in Radial Distribution System

A power quality problem such as high current harmonics, low power factor and an excessive neutral current result due to non-linear power electronic loads has a significant impact on industrial and commercial power distribution systems. In this regard, extensive surveys have reported quantifying the problems associated with electric power networks having nonlinear loads. The harmonics elimination is one category, where a composite signal carries the fundamental signal from the supply mains to the load. In this paper, a deep analysis of Harmonic has done to minimize the power loss in Radial Distribution System. In this work, the requirement of preserving the fundamental component from the supply signal with harmonics is best achieved in a non-invasive model. i.e. just observing the data, with the least complexity and mathematical transformations on it. The Hamming distance measure is repeated using the profile matrix and backtracking for every possible distinct composite wave of length l for identifying the string with maintaining the total Hamming distance in minimum range. The THD (Total Harmonic Distortion) is used as a metric to evaluate the effectiveness of the system. The model is simulated and the feasibility of the proposed model is justified by eliminating the unwanted signal in the form of harmonics.
