Harmonic Analysis in Power System using ZSI and Comparison with Conventional Inverter Techniques

Abstract

Harmonics can appear due to non uniform condition or non-linearity in system. Harmonics out-turn distortion, losses and finally reduction in quality and efficiency. Distortion triggered by harmonic meters in term of % of THD (total harmonic distortion) which tie-up with distortion factor (unity for pure sine wave). Using MATLAB a circuit is sketch, for analyzing different harmonic effect in different fault condition, faults condition (with suitable parameter) imposed on system. By using ZS (Impedance source), VS (Voltage source) and CS (Current source) type inverters in design system contrast or similarity between results is analyzed.
