Analyse des harmoniques dans un Réseau Electrique en utilisant de logiciel ETAP

Abstract

The main intention of any electrical utility company is to deliver power with better quality. By increasing the use of power electronic devices (Nonlinear load), the power quality has been affected. One of the most important causes for improper power quality is power system harmonics. This has become a major issue for power quality problem and harmonic analysis needed to investigate in modeling components to minimize or remove this harmonics current or voltage. In this project, power system harmonic analysis has been performed using ETAP software and described the whole process in details. First of all, a general load was modeled as a harmonic source to inject harmonic current through the power network. Then, to analyze the effect of harmonic current, Harmonic Load Flow analysis was performed and harmonic distortion identified. To eliminate this harmonic distortion, different kinds of techniques have been used, one of which is the passive filter.
