Power System Harmonic Analysis Using ETAP

Power quality is a fundamental requirement of modern electrical power systems. The rapid growth of DC devices and non-linear loads has increased harmonic distortion, creating challenges for the reliability, efficiency, and safety of power networks. This book examines the causes and effects of power system harmonics and presents practical methods for harmonic analysis and mitigation. Using ETAP software, it demonstrates how complex power systems can be modeled, analyzed, and evaluated through harmonic load flow studies. The book explains the mathematical foundations of harmonic analysis, the identification of harmonic sources, and the assessment of current and voltage distortion throughout a network. A representative load is used to illustrate harmonic current injection and its impact on system performance. Combining theory with practical simulation, this work provides engineers and students with a clear understanding of harmonic analysis using ETAP and offers valuable guidance for improving power quality in modern electrical power systems.
