Power Quality Improvement in Distribution Systems Using Shunt Hybrid Active Power Filter

This book describes the introduction to power quality, causes of current harmonics, and their effect on different power system equipment. It also discusses harmonic mitigation methods starting from passive filters to active filters and hybrid filters. The SHAF topology, its operating principle, its control of it, and how this system can mitigate current harmonics and improves power factor. It also presents the mathematical modeling of shunt active filter, designing of the power circuit, interfacing inductor, DC bus capacitor, tuned passive filter, d-q-0 theory-based reference compensation current generation, hysteresis current controller for switching signal generation, and fuzzy logic based DC bus voltage controller It presents the development of MATLAB/SIMULINK simulation model of shunt hybrid active filter and its controllers for reducing harmonic distortion in the source current.

This book explores the concept of power quality and its challenges, particularly the impact of harmonic distortions on electrical systems. It defines power quality and reviews common power disturbances like voltage sags, transients, and harmonics. With the rise of non-linear loads in industrial, commercial, and residential settings, harmonics have become a significant concern. The book details the effects of harmonics on motors, transformers, and safety devices, offering practical insights into mitigating these issues. A valuable resource for professionals seeking to enhance power system performance, this book aids in addressing power quality problems effectively.
