Power Quality

Maintaining a stable level of power quality in the distribution network is a growing challenge due to increased use of power electronics converters in domestic, commercial and industrial sectors. Power quality deterioration is manifested in increased losses; poor utilization of distribution systems; mal-operation of sensitive equipment and disturbances to nearby consumers, protective devices, and communication systems. However, as the energy-saving benefits will result in increased AC power processed through power electronics converters, there is a compelling need for improved understanding of mitigation techniques for power quality problems. This timely book comprehensively identifies, classifies, analyses and quantifies all associated power quality problems, including the direct integration of renewable energy sources in the distribution system, and systematically delivers mitigation techniques to overcome these problems. Key features: Emphasis on in-depth learning of the latest topics in power quality extensively illustrated with waveforms and phasor diagrams. Essential theory supported by solved numerical examples, review questions, and unsolved numerical problems to reinforce understanding. Companion website contains solutions to unsolved numerical problems, providing hands-on experience.
Senior undergraduate and graduate electrical engineering students and instructors will find this an invaluable resource for education in the field of power quality. It will also support continuing professional development for practicing engineers in distribution and transmission system operators. Professor Bhim Singh has worked at the IIT Delhi Department of Electrical Engineering since 1997.

Power Quality

Preface

Due to the increased use of power electronic converters in domestic, commercial, and industrial sectors, the quality of power in distribution networks is deteriorating at an alarming rate. This is causing a number of problems such as increased losses, poor utilization of distribution systems, mal-operation of sensitive equipment, and disturbance to nearby consumers, protective devices, and communication systems. These problems are also aggravated by the direct injection of non-steady power from renewable energy sources in the distribution system. It is expected that in the next few years, more than 80% of AC power is to be processed through power converters owing to their benefits of energy conservation, flexibility, network interconnection, and weight and volume reduction in a number of equipment such as lighting, HVAC, computers, fans, and so on. In view of these facts, it is considered timely to write this book to identify, classify, analyze, simulate, and quantify the associated power quality problems and thereby provide mitigation techniques to these power quality problems that will help practicing engineers and scientist to design better energy supply systems and mitigate existing ones.
Motivation

This book is aimed at both undergraduate and postgraduate students in the field of energy conversion and power quality in more than 10,000 institutions around the word. The book aims to achieve the following:


Easy explanation of the subject matter through illustrations, waveforms, and phasor diagrams using minimum texts, which is one of the most efficient methods of understanding complex phenomenon.
Simple learning of the subject through numerical examples and problems, which is one of the most favorite techniques of learning by engineering graduates.
To gain an in-depth knowledge of the subject through computer simulation-based problems, which is the most favored skill of today's young engineers.
To get the confidence to find the solutions of latest practical problems, which are encountered in the field of power quality.
To develop enthusiasm for logical thinking in students and instructors.
To gain an in-depth understanding of latest topics on power quality in minimum time and with less efforts. Focus and Target

This book is planned in a unique and different manner compared with existing books on the subject. It consists of rare material for easy learning of the subject matter and a large number of simple derivations are included in a simplified mathematical form for solving most of the power quality problems in analytical form and designing their mitigation devices. Aside from this, the book provides essential theory supported by a reasonable number of solved numerical examples with illustrations, waveforms and phasor diagrams, small review questions, unsolved numerical problems, computer simulation-based problems, and references.

In addition to undergraduate and postgraduate students in the field of power quality, this book will also prove useful for researchers, instructors, and practicing engineers in the field.

This book facilitates simplified mathematical formulations in closed form solution through calculation, computation, and modeling of power quality problems and designing their mitigation devices.
Structure

This book consists of 11 chapters. Chapter 1 gives an introduction on power quality (PQ), causes and effects of PQ problems, requirement of PQ improvements, and mitigation aspects of PQ problems. Chapter 2 deals with PQ definitions, terminologies, standards, benchmarks, monitoring requirements, financial loss, and analytical quantification through numerical problems.

In Chapters 3 - 6 , passive shunt and series compensation using lossless passive LC components, active shunt compensation using DSTATCOM (distribution
