Quality electricity supply propels industrial growth and boosts economic development. Quality electricity supply goes beyond mere availability of electricity as it is commonly believe to be. This book examines the various elements of quality electricity supply. The book also discussed industrial performance as a whole and identified four (4) key performance indicators that industries measure. It then considered the impact that electricity has on industries and their performance citing cases of Africa, America, Europe, Middle East and Asia. It then identified six general areas that quality electricity supply could impact in any industry.
Frequency disturbances, transients, grounding, interference...the issues related to power quality are many, and solutions to power quality problems can be complex. However, by combining theory and practice to develop a qualitative analysis of power quality, the issues become relatively straightforward, and one can begin to find solutions to power quality problems confronted in the real world. Power Quality builds the foundation designers, engineers, and technicians need to survive in the current power system environment. It treats power system theory and power quality principles as interdependent entities, and balances these with a wealth of practical examples and data drawn from the author's 30 years of experience in the design, testing, and trouble-shooting of power systems. It compares different power quality measurement instruments and details ways to correctly interpret power quality data. It also presents alternative solutions to power quality problems and compares them for feasibility and economic viability. Power quality problems can have serious consequences, from loss of productivity to loss of life, but they can be easily prevented. You simply need a good understanding of electrical power quality and its impact on the performance of power systems. By changing the domain of power quality from one of theory to one of practice, this book imparts that understanding and will develop your ability to effectively measure, test, and resolve power quality problems.
Both deregulation in the electrical supply industry and the creation of new electricity markets present electric utility companies with the challenge of becoming more efficient without compromising quality of service. Providing new solutions for this newly deregulated paradigm, Power Quality: VAR Compensation in Power Systems presents comprehensive coverage of power quality, harmonics, and static var compensators in one single volume. The book explains how to ensure that power quality is not affected by the harmonics generated by power electronic equipment and explains how to reduce labor costs and increase reliability of supply by employing a single pole autoreclosing scheme. It also addresses how to analyze frequency response of current transformers and voltage transformers while measuring harmonics. Based on the authors’ extensive experience in the electric supply industry, Power Quality enables engineers to meet the demands of increased loads, strengthen their transmission systems, and ensure reliable electric supply.
This Edited Volume Power Quality - New Insights is a collection of reviewed and relevant research chapters, offering a comprehensive overview of recent developments in the field of engineering. The book comprises single chapters authored by various researchers and edited by an expert active in the power quality research area. All chapters are complete in themselves but united under a common research study topic. This publication aims to provide a thorough overview of the latest research efforts by international authors on power quality and open new possible research paths for further novel developments.
Due to the complexity of power systems combined with other factors such as increasing susceptibility of equipment, power quality (PQ) is apt to waver. With electricity in growing demand, low PQ is on the rise and becoming notoriously difficult to remedy. It is an issue that confronts professionals on a daily basis, but few have the required knowledge to diagnose and solve these problems. Handbook of Power Quality examines of the full panorama of PQ disturbances, with background theory and guidelines on measurement procedures and problem solving. It uses the perspectives of both power suppliers and electricity users, with contributions from experts in all aspects of PQ supplying a vital balance of scientific and practical information on the following: frequency variations; the characteristics of voltage, including dips, fluctuations and flicker; the continuity and reliability of electricity supply, its structure, appliances and equipment; the relationship of PQ with power systems, distributed generation, and the electricity market; the monitoring and cost of poor PQ; rational use of energy. An accompanying website hosts case studies for each chapter, demonstrating PQ practice; how problems are identified, analysed and resolved. The website also includes extensive appendices listing the current standards, mathematical formulas, and principles of electrical circuits that are critical for the optimization of solutions. This comprehensive handbook explains PQ methodology with a hands-on approach that makes it essential for all practising power systems engineers and researchers. It simultaneously acts as a reference for electrical engineers and technical managers who meet with power quality issues and would like to further their knowledge in this area.
Of the "big three" components of electrical infrastructure, distribution typically gets the least attention. In fact, a thorough, up-to-date treatment of the subject hasn’t been published in years, yet deregulation and technical changes have increased the need for better information. Filling this void, the Electric Power Distribution Handbook delivers comprehensive, cutting-edge coverage of the electrical aspects of power distribution systems. The first few chapters of this pragmatic guidebook focus on equipment-oriented information and applications such as choosing transformer connections, sizing and placing capacitors, and setting regulators. The middle portion discusses reliability and power quality, while the end tackles lightning protection, grounding, and safety. The Second Edition of this CHOICE Award winner features: 1 new chapter on overhead line performance and 14 fully revised chapters incorporating updates from several EPRI projects New sections on voltage optimization, arc flash, and contact voltage Full-color illustrations throughout, plus fresh bibliographic references, tables, graphs, methods, and statistics Updates on conductor burndown, fault location, reliability programs, tree contacts, automation, and grounding and personnel protection Access to an author-maintained support website, distributionhandbook.com, with problems sets, resources, and online apps An unparalleled source of tips and solutions for improving performance, the Electric Power Distribution Handbook, Second Edition provides power and utility engineers with the technical information and practical tools they need to understand the applied science of distribution.
Power distribution and quality remain the key challenges facing the electrical utilities industry. Technology alone cannot provide a solution to power quality problems, and there exists a variety of procedures and programs that can be put in place to ensure reliable, high quality electricity. With chapters carefully culled from the best-selling Electric Power Distribution Handbook, Distribution Reliability and Power Quality provides an economical, sharply focused reference for engineers and technicians working in this specialty area of power distribution. The book introduces the concept of reliability, outlining various methods of assessing and improving reliability along with the factors that affect it. It follows with a detailed look at voltage sags and momentary interruptions, various solutions to these issues, power quality monitoring, and other quality issues such as voltage unbalance and harmonics. Because faults are the cause of many interruptions and other power quality problems, the author devotes a detailed chapter to various aspects of faults. Focused on enhancing the delivery of high-quality power, this volume includes a new chapter on reliability and power quality improvement programs that provide a roadmap to better performance and ultimately to higher efficiency. Presenting a host of practical solutions for reliability and power quality specialists, Distribution Reliability and Power Quality gathers critical tools, techniques, and knowledge into a single source that is ideally suited for immediate implementation.
