Handbook Of Power Quality

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.

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.

Bridging the gap between power quality and signal processing This innovative new text brings together two leading experts, one from signal processing and the other from power quality. Combining their fields of expertise, they set forth and investigate various types of power quality disturbances, how measurements of these disturbances are processed and interpreted, and, finally, the use and interpretation of power quality standards documents. As a practical aid to readers, the authors make a clear distinction between two types of power quality disturbances: * Variations: disturbances that are continuously present * Events: disturbances that occur occasionally A complete analysis and full set of tools are provided for each type of disturbance: * Detailed examination of the origin of the disturbance * Signal processing measurement techniques, including advanced techniques and those techniques set forth in standards documents * Interpretation and analysis of measurement data * Methods for further processing the features extracted from the signal processing into site and system indices The depth of coverage is outstanding: the authors present and analyze material that is not covered in the standards nor found in the scientific literature. This text is intended for two groups of readers: students and researchers in power engineering who need to use signal processing techniques for power system applications, and students and researchers in signal processing who need to perform power system disturbance analyses and diagnostics. It is also highly recommended for any engineer or utility professional involved in power quality monitoring.

This handbook offers a comprehensive source for electrical power professionals.
