Informationen zum Autor Angelo Baggini is currently a Professor of Electrical Engineering at the University of Bergamo and also works as a consultant with his own company, Engineering Consulting and Design. He received his PhD in Electrical Engineering from the University of Pavia in 1997 with a thesis on 'EMC aspects on dry type cast resin power transformers' and is active in the technical communications field, having written 2 dissemination books, over 100 press and scientific articles and over 50 papers for seminars and conferences. He teaches courses on 'Elements of Electrical Power Engineering' and also has experience carrying out feasibility studies, energy audits and energy loss evaluation of transformers. He is a member of the Italian Electrical Committee (CEI) and the European Committee for Electrical Standardization (CENELEC), carrying out work for several committee standards groups. Klappentext 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 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.The 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.
