Найти книгу: "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.

Other enhancements and options that have been added and that you can find in this book are related to subjects such as the following: Availability is increased, and there are now further options for distributing the system, along with new powerful platforms. ? There is a new change and transport system, including all the facilities of the Transport Management System (TMS). ? In the ABAP workbench, there are a host of new utilities, a stepforward object?oriented ABAP, the replacement of matchcodes with search helps, and more. ? Windows NT is now a very popular platform with thousands of customers. For this reason, this new edition is operating system independent, dealing with both UNIX and Windows NT where appropriate. ? ? The authorization system and administrator duties have been facilitated with the profile generator. ? Since release 4.0 there is a new object?based monitoring architecture and alert monitors. ? The well?known OSS has now become SAPnet, with two variants: R/3 front end and Web front end. In this edition you will find lots of new things to discover and enjoy. I hope you enjoy this book and enjoySAP.
