Download or read book Reactive Power Compensation written by Wolfgang Hofmann and published by John Wiley & Sons. This book was released on 2012-02-23 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: The comprehensive resource on reactive power compensation, presenting the design, application and operation of reactive power equipment and installations The area of reactive power compensation is gaining increasing importance worldwide. If suitably designed, it is capable of improving voltage quality significantly, meaning that losses in equipment and power systems are reduced, the permissible loading of equipment can be increased, and the over-all stability of system operation improved. Ultimately, energy use and CO2 emisson are reduced. This unique guide discusses the effects of reactive power on generation, transmission and distribution, and looks at the compensation of existing installations in detail. It outlines methods for determination of reactive power and answers the questions that arise when controlling it, for example, at parallel operation with generators. There is also a chapter devoted to installation, maintenance and disturbances. Key features include: A concise overview as well as deep specific knowledge on the segment power factor regulation and network quality Theory of reactive power compensation coupled with typical application examples such as car manufacturing, metal rolling and chemical works Chapter summaries with charts explaining how to put the theory into practice Coverage on the cost-saving aspects of this technology, including the efficient use of energy and the reduction of CO2 A practical guide for electrical engineers and technicians in utilities, this is also essential reading for maintenance engineers, designers, electrical contractors, manufacturing companies, and researchers, also those in industry and planning agencies. Insightful and clear, the book will also appeal to senior undergraduate and graduate electrical engineering students and professors.

This book was released on 2020-06-19 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Power systems have two components of apparent power: active and reactive power. Both components are necessary for functioning of electrical systems. The active power is the average power absorbed by the resistive load. The reactive power is the measure of energy exchange between the source and reactive power of load. Energy storage devices do not dissipate or supply power, but exchange power with the rest of system. Active power is the one that is converted to other forms of energy in the load yet reactive power is only responsible for magnetizing purposes. Power factor is a ratio depicting how much of the power supplied is real. The reactive current contribute in the value of the overall magnitude of current in transmission lines causing unnecessarily high line currents and low power factor. Since a low power factor means higher amount of apparent power need to be supplied by the utility company, thus the company must also use bigger generators, large transformers and thicker transmission/distribution lines. This requires a higher capital expenditure and operational cost which usually result in the cost being passed to the consumer.In this research, we seek to identify the effects of a low power factor on Swaziland Electricity Companys power supply system and recommend possible solutions to the problem. The results are useful in determining how to optimally deliver power to a load at a power factor that is reasonably close to unity, thus reducing the utilitys operational costs while increasing the quality of the service being supplied.

Available in PDF, EPUB and Kindle. Book excerpt: This book describes the fundamental aspects of the new generation of electrical distribution grids, taking as its starting point the opportunities that exist for restructuring existing infrastructure. It emphasizes the incorporation of renewable energy sources into the distribution grid and the need for a technological evolution towards the implementation of smartgrids. The book is organized into two parts: the first part analyzes the integration of distributed energy sources into the distribution grid and the impact of these sources on grid operation. After a general description of the general characteristics of distribution grids and renewable energy sources, it then analyzes the economics of electrical energy distribution networks and presents the impact of these sources on grid operation. The second part of the book then analyzes the various functions which allow for safe operation of the grid and realization of the path towards real world application of smartgrids.

Book excerpt: 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.
