This book provides the electrical design engineer with an insight into the properties and applications of electrical steels which are used in transformers and rotating machines. An acknowledged international expert in this field, Professor Beckley describes the principles controlling the action of electrical steels, including rotational loss and the influence of compressional stresses in transformers and rotating machines. The coverage of this book includes: manufacturing methods and applications, machine structuring and operation, cost versus quality issues, and physical properties including the magnetic response of composites, amorphous and microcrystalline materials.

In the future, the UK's energy supplies, for both heat and power, will come from much more diverse sources. In many cases, this will mean local energy projects serving a local community or even a single house. What technologies are available? Where and at what scale can they be used? How can they work effectively with our existing energy networks? This book explores these power and heat sources, explains the characteristics of each and examines how they can be used.

If there are two phrases we have come to know very well, they are 'environmental awareness' and 'credit crunch'. The world is looking for ways to decrease the emission of CO2 into the atmosphere, without incurring major costs in doing so. By increasing efficiencies up to about 90 per cent using well-established and mature technologies, cogeneration represents the best option for short-term reductions in CO2 emission levels. The ability to maximise revenue streams by taking advantage of price fluctuations in the cost of energy supply, and ensuring the ability to supply power regardless of what is happening on the grid, are powerful incentives to use cogeneration. The collapses of the grid networks in North America and Italy in 2003 were a stark reminder of what can happen if there is over-reliance on the grid network. Cogeneration makes sense economically, environmentally and operationally.

An introduction to the analysis of electric machines, power electronic circuits, electric drive performance, and power systems This book provides students with the basic physical concepts and analysis tools needed for subsequent coursework in electric power and drive systems with a focus on Tesla’s rotating magnetic field. Organized in a flexible format, it allows instructors to select material as needed to fit their school’s power program. The first chapter covers the fundamental concepts and analytical methods that are common to power and electric drive systems. The subsequent chapters offer introductory analyses specific to electric machines, power electronic circuits, drive system performance and simulation, and power systems. In addition, this book: Provides students with an analytical base on which to build in advanced follow-on courses Examines fundamental power conversions (dc-dc, ac-dc and dc-ac), harmonics, and distortion Describes the dynamic computer simulation of a brushless dc drive to illustrate its performance with both a sinusoidal inverter voltage approximation and more realistic stator six-step drive applied voltages Includes in-chapter short problems, numerous worked examples, and end-of-chapter problems to help readers review and more fully understand each topic

Energy Storage for Power Systems

The supply of energy from primary sources is not constant and rarely matches the pattern of demand from consumers, and electricity itself is difficult to store in significant quantities. Secondary storage of energy is therefore required both for more efficient use of existing generation capacity and to allow more substantial use of renewable energy sources that tend to provide energy only intermittently. Lack of effective storage has often been cited as a major hurdle to substantial introduction of renewable energy sources into the electricity supply network. The author presents here a comprehensive guide to the different types of storage available. He not only shows how use of the various types of storage can benefit the management of a power supply system but extends this to consider more substantial possibilities that arise from integrating a combination of different storage devices into a system. His book will therefore be important to those seeking to develop environmentally sound energy resources.
