The purpose of this book is to describe the theory of Digital Power Electronics and its applications. The authors apply digital control theory to power electronics in a manner thoroughly different from the traditional, analog control scheme. In order to apply digital control theory to power electronics, the authors define a number of new parameters, including the energy factor, pumping energy, stored energy, time constant, and damping time constant. These parameters differ from traditional parameters such as the power factor, power transfer efficiency, ripple factor, and total harmonic distortion. These new parameters result in the definition of new mathematical modeling:
- A zero-order-hold (ZOH) is used to simulate all AC/DC rectifiers.
- A first-order-hold (FOH) is used to simulate all DC/AC inverters.
- A second-order-hold (SOH) is used to simulate all DC/DC converters.
- A first-order-hold (FOH) is used to simulate all AC/AC (AC/DC/AC) converters.

The liberalization of U.S. and European electric power markets presents a critical challenge for renewable sources of energy. Edinger and Kaul survey the technological state-of-the-art and economic aspects of renewable electricity generation, and outline the role of other renewable sources, such as solar, wind, and micro-hydroelectric technologies. Offering an empirical and theoretical assessment of these technologies and their assets and liabilities, the book shows how it is possible to restructure our electric power systems and reorient them toward sustainable and environmentally friendly alternatives.

International climate conferences such as those in Rio de Janeiro and Kyoto have proclaimed the need for environmentally hospitable technologies. A new electricity system, based on renewable resources and small-scale power technologies, is needed badly; their economics and other efficiencies over conventional central power generation with fossil fuels is clear. Edinger and Kaul assess the rewards and risks associated with renewable technologies and outline a feasible path toward a more environmentally friendly, and reasonable, use of limited natural resources and the global ecosystem. One promising approach for industrialized countries is the decentralization of our current public grid systems. This offers an opportunity for developing countries to leapfrog the stage of fossil fuel, held responsible now for environmental pollution, resource depletion and possibly global climate change. The authors present theoretical analyses and empirical evidence to buttress their contentions, mainly, that electric power systems founded on renewable resources are vital prerequisites if we are to achieve the United Nations' target of globally sustained development.

On August 6 and August 9, 1945, the world became aware of the destructiveness of nuclear energy when the U.S. Army Air Corps dropped atomic bombs on Hiroshima and Nagasaki. Even before the bombs were detonated, though, President Harry Truman had directed his thoughts toward non-military uses of the atom, recognizing that the atomic bomb had given man a new understanding of the forces of nature. This book examines the history and development of nuclear power from the perspective of the U.S. Army's nuclear power program, telling its story from the creation of the Office of Research and Development through the program's days of growth,and on to its eventual decline. This history examines the development of the United States Army's nuclear power program from its inception, through the development and operation of six small nuclear power plants throughout the Western Hemisphere, to its evolution into a military support agency. The Manhattan Project District Engineer, General Kenneth Nichols, who generated the idea for the program, worked for the development of atomic energy for peaceful purposes. From the initial plans to develop nuclear power plants at remote bases, the book traces the path the Army took in getting its proposals approved by the Atomic Energy Commission, formally organizing the nuclear program, and building a prototype of a nuclear power plant. Separate chapters are devoted to Fort Greely, the nuclear program at the height of its success and accomplishment, and its subsequent decline and transitional period. With its list of suggestions for further reading and a comprehensive index, this volume will be a valuable resource for courses in military history, energy issues, and the development of atomic power. It will also represent an important addition to college, university, and public libraries.

Power System Restoration meets the complex restoration challenges that arise by the dynamic capabilities of new technology in areas such as large-scale system analysis, communication and control, data management, artificial intelligence, and allied disciplines. It provides an up-to-date description of the restoration methodologies and implementation strategies practiced internationally. The book opens with a general overview of the restoration process and then covers:
* Techniques used in restoration planning and training
* Knowledge-based systems as operational aids in restoration
* Issues associated with hydro and thermal power plants
* High and extra-high voltage transmission systems
* Restoration of distribution systems
Power System Restoration is essential reading for all power system planners and operating engineers in the power industry. It is also a valuable reference for researchers, practicing power engineers, and engineering students.

The history of the grid, the world's largest interconnected power machine that is North America's electricity infrastructure. The North American power grid has been called the world's largest machine. The grid connects nearly every living soul on the continent; Americans rely utterly on the miracle of electrification. In this book, Julie Cohn tells the history of the grid, from early linkages in the 1890s through the grid's maturity as a networked infrastructure in the 1980s. She focuses on the strategies and technologies used to control power on the grid-in fact made up of four major networks of interconnected power systems-paying particular attention to the work of engineers and system operators who handled the everyday operations. To do so, she consulted sources that range from the pages of historical trade journals to corporate archives to the papers of her father, Nathan Cohn, who worked in the industry from 1927 to 1989-roughly the period of key power control innovations across North America. Cohn investigates major challenges and major breakthroughs but also the hidden aspects of our electricity infrastructure, both technical and human. She describes the origins of the grid and the growth of interconnection; emerging control issues, including difficulties in matching generation and demand on linked systems; collaboration and competition against the backdrop of economic depression and government infrastructure investment; the effects of World War II on electrification; postwar plans for a coast-to-coast grid; the northeast blackout of 1965 and the East-West closure of 1967; and renewed efforts at achieving stability and reliability after those two events.
