Bianchi, F. D. et al. Springer-Verlag 2007. * Modern wind turbines generally operate at variable speed in order to maximise the conversion efficiency below rated power and to reduce loading on the drive-train. In addition, pitch control of the blades is usually employed to limit the energy captured during operation above rated wind speed. The higher complexity of variable-speed variable-pitch turbines is offset by the benefits of control flexibility, namely, higher conversion efficiency, better power quality, longer useful life; because of the immediate impact of control on the cost of wind energy, reliable high-performance controllers are essential in making wind technology competitive. * Soares, C. Butterworth-Heinemann 2007.6 *It will explain how a microturbine the size of a refrigerator can power an entire school, hospital or small factory, which is particularly useful for onsite, remote installations. The book will also show how microturbines can be paired with one or more fuel cells to form a hybrid energy source, or can be teamed with any source of distributed power, such as a mall hydro-turbine or a wind turbine. Moreover, the reader will learn how microturbines can run on a variety of fuels that are far cruder than those required by most standard gas turbines; they can be made to run, for instance, using gas from a landfill or biomass source. The reader will find detailed information on costs, specifications, and maintenance and repair guidelines. Ample references and resources will provide the reader with tools for finding manufacturers and product specifications for their own particular needs. * Dunn-Rankin, D. ed. Academic Press 2007.8 * Combustion under sufficiently fuel-lean conditions can have the desirable attributes of high efficiency and low emissions, this being particularly important in light of recent and rapid increases in the cost of fossil fuels and concerns over the links between combustion and global climate change. Lean Combustion is an eminently authoritative, reference work on the latest advances in lean combustion technology and systems. It will offer engineers working on combustion equipment and systems both the fundamentals and the latest developments in more efficient fuel usage and in much-sought-after reductions of undesirable emissions, while still achieving desired power output and performance. This volume brings together research and design of lean combustion systems across the technology spectrum in order to explore the state-of-the-art in lean combustion and its role in meeting current and future demands on combustion systems. * Mertens, S. * The author's analysis leads him to conclude that wind energy conversion in the built environment, making use of the concentrator effect of buildings, is a promising renewable energy source. * Akhmatov, Y. * This book focusses on the development of dynamic models of different wind turbine concepts and the understanding of the interaction between wind turbines and transmission power grids. As about 85% of the wind turbine market comprises wind turbines equipped with either fixed-speed or variable-speed converter-controlled induction generators, this book concentrates on induction generator-based wind turbines. As the power rating of wind turbines rapidly increases and power electronics converters become commonplace in generator control, this book presents details about power electronics converters' modelling with regard to short term voltage stability, control, protection and fault ride-through capability. * Peinke, J. et al. ed. Springer-Verlag 2007. * This book comprises reports on basic research, as well as research related to the practical exploitation and application of wind energy. "Wind Energy" comprehensively describes the atmospheric turbulent wind condition on different time scales, and the interaction of wind turbines with both wind and water flows, which are significant factors to consider for the design, operation and maintenance of wind turbines in offshore conditions. * |
