Klappentext The authoritative reference on wind energy, now fully revised and updated to include offshore wind powerA decade on from its first release, the Wind Energy Handbook, Second Edition, reflects the advances in technology underpinning the continued expansion of the global wind power sector. Harnessing their collective industrial and academic expertise, the authors provide a comprehensive introduction to wind turbine design and wind farm planning for onshore and offshore wind-powered electricity generation.An all-important new chapter on offshore wind power covers:* resource assessment and array losses, optimal machine size and offshore turbine reliability* wave loading on support structure, including wind and wave load combinations and descriptions of applicable wave theories* the different types of support structure deployed to date, with emphasis on monopoles, including fatigue analysis in the frequency domain* the assessment of environmental impacts and the design of the power collection and transmission cable networkOther new coverage features:* turbulence models updated to reflect the latest design standards, including an introduction to the Mann turbulence model* extended treatment of horizontal axis wind turbines aerodynamics, now including a survey of wind turbine aerofoils, dynamic stall and computational fluid dynamics* developments in turbine design codes, comparison of options for variable speed opertion, and in-depth treatment of individual blade pitch control* techniques for extrapolating extreme loads from simulation results* an introduction to the NREL cost model* grid code requirements and the principles governing the connection of large wind farms to transmission networks* four pages of full-colour pictures that illustrate blade manufacture, turbine construction and offshore support structure installationFirmly established as an essential reference, Wind Energy Handbook, Second Edition will prove a real asset to engineers, turbine designers and wind energy consultants both in industry and research. Advanced engineering students and new entrants to the wind energy sector will also find it an invaluable resource.

Relazione

"I highly recommend the classic and definitive reference book Wind Energy Handbook, Second Edition by Tony Burton, Nick Jenkins, David Sharpe, and Ervin Bossanyi, to any engineering students in undergraduate or graduate studies, teaching academics, practicing engineers, business leaders in technology or electrical utilities, and government policy makers seeking a complete and authoritative overview of design, manufacturing, and installation of horizontal axis wind turbines. This book offers a complete survey of the field, and contains an important section on wind farms as well. Overall, this is a very important and essential addition to any study or practice in the field." (Blog Business World, 19 February 2012)"If libraries wish to acquire just one book on wind energy, this title is a very good candidate. Summing Up: Highly recommended. Upper-division undergraduates, graduate students, two-year technical program students, researchers/faulty, technicians/professionals, and informed general readers." (Choice, 1 December 2011)
