Course - DNV GL Energy Academy: Wind Turbine Technology

DNV GL Energy Academy: Wind Turbine Technology will take place on October 28 - 29, 2015 in Bristol, England. This two day course explains the basics of wind energy conversion and the evolution of today's giant wind turbines. It also reviews many key decisions about the design concepts of the turbine technology that is powering the fastest growing sector of the world’s electricity industries. This includes explanations behind the number of blades and locating turbines  upwind or downwind.

Rotor design, direct drive and the increasing diversity of drive train options are examined. Permanent magnet generators and general electrical design issues are addressed. The evolution of larger wind turbines and the challenges of further upscaling especially in the context of the expanding offshore market are also discussed. The design process, the importance of accurate design loads prediction and effective control of the wind turbine are highlighted. How design options may affect cost of energy is illustrated and future trends are reviewed.

The course offers a significant depth of understanding of the technology background but does not assume any prior knowledge of wind energy.

Who should attend?

Industry professionals wishing to broaden their knowledge; individuals or companies involved in wind farm or turbine development; and professionals of any discipline entering the industry and seeking specific skills, such as: Project Managers, Developers, Civil and Structural Designers, and Turbine Designers.
