A High Speed Wind Turbine with Aeromechanical Pitch Regulation System

Mr. Yuri Favorsky is the chief engineer and the deputy director at the Institute of Renewable Energy of the National Academy of Sciences of Ukraine and the founder and owner of the private company Avante. His wind energy conversion system (WECS) is a high speed wind turbine equipped with aeromechanical pitch control system. The blades of the wind turbine are turned around their axles by stabilizers, which are attached to the trailing edges of the blades. The nacelle, or the wind wheel, is fastened to the tower with the yawing support and allows the wind turbine to orient itself downwind. The pitch regulation system ensures reliable and effective windmill operation at wind speed from 2.5 to 55m/s, even when the wind is gusty. The VEU-075 system uses a low-speed synchronous generator with permanent magnet (GPM) to eliminate the need for a multiplier and an electric magnetization system. The energy produced is stored in standard automotive or stationary storage battery. The tower of the wind turbine is designed with steel pipes for ease of construction and transportation. It has the advantages of low cut-in and rated wind speed and wide range of operating wind speed (from 3 to 7 m/s).
