WebbVariable pitch control for vertical-axis wind turbines S Horb 1, R Fuchs , A Immas1, F Silvert and P Deglaire2 Abstract NENUPHAR aims at developing the next generation of large-scale floating offshore vertical-axis wind turbine. To challenge the horizontal-axis wind turbine, the variable blade pitch control appears to be a promising solution. Webb21 sep. 2016 · It is a rapid aerodynamic change that may bring about or delay stall behavior. Due to tower shadow, yaw or tilt, wind shear, and/or turbulent wind condition, the boundary begins to separate at the trailing edge and gradually moves upstream with increasing angles of attack, that is, dynamic stall.
WebbActive Stall-regulated Wind Turbines by Use of Multi-point Optimization”. It describes the full scale testing of a 21 m wind turbine blade specially designed for active stall regulation. Design objectives were increased ratio of produced energy to turbine loads and more stable power control characteristics.
