WebbIn a small-scale fixed-pitch variable-speed wind generation system, the power production has to adapt to various wind conditions by varying its rotation speed to achieve the maximum power extraction. However, this maximum power extraction behavior may result to over-rated operation of the system in high wind speed regions, where wind speed to … WebbHence, it can be shown that tubercles effectively control dynamic stall, reduce noise emissions, and increase the power output of VAWTs. AB - In recent days, enhancement of Vertical Axis Wind Turbines (VAWTs) by mitigating flow deteriorating effects like dynamic stalling, unsteady wake is given great importance.
