Aerodynamic Factors Affecting Wind Turbine Power Generation

Khalfallah, M. and Koliub, M. 2007 shown that Wind speed has a significant effect on wind turbine performance. The power available in the wind is directly proportional to the cube of wind speed and swept area of blades. As swept area of blades increases, the available power also increases. The output of a wind turbine is also directly

According to the wind power equation, the power generation performance of wind turbines is directly proportional to air density. The international electrotechnical commission (IEC) 61400-12-1 standard provides a method to convert power curves at different air densities to a reference air density for comparison, based on the wind power equation.

Study on the Pitch Angle Effect on the Power Coefficient and

For vertical axis wind turbines (VAWTs), the increase of the incoming wind speed higher than the rated value will make the tip speed ratio (TSR) lower and lower, resulting in the blade fatigue load becoming more and more severe and the power coefficient weakening gradually. This paper explores whether varying the pitch with the TSR decrease is necessary
