Flashcards
Wind Turbine Power Equation
Wind Turbine Power Equation
The power generated by a wind turbine is calculated using $P = K ullet V^{3}$.
Power Dependency
Power Dependency
Power is directly proportional to the cube of wind speed, meaning small increases in speed yield larger power increases.
