Turbine Power Output vs Wind Speed

Vedi formula →

Formula

## Wind Turbine Power Wind power depends on the cube of wind speed and the swept area of the rotor. ### Formula **P_available = 0.5 rho A V^3** (total wind power) **P_output = 0.5 rho A V^3 Cp** (extracted power) where rho is air density, A is the swept area (pi D^2/4), V is wind speed, and Cp is the power coefficient. The Betz limit states maximum Cp = 16/27 = 59.3%. Practical turbines achieve 35-45%.

Esempio Risolto

An 80 m rotor diameter turbine in 8 m/s wind, Cp = 0.40.

  1. 01Swept area = pi x 40^2 = 5,027 m^2
  2. 02Available power = 0.5 x 1.225 x 5027 x 8^3 = 0.5 x 1.225 x 5027 x 512
  3. 03Available = 1,576,461 W = 1,576 kW
  4. 04Output = 1,576 x 0.40 = 630.6 kW
