A wind turbine with a rotor diameter of 50 m is rated at Y kW at a hub height wind speed of m/s. It has a cut-in wind speed of m/s and a cut-out speed of m/s. Assume that this machine is located at a site where the mean wind speed is m/s and that a Weibull wind speed distribution can be used with a shape factor of 2.2. Calculate the following: 1. The number of hours per year that the wind is below the cut-in speed. 2. The number of hours per year that the machine will be shut down due to wind speeds above the cut-out velocity. 3. The energy production (kWh/yr) when the wind turbine is running at rated power.
