Assume that the annual energy requirement of an industry is 20,000 kWh. What should be the size of wind turbine that is required to be installed to meet energy requirement? The following assumptions are take into account for estimation: Annual energy requirement - 20000 kWh Propeller type wind machine is used Coefficient of performance - 0.40 Wind speed at 15 metre height is 5 metres/sec (if the turbine hub is placed at the height other than 15 metres, the wind speed should be estimated as shown in 'vertical wind speed variation section') • • • Density of air - 1 kg/m² • Capacity factor -0.30 (i.e. 30 % of the time, wind machine is producing energy at rated power) • Number of hours in a year - 8760 hours Correctly determining the energy density Correctly determining the area of the rotor Correctly determining the radius of the rotor blade Correctly determining the power rating of the turbine Assume that the annual energy requirement of an industry is 20,000 kWh.
