Wind Turbine Data
Wind Power Generator Parameters
The mechanical power of the wind turbine can be calculated from equation (1) while the power coefficient is given in (2) and (3). The parameters for the different turbines are shown on pages 2, 3, and 4, the same power coefficient equation should be used for all the different projects. If you have already used another set of generator parameters and power coefficient this is OK but please reference where you have got them from.
