Neither, the annual energy output, nor the power curve of a wind turbine cannot give an exact estimate of the turbine performance in a site. A new performance index is introduced in this paper for the wind turbines in potential sites. That index can be used for evaluation of a wind turbine in a site, where the wind speed information at that site should be available. The wind turbine operation as well as the controller performance can be evaluated using this new performance index. Simulation studies showed the effectiveness of the proposed method based on the new performance index<\div>

In this paper simulation of the Rutland wind turbine is presented. Different mechanical and electrical parts and elements in the system are precisely modelled. The power coefficient curve modelling is selected as the appropriate model, among the blade element theory, empirical modelling and the power curve modelling. The power coefficient curve is found through a series of wind tunnel tests.As the wind speed estimation at the turbine location is problematic, three anemometers have been utilised to measure the wind speed around the wind turbine. A new model is developed, in this paper, for better estimation of the wind speed at the wind turbine location from the three measurements.For validating the simulation, the power spectrum comparison of the signals in simulation and the real measurements, is incorporated. The sources of errors between the simulation and the measurements are explained. It is presented in this paper that how the model can be utilised to investigate control of the wind turbines<\div>
