A new method is proposed for determining a Nacelle Transfer Function (NTF), in which an individual NTF is provided for each wind turbine compensating for both structural effects, those that arise from the shape and configuration of the wind turbine, and environmental effects, those that are a result of the terrain or geographical location. Based on the assumption that the turbine is running correctly and SCADA data is taken over a certain period, and based on a siting model to give data on Turbulence Intensity (TI), ?pflow, shear and other atmospheric parameters (as a function of wind speed and wind direction as necessary) the NTF can be determined from a site specific power curve made generated using a computer model. The NTF is the function that gives the required site power curve over the period that data is available. Unlike, previous techniques, there is no requirement to use a met mast. |
