A model for turbine array wake interference loss, based on part of the Lissaman model formulation, was developed for use with the results of the NOABL three-dimensional, mass consistent wind flow over complex terrain numerical model. The new model included the ability to utilize the complex three-dimensional wind field and terrain elevation for calculating the turbine wake interference losses in a nonuniform wind field; and included the ability to accept mixed, arbitrary turbine specifications. The new model was tested on a 718 turbine wind farm operated by Fayette Manufacturing Corporation in the Altamont Pass area of California. An estimate of the average summer season, undisturbed three-dimensional wind flow over the complex terrain of the wind farm was first obtained from the NOABL model using digitized terrain elevation data, and wind speed and direction data from 1983 for fifteen anemometer stations. The new turbine array wake interference loss model developed was used to calculate the average input speed to each of the 718 turbines in the wind farm array using the calculated undisturbed, three-dimensional wind flow field and the terrain elevation data.
