Practical applications of a mathematical wake interaction model

Abstract

A semi-empirical wake-interaction model is described. This model is based on experimental results obtained using both wind tunnel models and full-scale wind turbines. Input data for the wake interaction model are wind direction and ambient turbulence, wind turbine characteristics and the position of the individual wind turbines (wind farm lay-out). The model calculates the mean wind velocity at every desired position. Using these velocities the power output of each turbine can be determined together with the maximum mean shear across a rotor disc (important for assessment of additional loads). The possible uses of the model are illustrated by two different applications. This wake-interaction model has been applied to a proposed Dutch wind-hydro project. One of the possible lay-outs of the project consists of a circular shaped dike enclosing a vast amount of water. Wind turbines placed on this dike will be used to raise the water level in the artificial lake, creating a storage of energy. Using the wake-interaction model several array configurations have been investigated with emphasis on power reduction and additional loading. The second application concerns rectangular wind farms. A graph has been constructed from which the power output of a given wind farm can be evaluated as  More>>
