摘要
To predict the average power output of a wind turbine, a response model is proposed which takes into account: (i) the delayed response to the longitudinal wind speed fluctuations; (ii) a response function of the turbine with arbitrary frequency dependence; (iii) wind fields of arbitrary turbulence intensity. In the limit of low turbulence intensity, the dynamical ansatz as proposed in 1992 by Rosen and Sheinman is reproduced. It is shown, how the response function of the turbine can be obtained from simulation experiments of a specific wind turbine. For two idealized situations the dynamic effect of fluctuating wind is estimated at turbulence intensities 0 less than or equal to I-u less than or equal to 0.5. At the special mean wind speed V = 8 m/s, the turbine response function is determined from simulation data published by Sheinman and Rosen in 1992 and 1994. (C) 2003 Elsevier Ltd.
