    Abstract: The accuracy of state stimulation of the wind resource condition mainly reflects in the time interval of the wind measurement data.This research obtained the wind measurement data per 10 min of the anemometer tower of the wind farm in Huai'an for more than one year. In addition,it used the least square method, average wind speed, standard deviation estimation method, and maximum likelihood estimation to evaluate the recorded data of the time interval(30 min/1 h/2 h), solve wind speed probability distribution, conduct the productivity evaluation, and compare estimation errors of generating capacity in the different time interval. The result shows that the estimation error of the generating capacity enlarges with the time-scale increasing. The generating capacity calculated by the wind measurement data per 30 min is close to the computed result of the data per 10 min. All in all, the result has instructional functions when the wind measurement data of the wind farm has poor integrity.
    Key words: wind measurement data; time interval; Weibull parameter; productivity evaluation
