Abstract:The wind resources of the Jimo wind farm are analyzed and the representative years are determined by means of the 30-year wind data from Jimo Weather Station and the wind measurements from a meteorological observation tower. Tests and emendation are conducted according to the related technical stipulations. Analyses and computation are made of the wind energy parameters measured at the tower such as the daily and annual variation of wind speed, the monthly and annual variation of wind direction frequencies, the mean wind and wind power density, effective hours of wind speed, etc., as well as the power output and its variation regularities with height for various wind turbines. It is concluded that it is worthy of development only when the winds reach Grade 3 on the Beaufort scale for a wind farm.
