Wind data analysis and a case study of wind power generation in Hong Kong

This paper analyses wind speed data for five typical sites in Hong Kong in terms of site terrain, wind conditions and wind power potential. For onshore and offshore wind power resources, the annual, monthly and diurnal wind speeds are assessed, and the annual mean power densities for the five sites are also calculated. These may be used for optimum sitting of wind sites in Hong Kong, which is also discussed for practical application. The characteristics and power output of a chosen wind turbine on one island are modelled and analysed as a case study to assess the wind power potential. The capacity factor of the modelled wind turbine reaches nearly 0.36, which is considered significant for wind power application. The example demonstrates that the sites on islands with good exposure are attractive for generating wind power, and that therefore offshore should be considered.
