ABSTRACT
During the last half a dozen years numerical flow models and other advanced computational tools have became widespread in the wind energy community. One such collection of computer tools is the Wind Atlas Analysis and Application Program (WAS P) which was developed during the investigation leading to the European Wind Atlas. As the name indicates the program is used mainly for two purposes: establishing of regional wind climatologies, i.e. wind atlases and micro-siting, i.e. determination of optimum wind turbine sites in specific areas. For countries where a national wind atlas exists the common siting procedure is to select the proper wind atlas statistics and further to acquire a set of meteorological data from the nearest meteorological station. Comparisons of wind data measured at meteorological stations, as well as actual power productions measured over several years in Denmark and southern Sweden, have shown that WAS P performs very well in relatively uncomplicated topography.
