Abstract: Renewable energy sources, especially wind turbine generators, are considered as important generation alternatives in electric power systems due to their non-exhausted nature and benign environmental effects. The main task of a professional wind measurement, used for wind power generation application, are wind measurement for accuracy and reliability of measuring needed for profit prognosis and wind measurement for the monitoring of already installed wind farms.In this paper present Before the installation of a wind turbine or farm it is recommended to analyse the site professionally. The collected meteorological data should accurately describe the wind potential of the site. That is why the measuring systems should meet the highest quantity demand concerning the accuracy and reliabilityThis study shows the probabilistic analysis of wind power generation from wind turbine generators installed at geographic locations.
