Abstract
Wind data are fundamental and indispensable information for the design of wind power facilities. Cup anemometers are classical tools but still now widely used practically for measuring wind. However, it should be noted that the cup anemometer has a mechanical rotation system which has poor response behavior in the fluctuating wind.
In this report, frequency response performance of cup anemometer is studied. A linearized model for the cup anemometer is proposed for describing its power attenuation in the high frequency dynamics. The model is verified by numerical simulation and compared with real field wind data using spectrum analysis. A simple compensation method of cup anemometer is also proposed to improve its dynamic performance.
