Wind turbine wake mathematical models validation by means of wind field data

The present paper deals with a study of wind turbine performance taking into account wind turbine interaction in wind farms. In more details, a wake mathematical model, based on Jensen/Katic theory, was implemented and used to evaluate velocity deficit at the downstream turbine. In order to test and verify wake mathematical model implementation, wind farm real data were used. Turbines in pairs data were extracted from wind farm monitoring system and were elaborated to collect wind characteristics (wind intensity and direction), as well as turbines’ powers and wind intensity at the turbines’ nacelles. On the basis of the presented results, the implemented mathematical model is able to correctly estimate velocity deficit while errors on downstream power were lower than 10 % in all cases. Therefore, the model is validated.
