Validation of the inflow and wind turbine models in complex terrain


A research test field with two research wind turbines and four measuring masts is being built in the Swabian Alb. Contrary to classical wind energy sites in flat landscapes, this southern German research test field is located at the upper end of a slope and thus in complex terrain. The research test site was realized within the WINSENT project and numerical models of the turbines and the inflow were developed. In the WINSENTvalid project, the numerical models of the incoming flow and the research wind turbines are validated with the help of the measurement data collected on the test field. The validation is carried out in several steps. First, the individual components of the turbines are checked. Then, comparisons are made between simulations and measurements of the turbines in operation.
