Research on the wind energy test field in complex terrain


Within the framework of the project a fully functional wind energy test site in complex mountainous terrain is constructed. The test site location has already been identified within the KonTest project (Fkz. 0325656 A-D). The test site offers both a real and a virtual environment as well as testing new technologies and control strategies to anaylse the dynamic behavior of wind turbines in complex terrain. Furthermore, new technologies and control strategies can be tested. Therefor, the open platform supports the use of wind energy in complex terrain through improved prediction of performance and turbine load as well as through yield increase and load reduction. Besides the Coordination the project includes: Construction and Operation, Microclimate and FoWEA.
