The electrical properties of wind turbines are to be certified in accordance with the relevant guidelines on system test benches. The test methods can be validated by comparing the test bench results with the field data. BMWi, 06/2017 – 05/2020

The primary objective of the “WindUC” project is to develop mathematical models of the next generation of wind turbines for use during the control unit design phase. In a second phase, these models will then be used to modify or redesign and test advanced control algorithms. The suitability of the novel procedures is then to be tested using real-time simulations. BMWi, 04/2015 - 01/2020

Application of hydro-acoustic methods for the detection of buried objects in the sea floor in the course of the planning of offshore wind farms and cable routes. BMWi, 12/2016 – 05/2020

When designing the aerodynamics of wind turbines, the force coefficients of aerodynamic 2D profiles, so-called polars, are mostly used. In the Extrapol360 project, the development of a method for extrapolation of the polars of thick profiles for an angle range of 360° is planned. BMWi, 06/2018 - 12/2020

The segmentation of very long and very thin rotor blades offers great potential for facilitating their production, transport, and installation. An innovative joining technique is now being tested on segmented blades. The joining technique is being analyzed and its structural mechanics validated on a 20-meter- and a 50-meter-long rotor blade. BMWi, 01/2017 - 06/2020

The project aims at improving the design process of offshore support structures by considering sea ice loads in a coupled numerical analysis. This will be realized by combining advanced ice models with aero-hydro-servo-elastic simulation tools. BMWi, 05/2016 - 01/2020

Active influencing and control of the flow dynamics of rotor blades has the potential to increase the energy yield of a wind turbine. The effect induced by fluid actuators integrated in structures is determined in flow simulations and considered in relation to the additional costs. BMWi, 8/2017 - 7/2020

The investigation of passive technologies for load reduction by means of both experimental activities at test-rig and measurements on a test turbine with Bend-Twist-Coupling blades are focus of the project. The results from the previous project were validated; moreover, new phenomena arising from the coupling are taken into account. BMWi, 06/2016 - 06/2020

An integral tower concept will be developed and extensively examined in the support structure test center: for example, the buckling behavior will be tested on small- and large-scale braced test specimens subject to static axial and bending loads on the span field. BMWi, 03/2016 - 12/2020

The aim of the project is to develop an innovative multi-terminal HDVC concept for the electrical connection of multiple offshore wind farms to the onshore transmission network. The first step is the analysis of the known connection options for offshore wind turbines via alternating current to direct current and point-to-point direct-current transmission systems. The results of the analysis are integrated in the design and development of a scaled demonstrator. BMWi, 10/2017 - 09/2020
