Description: Das Projekt "Windtec 1200 kW-cost/light-weight wind turbine" wird vom Umweltbundesamt gefördert und von Windtest Kaiser-Wilhelm-Koog durchgeführt. General Information/Objectives: The objective of the project is to develop a 3-bladed, 1.2 MW, variable speed, pitch controlled wind turbine, with (a) reduced tower head mass, (b) optimized energy yield for low wind speed regimes, and (c) improved logistics with strong emphasis on the erection of the turbine without crane. The combination of all these improvements are expected to lead to reduced costs of power production, whereby the goal is to produce electrical power for 0.038 ECU/kWh in a wind regime of 8 m/s at a hub height of 60 m. Technical Approach Above objectives are achieved by developing various new components as: (1) Improved variable speed power electrics on the basis of a doubly fed induction generator. (2) Integrated drive train design with the main target of reducing weight and costs. (3) Light weight rotor blade design, utilizing carbon fibre technology. (4) Optimized slip-form concrete tower designed to reduce costs and to improve the dynamics of the complete system. (5) Modular nacelle design including an on-board erectable crane system, which allows the nacelle and the rotor to be installed without an external mobile crane. After the engineering phase a prototype will be manufactured and installed in the eastern part of Austria. Loads and performance measurements will be performed and reported under the Scientific Measurement and Evaluation Programme (SMEP), which was developed for the WEGA-II machines. The analysis of the measurements will be the basis for (a) the validation of the design and the performance of the wind turbine, and (b) further improvements of the design. Expected Achievements and Exploitation The expected outputs of the project are: (1) Validation of software programs by comparing dynamic simulations with measurements. (2) Development of a variable speed power electrics system, which is highly efficient and at the same time very cost effective. (3) Development of a light weight rotor blade with high aerodynamic efficiency. (4) Improvement of the logistics for the installation of a MW-class wind turbine. The combination of all these features should lead to a wind turbine with substantially improved economics by guaranteeing excellent power quality.
