The WindScanner facility is a unique, distributed research infrastructure that will provide fundamentally new knowledge about the wind and will lead to more efficient, stronger and lighter wind turbines. Exploiting recent advances in laser wind measurement techniques, mobile 3-D remote sensing wind scanners will be deployed by seven large energy research institutes across Europe. This will provide an important catalysis to the future cooperation and integration of the European wind energy research infrastructures.
The WindScanner.eu project aims to be an Open Access distributed and mobile research infrastructure promoting the dissemination of results including innovation products and their exploitation. WindScanners are based on portable and easy deployable wind lidars and wind scanners and be operated and interconnected throughout Europe via fast, scientific computer networks.
It is a scientific challenge to measure and understand the three-dimensional and time varying wind field as it passes through and interacts with the huge rotor of a modern wind turbine. Using traditional wind measurements made by anemometers mounted on meteorological masts, it is practically impossible to acquire the necessary 3-D wind information. Our present comprehension of the turbulent wind flow and its interaction with wind turbines is correspondingly limited.
The operation of WindScanner systems present significant challenges in data management. An operational WindScanner will generate enormous amounts of data, requiring a well-defined database structure and organization of access. It is required to streamline the huge amounts of measurement data. In Big-Data-Europe the possibilities for supporting WindScanner through the tailoring of BDE pilot case platform are under investigation.
Due to its full-scale measurement methodology, WindScanners provide lower uncertainty than alternative wind tunnel scale testing or computer modelling. The results obtained will foster improved computer models and permit a more optimal design of wind turbines. Ultimately, this will lead to better located, better wind turbines thus reducing the cost of renewable energy.
The RES directive demands a high rate of deployment of renewable energy, to which wind is expected to contribute significantly. This demand corresponds approximately to the installation of one large turbine every hour for the next decade. WindScanner contributes to the realization of the SET-plan goals by establishing this new and truly distributed European facility. With a central node in Denmark, the core consortium consists of seven partners from the European Energy Research Alliance (EERA). Researchers and industry will have open access to the WindScanner infrastructure, accelerating technological innovation, exchange and synergy between the European R&D institutes and the wind energy industry.
