Acoustic instrumentation deployment on and around the Sabella D10 turbine to capture parameters to contribute to site characterisation, measurement and modelling tools.
A new BEMT tool, christened as ‘StarBlades’, has been developed within RealTide project, which computes the forces on a tidal turbine in realistic inflow conditions.
Due to their recent introduction there are very few data available on the mechanical response of full scale tidal turbine blades. This lack of knowledge leads to uncertainty in design and was addressed in WP4.4. Better understanding of the blade response and its limits should contribute to improved turbine reliability. IFREMER worked with Sabella to design a specific test facility and then collaborated with EnerOcean and Bureau Veritas in developing specific instrumentation.
The development of a whole system, fully-coupled model of a laboratory-scale hydrokinetic tidal turbine, along with its interactions with the ocean environment and its electrical control system is presented (The University of Edinburgh). The model was developed using Computational Fluid Dynamics, Large Eddy Simulation and Actuator Line Method coupled with an external torque control system. The control system is developed from the optimal torque speed curve based Maximum Power Point Tracking algorithm.
