Modeling and SIL simulation of a Tidal Stream device for marine energy conversion

摘要

This paper deals with the development and simulation of a MATLAB/Simulink model of a Tidal Stream Converter (TSC) to be installed in the breakwater at the harbour of Mutriku on the Basque coast in Spain. The developed model is that of a three-bladed tidal turbine connected to a Doubly Fed Induction Generator (DFIG) for marine energy convertion. A Software-In-the-Loop (SIL) simulation of the established TSC model has been investigated using the NI VeriStand tool. This is achieved in order to prepare for the Hardware-In-the-Loop (HIL) implementation of the studied marine energy converter based on an NI Compact RIO real-time target. All simulation results, obtained by MATLAB/Simulink within a Model-In-the Loop (MIL) simulation framework and by NI VeriStand within SIL simulation one, are analyzed and compared in order to validate the developed TSC model.
