Hardware-in-the-loop testing for tidal energy power conversion systems

A hardware-in-the-loop approach to test tidal energy power conversion systems is presented. Typical tidal conditions are replicated using a prime mover driven by a tidal turbine real-time simulation. The power conversion equipment and its control are then connected to an artificial grid. The approach is validated with experimental results for a full tidal cycle using a maximum power tracking controller. The test-rig serves as a first step within a systematic development process leading to commercial tidal power conversion systems.
