Abstract
Recently, the horizontal axis tidal turbine (HAT) have numerous attentions as systems extracting sustainable and predictable renewable energy, but a commercial power generation in an array form is not started yet due to technical, financial, and environmental uncertainties. In technical aspects, the power efficiency would be critical problem for the success in the tidal current generation. One of the appropriate approaches, an active control is a powerful approach for achieving the high efficiency as well as the safe operation in the conditions of the variable direction and the variable speed of the tidal current even though the complexity of the turbine systems increases. Therefore, this study is focused on the development of an active controller in the tidal current turbines. In order to validate our new active-control concept, we conducted the indoor experiments of a 1/15 scale turbine model including the active controller. The effect of the yaw control on the power efficiency was analyzed and minute yaw control as well as 180 degree turn by the controller was demonstrated. Based on the results of this study, the full-scale model of 200 kW capacity will be fabricated and be validated by out-door tests.
