KIOST Tidal Energy Converter

The project is aimed to develop and demonstrate the active-controlled, high efficiency and low cost 200 kW Tidal Energy Converter (TEC), with the operating capacity applicable to the shallow sea conditions (about 20 m). The TEC was manufactured by KIOST and its caisson-type substructure was designed, fabricated, and deployed by Hyundai Engineering and Construction 2016. In 2017, the performance of PMSG and main drive train was evaluated using a portable dynamo test facility, and the internal communication system and the active rudder device for automatic and passive yaw control have been also tested in indoor and underwater environments. The TEC will be installed at the Uldolmok test site for open sea test in early 2018
