SAMESHIMA Shigemichi, a second-year master’s student on the Electrical Engineering Program, Graduate School of Science and Technology (KUMANO Teruhisa Laboratory), received an incentive prize, the YOC (Young engineer Oral presentation Competition) for his presentation at the IEEJ Power and Energy Society.
In this paper, a new system different from the conventional one is proposed for a large-scale offshore wind farm that will be key to the development of renewable energy for the future in Japan. In large-scale wind power generation, permanent magnet synchronous machines are used instead of the gearboxes used in conventional generators owing to their high output.
The electricity generated here is converted to direct current (DC), then back to alternating current (AC) before being connected to the power lines. In SAMESHIMA's presentation, a system was proposed in which the electricity is transmitted in the form of DC tens of kilometers to the shore, and then converted to AC via an M-G set driven by a direct current machine, and the effectiveness of this system was evaluated quantitatively.
