Implementation of Permanent-Magnet Synchronous Generator for Applying to a MCT System

摘要

In this paper, a low-speed high-efficiency PMSG machine with small cogging torque has been implemented rigorously as the generator of a marine current turbine (MCT) system to harvest ocean current power. Furthermore, the proposed PMSG-based MCT system has been developed to investigate its feasibility of ocean current generation system at ocean surrounding of Taiwan. In addition, the MCT system has been tested really in the ocean surrounding Penghu County of Taiwan during the 2013.07.09-11. The experimental results have shown that proposed PMSG machine not only can satisfy the performance requirements but also the PMSG-based MCT system can harvest effectively the ocean current energy.
