| Research Abstract |
A suitable structure of generator for the installation sea area of the system was designed. The generator was analyzed by using the finite element method, and various characteristics of the system were calculated. In the condition to use the direct link mechanism of a multiplying gear of 8 and the 12-pole SPMSG, the average energy conversion efficiency did not depend on the difference of the installation sea area and was the maximum 20%. It was shown that the conversion efficiency became several times or more compared with a conventional wave power generation system. Moreover, the generated electric power has been improved most in the method to switch the torque command to two stages for the torque command pattern of the generator. The generated electric power has increased by 3-6% compared with the case to use the constant torque command.
