Development of Innovative High Efficiency Wave Power Generation System

设计了适合该系统安装海域的发电机结构。用有限元方法对发电机进行了分析，计算了系统的各种特性。在采用8倍速直连机构和12极SPMSG的条件下，平均能量转换效率不受安装海域面积的影响，最大为20%。结果表明，与传统的波浪发电系统相比，该系统的转换效率提高了数倍甚至更多。此外，对于发电机的扭矩指令模式，将扭矩指令切换到两个阶段的方法对发电量的改善最大。与使用恒力矩指令的情况相比，发电量增加了3-6%。

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.
