Development of Innovative High Efficiency Wave Power Generation System

设计了适合系统安装海域的发电机结构。采用有限元法对发电机进行了分析，计算了系统的各种特性。在使用8倍齿轮的直接连接机构和12极SPMSG的情况下，平均能量转换效率不依赖于安装海域的差异，并且最大为20%。结果表明，与传统的波浪发电系统相比，转换效率变为几倍或更多。此外，在将转矩指令切换为发电机的转矩指令模式的两个阶段的方法中，发电电力的改善最大。与使用恒定转矩指令的情况相比，发电功率增加了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.
