Studies on achieving higher output of tidal power generation system with multi-rotor

如果在水流速度较快的地点安装潮汐和海流发电系统，与其他发电系统相比，可以降低发电成本。然而，在日本海岸周围的浅水区，像这样的合适地点是有限的。在这项研究中，我们研究了一个具有多转子系统的高功率潮汐和海流发电系统。为了保证一定的发电量在1.0m/S左右的流速下发电，潮汐和海流发电系统在日本沿海地区得到广泛应用是非常重要的。对于多转子系统，后转子可以收集从前转子传递的流动能量。对多转子系统进行了基础性研究和概念设计。

If tidal and ocean current power system can be installed in site where the flow velocity is fast, it may be able to reduce the power generation cost compared with other power generation system. However, suitable sites like this in shallow water around the coast of Japan are restricted. In this study, we investigate a high power tidal and ocean current power system with a multi rotor system. It is important for the tidal and ocean current power generation system to utilize widely in the coastal area of Japan in order to ensure a certain amount of power generated at about 1.0m / s flow velocity. For the multi-rotor system, the back rotor can be collected the flow energy passed from the front rotor. We perform a fundamental study and concept design for multi rotor system.
