近几十年来，可再生能源一直受到世界各地科学家的关注。海流也有望成为一种新的可再生能源，并开发了一些类型的海流涡轮机。为了优化洋流涡轮机设计，利用流速信息是必不可少的，但事实是，关于流速的信息很少，并且没有很好地组织。因此，本文提出了一种基于功率谱模型的海流信息组织和利用方法。此外，还考虑了资料缺乏的观测系统，在黑潮流域附近进行了现场观测。因此，波动强度范围量化在观察到的位置，并通过应用当前的速度复制从建议的频谱模型，设计评估的数值模拟变得更容易。作为算例，对叶片上的载荷进行了时域估算，为叶片的设计提供了依据。
Renewable energy has been an attention of scientists for last few decades around the world. Ocean current is also expected to be a new source of renewable energy and some types of Ocean Current Turbine is developed. For optimum ocean current turbine design, utilizing current velocity information is essential but the fact is that there is little information about current velocity and it is not organized well. Thus, in this study, a method to organize and utilize ocean current information based on power spectral model is proposed. Moreover, observation system for lack of data is considered and in-situ observation is conducted around the Kuroshio watershed area. As a result, fluctuation intensity range is quantified at the observed location and by applying current velocity reproduced from proposed spectral model, numerical simulation for design assessment gets easier. The load on the blade in time domain is estimated as an example and it would be used for the design.
