A Study on Power Cable Loads for a Floating Ocean Current Turbine

浮遊式海流発電装置の電力ケーブル荷重に関する研究

This paper discusses power cable loads for a floating ocean current turbine. The floating ocean current turbine is supposed to have unique motion characteristics, which causes unknown loads to the power cable. In this study, two severe situations and three candidates of cable configuration have been considered. In one of these situations, the cable shows unique motion due to bend & torsion moment. To confirm the accuracy of numerical calculation in this situation, calculation by two methods and an experiment are performed. In addition, theoretical analysis is performed to interpret the reason of the motion. The results show that the FEM analysis agrees well with the experiment, and that the cable motion is interpreted as energy shift from bending to torsion energy. Therefore, full scale calculation is performed using the FEM program. The results show that floater style with vertical connector is the most suitable cable configuration for the floating ocean current turbine and the maximum loads do not exceed 15% of allowable loads of the power cable even in the severe situations.
