基于势流理论的浮式潮流能电站载体耐波性分析

摘要

Based on 3D potential theory, involved impact from tidal turbine to floating barge, the sea-keeping performance of a floating tidal turbine was calculated and analyzed by Hydrostar, a general analysis program for calculation of wave-structure interaction. Besides, the short-term prediction of the sea keeping of the ship was done related to the extreme sea state in the work site. The calculation results show that the rolling motion of the floating barge is relatively violent in beam sea and shipping of green water tends to occur in bow sea.%基于三维势流理论，考虑水轮机对载体的影响，运用 Hydrostar 计算评估某浮式潮流电站载体的耐波性。并结合潮流电站工作当地极限海况，对该载体的耐波性进行短期预报。计算结果表明，该潮流电站浮式载体横浪状态下横摇响应大；在迎浪状态下，潮流电站浮式载体最容易甲板上浪。
