| 1 | 半潜式风流联合发电装置水动力性能分析显示文摘文章基于半潜式风流联合发电装置,以频域势流理论为基础,研究风流联合发电装置的频域水动力性能,得到了漂浮式载体在规则波中的运动响应RAO和水动力系数;根据载体频域分析结果、水轮机CFD数值模拟结果及风力机载荷特性确定装置的风、浪、流等载荷,利用Fortran编程对AQWA进行二次开发,计入附加的定常力及非定常力,并以此计算极限工况(破损自存工况)下,不规则波中的系统运动响应和系泊线张力。计算结果表明,该半潜式风流联合发电装置在极限工况下具有良好的水动力性能,设计安全可靠。 | 周丙浩 和禹含 马勇 胡超 徐颜 | 2018 | 可再生能源2018,36,8: | 3 |
| 2 | 半潜式风、潮流联合发电平台水动力分析(英文)显示文摘Energy shortages and environmental pollution are becoming increasingly severe globally. The exploitation and utilization of renewable energy have become an effective way to alleviate these problems. To improve power production capacity, power output quality, and cost effectiveness, comprehensive marine energy utilization has become an inevitable trend in marine energy development. Based on a semi-submersible wind-tidal combined power generation device,a three-dimensional frequency domain potential flow theory is used to study the hydrodynamic performance of such a device. For this study, the RAOs and hydrodynamic coefficients of the floating carrier platform to the regular wave were obtained. The influence of the tidal turbine on the platform in terms of frequency domain was considered as added mass and damping. The direct load of the tidal turbine was obtained by CFX.FORTRAN software was used for the second development of adaptive query workload aware software, which can include the external force. The motion response of the platform to the irregular wave and the tension of the mooring line were calculated under the limiting condition(one mooring line breakage). The results showed that the motion response of the carrier to the surge and sway direction is more intense, but the swing amplitude is within the acceptable range. Even in the worst case scenario, the balance position of the platform was still in the positioning range, which met the requirements of the working sea area. The safety factor of the mooring line tension also complied with the requirements of the design specification. Therefore, it was found that the hydrodynamic performance and motion responses of a semi-submersible wind-tidal combined power generation device can meet the power generation requirements under all design conditions, and the device presents a reliable power generation system. | 马勇 胡超 周丙浩 李磊 康有为 | 2019 | Journal of Marine Science and Application2019,18,1: | 0 |
