摘要
为研究水轮机安装位置对Spar式风-流互补系统耦合动力学特性的影响,基于开源软件OpenFAST和商用软件AQWA建立了Spar式风-流互补系统气动-水动-伺服-弹性全耦合仿真模型.运用叶素动量理论、模态法和辐射绕射理论分别计算了水轮机安装于水平面以下-70,-80,-90,-100 和-110 m处的平台运动、系统输出功率及系泊张力,并与无水轮机时的计算结果进行对比分析.结果表明:当水轮机安装于水平面-110 m时,与无水轮机时相比平台纵摇平均值降低了11.57%,系统输出功率增加10.15%,说明Spar式风-流互补系统在提升功率的同时还可以增强系统运动稳定性.
Abstract
In order to investigate the influence of hydroturbine installation position on the dynamics char-acteristics of the Spar integrated wind-current energy system,this paper established a fully coupling aero-dynamic-hydraulic-servo-elastic simulation model of Spar integrated wind-current energy system based on the open-source software OpenFAST and the commercial software AQWA.Using blade element momen-tum theory,modal analysis and diffraction-radiation theory,the platform motion,system output power and mooring tensions were calculated for the cases in which the hydroturbines were installed at 70 m,80 m,90 m,100 m and 110 m below the mean sea level,respectively.The simulation results were ana-lyzed and compared with the calculation results without hydroturbine.The results show that when the hydroturbines are installed at 110 m below the mean sea level,the mean value of the platform pitch is re-duced by 11.57%compared with the results in the case without hydroturbines.The output power of the system increases by 10.15%,indicating that the Spar integrated wind-current energy system is not only capable of improving the power output,but also of enhancing the operational stability of the system.
