摘　　要：提出了一种新颖的风浪能组合系统,该系统由半潜式风机和阵列式环状点吸式WEC组成。基于三维势流理论,研究了不同WEC数量的配置对风浪能组合系统的稳定性和发电性能的影响。结果表明:在北海海域下,C_(1)、C_(2)和C_(3)配置的组合系统的纵摇均值分别达到2.39°、2.36°和2.34°,纵摇标准差分别为0.724°、0.715°和0.711°。与C_(1)配置相比,C_(3)配置的均值和标准差分别降低了2.09%和1.80%。随着WEC数量的增加,WEC阵列的总平均功率也随之增加并且平均单个WEC的发电功率也在增加。C_(3)配置下的组合系统中的每个WEC发电功率平均值较C_(1)配置和C_(2)配置分别提高了1.4%和0.44%。A novel concept of combined wind-wave energy system was proposed,which consisted of a semi-submersible floating wind turbine and an array of point absorber WECs.Based on the three-dimensional potential flow theory,the effects of different configurations of the number of WECs on the stability and power performance of the combined system were investigated.The results show that,in the North Sea,the mean value of pitch motion of the combined system with C_(1),C_(2) and C_(3) configurations reaches 2.39°,2.36°and 2.34°,respectively.The standard deviation of the pitch motion is 0.724°,0.715°and 0.711°,respectively.The mean value and standard deviation of pitch motion with C_(3) configuration is reduced by 2.09%and 1.80%compared with that with C_(1) configuration,respectively.As the number of WECs increases,the total average power of the WEC array increases and the average power generated by per WEC also increases.The average power generated by each WEC in the C_(3) configuration increases by 1.4%and 0.44%compared to the C_(1) and C_(2) configurations,respectively.
