摘　　要：提出通过浮子形状和排布结构的优化,提高直驱式波浪发电系统(DDWEC)的能量吸收效率,并改善输出功率波动问题。文中推导分析了DDWEC水动力模型,提出了水动力参数的优化原则,根据优化原则提出了浮子形状的优化措施,采用WAMIT软件仿真验证了对提高能量吸收效率的有效性;同时,基于浮子优化结果,在考虑浮子间互相影响的情况下,通过波浪发电场的排布结构优化,改善了DDWEC功率波动的问题,削弱了遮蔽效应等浮子间的影响,提高了波浪发电场的能量吸收效率。In this paper , the optimizations of buoy shape and array geometry are studied to improve the energy ab-sorption efficiency of direct-drive wave energy converter （ DDWEC ） and to smooth the output power fluctuations . The hydrodynamic model of DDWEC is derived and analyzed , therefore , the optimization rules of hydrodynamic pa-rameters are summarized .Based on the rules , the optimization measures of buoy shape are proposed , and then the hydrodynamic software WAMIT is used to simulate and verify the improvement of the energy absorption efficiency . Meanwhile , considering buoys interactions , the array geometry of wave farm is optimized to mitigate power fluctua-tions and weaken the buoys interactions （ such as shadowing effect ） , based on the optimization results of buoy shape.As a result, the energy absorption of wave farm is increased .
