摘要
本文对同轴双浮子波能发电装置进行了深入研究。采用Fortran语言对AQWA进行二次开发,并施以线性及非线性PTO反力,实现了装置的运动模拟,获得了双浮子装置的水动力特性及捕能情况。研究表明,波浪周期及内外浮子质量对装置获能影响显著,建议选用质量比为0.8的双浮子装置,并将其放置于周期与外浮子固有周期接近的海域中以实现最优捕能。
The double-body heave converter is one of the most conducive devices to absorb the wave energy from relative motion.This paper makes an in-depth study on this wave energy converter,by means of numerical simulation.The linear and non-linear PTO reaction force is applied by the secondary development of AQWA through the Fortran language to realize the motion simulation of the device,and the hydrodynamic characteristics and energy capture of the double-buoy are investigated.Results show that the wave period and mass of the buoys have a significant effect on the converter.It is recommended to select the double-buoy converter with a mass ratio of 0.8 and to place it in an area with the frequent wave period close to the natural period of the outer buoy to achieve the optimal energy capture.
