Abstract

In order to efficiently utilize marine resources and promote the development of multi-energy integrated floating platform, a "wind turbine-photovoltaic-net cage" floating integrated platform is proposed to adapt the deep-sea application. Based on the coupled calculation method of FAST and AQWA, the integral numerical model of wind turbine, photovoltaic （PV） and net cage platform, mooring system was established. The influence of the PV module on the hydrodynamic performance of the integrated platform was investigated by comparing the frequency domain of "PV-net cage" integrated model and single net cage model. Considering the combined actions of winds, waves and currents, the dynamic responses of the "wind turbine-photovoltaic-net cage" floating integrated platform was further calculated. The results show that PV module causes the increase of the additional mass and the peak radiation damping of the integrated model, and has little effect on the first-order wave force but leads to the augment of the RAO in the direction of the heave and the pitch. Under combined actions of winds, waves and currents, the rotor thrust, blade tip flapping deviation, base shear force and tower top deviation of the wind turbine produce large fluctuations. The responses amplitudes of the PV and the net cage platform in the surge and pitch direction significantly increase, but slightly influences on the heave direction. Meanwhile, the axial tension of the windward platform cables remarkably amplifies, and the axial tension of the leeward platform cables reduces. Compared with the single cage platform, the addition of wind turbine and photovoltaic module will also increase the upwind cable tension and decrease the leeward cable tension of the floating integrated platform.
