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.　©　2025　Science　Press.　All　rights　reserved.
