The Research Of Floating Photovoltaic Power Station In Ludila Reservoir

Floating photovoltaic power station can work under the water over three metres.It can be built in any place with water,which deals with the problem—photovoltaic power station can't be built in profundal zone.There are still many unsolved problems in the construction of floating photovoltaic power station:the life span of basic floating materials,connecting intensity between floating foundation,the reliable fixation of floating foundation in profundal zone and water areas with large water-head,economic feasibility and so on.The thesis targets on the model of Ludila floating photovoltaic power station from four aspects:basic floating materials,connecting intensity between floating foundation,the reliable fixation of floating foundation and economic feasibility.The research adopts the methods of building models,force analysis,simulation,finite element analysis and economic feasibility analysis in order to provide references to address the technical and economic problems in constructing floating photovoltaic power station.The thesis adopts the following methods:hydrodynamics,meteorology,PVSYST,AutoCAD,Pro-E3D,ANSYSworkbench and ecnomic evaluation software.The data are from professional database:Meteonorm and NASA.Therefore,the the caculation methods are reliable and the data are full and accurate.The thesis intends to solve the following problems:(1)Using modified PE materials as floating foundation can meet the requirements of extending the life span of floating photovoltaic power station for over 20 years.(2)The influence of limit wind pressure on floating photovoltaic power station can be controlled by comprehensive fixed methods.The factor of water flow can be neglected.(3)The thesis designs a plan about the floating photovoltaic power station,including the structure of floating foundation,the connectionmode of floating foundation and the fixed mode of floating foundation under the water.(4)Throughsimulation analysis,the structure intensity of the floating photovoltaic power station meets the requirement.(5)The cost structure of floating photovoltaic power station is based on the analysis of actual situation.After the economic analysis,we can conclude that the floating photovoltaic power station is economically feasible with investment value at this stage.(6)The thesis tests the validity of the floating photovoltaic power station through the practical operation of the pilot power station.The generating capacity meets the expectation and the investment value is higher than the land photovoltaic power station.
