Study On Load And Motion Response Of Tidal Current Energy Wind Energy Complementary Power Generation Device

Marine energy resources are huge in the ocean.It will be the focus to develop and utilize in china.The tidal current energy and wind energy,whose marine energy`s reserve is relatively rich is mainly distributed in the sea area of 5km~50km.And these areas are relatively deep and taking into account the questions of costs,bottom type foundation has been unable to complete the corresponding task.In order to fully exploit and utilize the ocean energy resources,to improve the power generation and to develop the blue economy,it is of great significance to study the load and the motion response of the offshore floating tidal current.In this paper,based on the trend of the development and utilization of marine energy resources,the history and current situation of wind energy utilization in various countries are compared,and the important significance of the development of wind energy and wind energy is proposed.At the same time,the floating body which is based on the three floating structure designed by predecessors was improved,and the load is added on the floating body to which tidal current energy turbine and wind turbine in the normal working time transmit.What`s more,the structure and hydrodynamic performance of the floating body is analyzed.The floating tidal power wind power generation device studied in this paper is mainly composed of vertical axis tidal current turbine,wind turbine and tower body connected with power generator etc..So the order in this paper is hydrodynamic performance of vertical axis turbine firstly,the aerodynamic performance of horizontal axis wind turbine secondly,load and motion response of floating foundation coupled with two power generation device.The research and design of the device can provide the necessary reference for the development and utilization of tidal current energy and wind energy resources in the fields of offshore and deep sea in the future.
