The Concept Design Of Platform Which Wind Power Integrated With Desalination And The Analysis Of Its Hydrodynamic Performance

The south China sea is rich in offshore wind resources, offshore wind power can solve the problem of the power lackage on islands in the south China sea.In our country,seawater desalination technology is also very mature, provides technical basis for the people on the island to realize direct use of fresh water which provided by seawater desalination.However, offshore wind power and desalination is a complex integration technology.Therefore, in order to accelerate the actual control of the south China sea, realize ocean development strategy in our country, we must quickly develop floating wind power and desalination integration platform which has independent intellectual property rights.In this paper, take floating wind power and desalination integration platform which is located in a reef in the south China sea as the background, carry on the preliminary design for the platform,based on the three dimensional potential theory, hydrodynamic analysis of integration platform is researched with a software which called AQWA.The main research contents and the major works of this paper can be summarized as follows:(1) Based on the reef situation in the south China sea, on the basis of a typical three floating bodies platform model to improve design platform,carry on a preliminary concept design, this paper introduces the advantages of the integration platform and basic working principle.Select the referred wind turbine and give the basic parameters of the platform according to the island.At last, three floating bodies platform is given two different types of mooring design parameters.(2) Respectively floating wind turbine integration platform which is with tendon mooring and taut mooring as the research objects,set up the hydrodynamic model, call AQWA- LINE module,the hydrodynamic parameters of floating platform under frequency domain of regular wave and the change rule of parameters in the different angle of incidence situation are obtained.Lay the foundation for nonlinear coupling analysis under time domain,and under various extreme conditions in the south China sea,calculate the response of the six degrees of freedom and mooring force of integration platform.At the same time, strip analysis for the results of the response,get the contributions for the different frequency components of motion response.(3) Through the comparative analysis of motion response of three floating bodies platform under two types of mooring,conclude that tendon mooring is the better scheme.
