With the global economic development in recent years,energy shortage problem is becoming more and more serious all over the world and more attention is paid on the better use of marine renewable energy.Among all the variety of marine renewable energy,tidal power generation technology is relatively mature.At present,the most research work on the utilization of tidal energy is focus on the theoretical calculation,simulation and experimental study on the model turbines in laboratory.In the future,tidal farm is the inevitable choice to achieve large scale industrial development of tidal energy.In order to gain more tidal energy for the purpose of commercial application,one of the best ways is to arrange more turbines in tidal farm.Because of the wake effects on tidal turbines in tidal power farm,the performance of the flow field around of the turbines was changed and has impact on the capture efficiency of electric power.The layout method of the tidal turbines and the longitudinal and lateral distance between turbines can influent the capture efficiency of turbines.Therefore,study on the interaction effects on tidal turbines and the optimization of the layout of the tidal stream turbine array becomes one of the key problem in the construction of tidal power farm,which directly influent the economic benefits of tidal power farm.In order to realize the large scale utilization of tidal power plant,the influence rules of horizontal axis tidal turbines in different layout of tidal turbines based on the real measured data should became one of the research topics.Therefore,rational parameters in tidal farms should be chosen to improve the capture efficiency.Research on the layout method of the tidal turbines is the key issue for planning of the tidal farm.In this paper,according to the real measured data obtained in the exploration of tidal energy resources and the measurement of the geological hydrology for the actual resources,method of layout and planning of tidal turbines in the tidal farm was studied.Tidal farm area combined with the farm's location conditions was selected,design parameters of turbines were determined,turbines were reasonably laid out according to the optimal spacing,turbine number was optimized and generating capacity was predicted.These research works will provide theoretical basis for the construction of tidal power farms in the future.The method used in this paper would be a reference for the development of tidal energy in actual sea,and it would also become the foundation for the large-scale commercial development of tidal energy.
