The General Design Of 150KW Tidal Current Power Station

Since the 21st century, energy and environment issues have been the problem which must be considered in the current world. More and more country have been focus on the development of new energy resources around world, and positively putted into the development of clean energy with the features of low-carbon emission. Ocean current energy is a kind of clean renewable energy with high value and great potential. In the new century, the energy has continuous developed. Tidal current energy must play an important role, so the development and exploitation of tidal current energy has become the focus of attention in our country even all the world. China has quite a long coastline which contains rich marine resources, so development and exploitation of ocean energy has become our most important task.At present, model running tidal current stations which have been built in the world have several basic forms, which are floating structures, suspended structures, seabed piled structures and sit seabed structures, meanwhile it selects a special carrier as a working platform for turbine and generating units. This paper is based on the National Key Technology Research and Development project about current station contract index and according as hydrological information about Rongcheng sea area, to design a rectangle frame turbine carrier platform, installed capacity of 150KW station. The work in this paper is one kind of exploration about carrier platform for large-scale, and conclusion reached to provide technical sustain and contrast value reference to this project of design and research.This paper proposed platform type of design program first, draw general arrangement plan, determined platform principal dimensions according to the requirement, and estimated platform with weight, center of gravity, displacement. Accurately forecasting the platform' load play an important role in platform structural check. The paper first calculates environment's load as criterions. Then turbine's load and moments are based on momentum theory and stream tube method calculated. Paper is base on the static analysis method for the mooring system. According to the different length and angle of mooring lines, it proposed several kinds of schemes about mooring lines. Finally the paper will get the optimized one as mechanical characteristics.
