Abstract
Solar and wind energy which is the inexhaustible green energy is harmless to the Earth's environment and. In recent years, the solar and wind power generation have been a lot of development, but most of the solar power generation is limited to the flat-panel photovoltaic power generation, without using focusing sunlight and splitting spectrum techniques. And power generation using gathering wind is even more less. Both of them have the drawback of discontinuous generation and can-not be exploited at the same time and place. Therefore, this thesis aims to do exploratory research on key techniques of the integrated power generation with split-spectrum focusing sunlight and gathering wind, introducing splitting spectrum and gathering wind technologies into concentrating photovoltaic power generation.
At the beginning, this thesis describes the basic process of split-spectrum concentrating photovoltaic power generation, and the basic principles and structure classification of the major parts. Then it summarizes related knowledge of the wind and air dynamics for wind power generation, and analyzes the startup principle, rotational principle and aerodynamic characteristics of wind turbine as well as the basic principle of gathering wind power generation. On this basis, the thesis proposes a design proposal of the integrated power generation system with reflective-type focusing sunlight and horizontal axis gathering wind, and discusses its operational process in detail.
In addition, this thesis mainly researches the lateral spectrum splitting with a triple prism, studying its dispersion principle from the prism materials, analyzing its spectral process according to the geometrical optics theory, establishing the lateral spectrum splitting model of prism and simulating through MATLAB programming to study the spatial distribution of the splitting spectrum. Thus, it will be convenient and fast to determine the size of concentrating solar cells for the correspondin
