Solar energy is a renewable resource without pollution and zero emission, and the development and utilization of the solar energy become important components of the energy strategy of the current society. The solar power generation mode mainly comprises solar photovoltaic power generation and photo-thermal power generation. The principle of photovoltaic power generation is to directly convert solar radiation energy into electric energy by using a battery plate, and the photovoltaic power generation has the advantages of simple equipment and mature technology and is widely applied to the commercial field. The solar photo-thermal power generation technology utilizes a heliostat to gather solar energy to the surface of a heat collector, and a working medium absorbs heat energy to generate steam to drive a turbine set to generate power. For the photovoltaic power generation technology, the energy consumption in the process of manufacturing the cell panel is high, the environment is polluted, the output voltage is low, and the photovoltaic power generation system is suitable for a distributed energy system. Different from a photovoltaic power generation technology, the photo-thermal power generation technology is clean and pollution-free, high in power generation power and stable in output power, but has the defects of long construction period, complex operation and maintenance and the like. One of the biggest problems faced by solar power generation technology is that it has intermittency, and wind power generation, hydroelectric power generation and the like also face the challenge of unstable power output. Different from the renewable energy power generation mode, the photo-thermal power generation can realize continuous power generation at night and in rainy days by utilizing a heat storage technology, and the stability of power output is kept. In addition, compared with other power generation modes, the photo-thermal power generation technology has incomparable advantages that the problems of high energy consumption, high pollution and the like basically do not occur in the equipment production process. Therefore, solar photo-thermal power generation is regarded as the most promising renewable energy power generation mode, and has become a hot spot for research and application in the clean energy field of various countries.
At present, the photo-thermal power generation technology applied in engineering practice is divided into four types, namely a groove type solar power generation system, a linear Fresnel type power generation system, a tower type solar power generation system and a disc type solar power generation system. The solar energy heat collecting system is divided into a line focusing heat collecting system and a point focusing heat collecting system according to different light condensing modes of a condenser. The first two power generation systems belong to a line focusing heat collection system; the latter two power generation systems belong to point-focus heat collection systems. In recent years, the development of the photo-thermal power generation technology has been rapidly advanced. The development of solar energy resources in the united states and spain is relatively early, leading globally in terms of technical and commercial applications. With the increasing awareness of global climate change, other countries with abundant solar energy resources are also promoting the technology of solar-thermal power generation, and they have come out one after another.
A reward policy aims at constructing more photo-thermal power stations. At present, new investment and construction heat tide has been raised in all countries in the world, the economical efficiency of renewable energy sources is more prominent, and the market competitiveness is greatly improved. With the addition of more and more countries to the renewable energy market, the global photo-thermal power generation total installation scale continuously rises, the photo-thermal installation scale announced and constructed by various countries is explosively increased, and the solar photo-thermal power generation industry presents a flourishing scene of vigorous development. At present, tower and trough thermal power generation technologies dominate the world in view of the number of photothermal power stations operated, built and planned throughout the world.
