Abstract
The invention aims at providing a set of system for comprehensively increasing light radiation intensity and utilization rate of solar power station. The basic design idea of the set of system bases on the technology of increasing the photovoltaic intensity on the surface of a solar photovoltaic cell and simultaneously comprehensively utilizing solar photovoltaic for power generation and the solar thermal power generation technology. The specific method is as follows: large-scale array reflectors and a concentrating tower are increased on the basis of the traditional photovoltaic power station. At first, the computer-controlled array reflectors reflect sunlight to the concentrating tower according to the geographical coordinates of the power station, the sun position and the weather condition; and the concentrating tower radiates and reflects the light to the surface of the photovoltaic cell at an optimal angle, thus the light radiation intensity on the surface of the photovoltaic cell is enhanced and the generating capacity of the photovoltaic cell is increased. The concentrating tower can be used as a heat collection tower for solar heat energy power generation. Different coatings are coated on the reflector of the concentrating tower according to requirements, thus the radiation with longer wavelength transmits the reflector to be used as a heat source of a heat collector, and the radiation with shorter wavelength is reflected to the surface of the photovoltaic cell to be used for power generation. The set of system provided by the invention has the advantages that the cost of the array reflectors is relatively lower, the radiation intensity of the surface of the photovoltaic cell is enhanced and the generating cost is lowered.

The present invention relates to the comprehensive system that improves solar power station light radiation intensity and utilization ratio of a cover, it is characterized in that: this solar power station by photovoltaic battery array, reflecting mirror array, optically focused tower system, heat energy power-generating system, the reflector and the computer controlled system of long wave transmission and shortwave reflection are constituted.Photovoltaic battery array receives except that natural solar radiation, also receives by reflection mirror array and optically focused tower system radiation reflected.The reflector that has specific coatings is housed on the optically focused tower, and this reflector can make the short radiation of solar radiation medium wavelength reflex on the photovoltaic cell, and long wave is this reflector of transmissive then, injects the heat collector on the optically focused tower, is used for heat energy power-generating.For utilizing the solar radiation that receives to greatest extent, whole system will be by the computer control photovoltaic battery panel, the parameters such as angle of array mirror and optically focused tower reflector.Generally speaking, this system is made up of two cover electricity generating devices, and a cover is a solar photovoltaic generation system, and an other cover is the solar energy power generation system.
The work of whole system comprises the steps:
1) will with optimal angle radiation as much as possible be reflexed on the optically focused tower according to conditions such as power station geographic coordinate of living in, weather conditions, position of sun by computer-controlled reflection mirror array;
2) reflector on the optically focused tower will be used for generating according to reflexing to photovoltaic battery panel from the light of reflecting mirror array from parameters such as the light angle of reflecting mirror array, photovoltaic cell Board position, available light incident angles;
3) because the long wave in the solar radiation can see through the reflector on the optically focused tower, these radiation will be used for heating heat collector, and then promote power generating equipment such as turbo machine.
The invention has the advantages that following three aspects:
1) cost of array mirror is relatively low, and can improve the radiation intensity on photovoltaic cell surface significantly through reflection, and then improves generating efficiency; In addition, this raising effect all is effectively to any photovoltaic cell, and therefore very strong use value is arranged;
2) through the combination of array mirror and optically focused tower, photovoltaic cell surface emissivity intensity is had only humidification, and can not influence the reception of photovoltaic cell itself the natural light radiation;
3) because photovoltaic cell need be main radiation with short wavelength; And the solar energy power station need be main radiation with long wavelength; Thereby through using the reflector of band coating; Long wave part in the natural light can be absorbed by the heat collector on the optically focused tower, and shortwave then is reflected onto the photovoltaic cell surface and adds intense radiation.Thereby photovoltaic plant is combined in the solar energy power station.This plays remarkable effect to reducing cost of electricity-generating.
