Abstract

The invention discloses an automatic focus tracking type solar concentrating photovoltaic power generation system, and belongs to the field of concentrating photovoltaics (CPV). The problems of accuracy, cooling and weather resistance bottlenecks of the conventional CPV are mainly solved, and power generation cost is lowered. The system consists of five systems: (A), for concentrating power generation, condensing mirrors are fixed, and solar cells are driven by a stepper motor to track sunlight converging focuses; (B), for control tracking, computer time is corrected by a timing system, the position of a sunlight converging focus at another coming moment is calculated according to the original positions, module parameters, directions and positions of two sunlight converging focuses, which are manually measured at a certain time interval, and an instruction is transmitted to the stepper motor to drive the solar cells to move to the position at the moment; (C), for cooling and heat production, the solar cells are directly impregnated by a circulating liquid heat conducting medium; (D), for charging and discharging inversion, running power is stored at first, and redundant power is transmitted to a power grid; and (E), for automatic cleaning, an automatic spraying and rain wiping mode is adopted.

Description

technical field [0001] The invention relates to a concentrating photovoltaic power generation system, which belongs to the application of concentrating solar energy and the field of concentrating photovoltaics, that is, the field of Concentrating photovoltaics or CPV. Background technique [0002] Concentrating photovoltaic refers to the technology that directly converts concentrated sunlight into electrical energy through photovoltaic cells with high conversion efficiency. CPV is the most typical representative of concentrated solar power generation technology. [0003] The photoelectric conversion of crystalline silicon cells and thin film cells is the first and second generation solar energy utilization technologies, both of which have been widely used. It is considered to be the third generation technology of the future development trend of solar power generation. [0004] Concentrating photovoltaics is considered to be the third generation of photovoltaic technology is...
