Abstract

The invention provides a heliostat and photovoltaic panel combined heliostat system for tower-type photothermal power generation. The system comprises a heliostat field provided with several rows of heliostats, a heliostat control subsystem for controlling an azimuth and a horizontal angle of the heliostat, and a photovoltaic power generation subsystem for providing power for the heliostat controlsubsystem; the heliostat comprises a heliostat mirror surface main body and a heliostat support column; the photovoltaic power generation subsystem comprises a photovoltaic panel, a storage battery pack and a charging and discharging controller; the photovoltaic panel is arranged at the back of the heliostat mirror surface main body; and the photovoltaic panel at the back of the heliostat mirrorsurface main body at a front row is used for receiving sunlight reflected by the front of the heliostat mirror surface main body at a rear row sheltered by the back of the heliostat mirror surface main body at the front row. The system provided by the invention can effectively reduce sheltering efficiency loss of the heliostat field, improve power generation efficiency of a photothermal power generation station and effectively reduce power generation cost.

Description

technical field [0001] The invention relates to the technical field of solar power generation, in particular to a heliostat system combined with a heliostat and a photovoltaic panel for tower photothermal power generation. Background technique [0002] Electric energy is an important guarantee for social development and economic construction. Its close combination with high technology has created a rich and colorful human life. At the same time, the wide application of electric energy has also led to frequent shortages of electricity supply worldwide. From a global perspective, thermal power generation is currently the most important form of power generation. However, due to the massive combustion of fossil fuels such as oil, natural gas, and coal, it not only brings about the problem of energy depletion, but also causes environmental pollution, especially air pollution. serious. Since the beginning of 2013, the term PM2.5 has attracted people's attention, and severe smog h...
