Abstract

The invention belongs to the technical field of solar energy application, and specifically relates to a solar energy power and heat cogeneration system. Since solar energy is intermittent unstable energy, when the solar energy satisfies electricity demands in a power supply mode, assistance of electric power storage is needed. Aimed at characteristics that heat application and heat storage are little influenced by intermittent power supply, the invention provides a solar energy power and heat cogeneration system. Using a power generation portion of heat supply in a power and heat cogeneration method, electricity can be regulated to a power supply portion of electricity utilization in an off-peak period, making power supply more stable, and meanwhile burden of storage batteries is eased and life of the storage batteries is prolonged. A technical scheme of directly supplying heat and storing heat on the premise that power requirement is ensured is used, and a problem of solar energy storage is solved by low investment. Under common environment conditions, converting light to electricity provides more applications and ways for people and is more convenient. Compared with an optothermal and heat-electricity method of heat and power cogeneration, the light-electricity and electricity-heat method is advantaged by simple and flexible, and the method is easy to realize, so solar energy power and heat cogeneration is more suitable for requirements of ordinary people than heat and power cogeneration.

Description

technical field [0001] The invention belongs to the technical field of solar energy application, and relates to a combined solar power heating system. Background technique [0002] The application of distributed energy is becoming more and more popular, especially the application of new energy such as solar energy, which is supported by governments of various countries and favored by people. In new energy applications such as solar energy, combined heat and power is an existing solar-thermal-electric energy supply scheme. Its technical feature is to gather sunlight to heat the liquid to the evaporation temperature, drive the steam generator to generate electricity, and the waste heat can be used as a heat source to realize combined heat and power supply. Such a system needs to have a certain scale. Although the utilization rate of solar energy has been improved, within a certain scale, secondary energy distribution and transmission are required, which increases investment a...
