Solar air turbine power generation system with heat storage function and control method thereof

Abstract

The invention discloses a solar air turbine power generation system with a heat storage function and a control method thereof. A heat collector, a heat conducting medium air heat exchanger and an overflow tank are connected into a first heat conducting medium circuit. The heat collector, a heat conducting medium molten salt heat exchanger and the overflow tank are connected into a second heat conducting medium circuit. The heat conducting medium air heat exchanger and the heat conducting medium molten salt heat exchanger are connected into a third heat conducting medium circuit. An air inlet of the heat conducting medium air heat exchanger is connected with a compressed air pipeline. An air outlet of the heat conducting medium air heat exchanger is connected with an air inlet of an air turbine. The air turbine drives an electric generator to generate electric power. A hot salt tank and a cold salt tank are connected with two heat storage salt connectors of the heat conducting medium molten salt heat exchanger correspondingly. Through the system, the water resource consumption is greatly reduced, and the system is quite simple and reliable and is of great importance in promoting photothermal technology development.

Description

Technical field [0001] The invention relates to the field of power generation technology, in particular to a solar power generation system with heat storage function and a control method thereof. Background technique [0002] With the development of social economy, environmental pollution has become an unavoidable problem and even poses a huge threat to people's health. Therefore, it is urgent to control environmental pollution, and the use of renewable energy to replace conventional fossil energy has become an important development direction. [0003] The emerging CSP technology is an important way to utilize renewable energy solar energy. The existing relatively mature photothermal technology usually converts solar energy into heat energy of the heat storage medium, and then couples the heat storage medium with the traditional steam turbine power generation system through heat exchange equipment, and then drives the heat through the heat exchange between the heat storage medium ...
