Abstract

The invention discloses a Brayton cycle power generation system coupled with temperature difference power generation and an operation method thereof, which are mainly used in new power cycle power generation fields such as nuclear power and solar energy. The system includes high-temperature heat source, separation valve, thermoelectric power generation system, storage battery, converging three-way valve, turbine, regenerator, cooler and compressor. The system of the present invention includes three operation modes. By adjusting the opening of the diverter valve and matching the output power of the two power generation modules, the system can operate in three modes of temperature difference power generation, Brayton cycle power generation and hybrid power generation under different load requirements, improving the The variable load flexibility of the system realizes self-adaptive operation in all working conditions.

Description

technical field [0001] The invention relates to a Brayton cycle system, in particular to a Brayton cycle power generation system coupled with temperature difference power generation and an operation method. Background technique [0002] Compared with the traditional steam Rankine cycle, the Brayton cycle system has the advantages of high cycle efficiency and compact system structure, and is widely used in coal-fired power generation, nuclear power and solar thermal power generation. The working fluid is boosted by the compressor, heated by a high-temperature heat source, worked by the turbine expansion, and released by the regenerator and cooler at constant pressure, completing a Brayton cycle to convert the heat energy contained in the high-temperature working fluid into mechanical energy. However, during the low-load operation of the cycle system, since the actual flow rate is much smaller than the design flow rate of the system, the compressor and turbine deviate from the...
