The invention discloses a Brayton cycle power generation system coupled with thermoelectric power generation and an operation method, and is mainly applied to the field of novel power cycle power generation such as nuclear power and solar energy. The system comprises a high-temperature heat source, a separation valve, a thermoelectric power generation system, a storage battery, a collection three-way valve, a turbine, a heat regenerator, a cooler and a compressor. The system comprises three operation modes, the opening degree of a flow dividing valve is adjusted, the output power of two powergeneration modules is matched, so that the system operates according to three modes of thermoelectric power generation, Brayton cycle power generation and hybrid power generation under different loadrequirements, the load changing flexibility of the system is improved, and the all-working-condition self-adaptive operation is realized.
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...
