A performance test platform suitable for the core equipment of supercritical carbon dioxide Brayton cycle power generation system

Abstract

The invention relates to a performance test platform suitable for core equipment of a supercritical carbon dioxide Brayton cycle power generation system. The platform comprises a supercritical carbondioxide Brayton cycle power generation device test cycle loop and an auxiliary compressed air and control system which are communicated with each other; in the test circulation loop, a carbon dioxidegas cylinder, a pneumatic booster pump and a high-low temperature test box are sequentially connected; the high-low temperature test box is connected with a gas inlet of a compressor; the compressor,a heat exchanger, a turbine and a first cooler are sequentially connected; a gas outlet of the first cooler is finally connected with a gas inlet of the compressor, and the turbine is coaxially connected with a permanent magnet synchronous motor. The auxiliary compressed air and control system adjusts compressed air to make the compressed air accord with the exhaust pressure, flow and temperatureof the marine main engine, and finally the compressed air is conveyed to the heat exchanger of the test circulation loop. According to the invention, the purpose of testing the overall efficiency of the supercritical carbon dioxide Brayton cycle power generation system is realized, and the purpose of testing the performance of a core equipment compressor and a heat exchanger is also realized.

Description

Technical field [0001] The present invention relates to the field of power generation technology, particularly, to a suitable supercritical carbon dioxide Brayton cycle power generation system apparatus performance test core internet.
