In order to obtain the optimum design parameters of the supercritical carbon dioxide power system,this paper establishes a thermal analysis model of system and main equipment.pa-rameter performance analysis and multi-objective optimization design of the supercritical carbon dioxide power generation device system with a heat pipe reactor is carried out.We develop an op-timal solution set of power generation device system parameters with an output power of 1 MW(e),and conduct system sensitivity analysis.The research results indicate that increasing system param-eters can achieve the goal of improving system cycle efficiency,but it also increases the size and scale of the equipment,which is unfavorable for improving compactness.The sensitivity of various main thermal parameters to system efficiency and volume varies greatly.The final optimization solution can be selected from the optimum solutions set in this article,based on the size of the available space,in order to obtain the optimum design parameters with better efficiency and compactness.
