摘　　要：为获得超临界二氧化碳动力系统最优设计参数,本文建立了热力分析模型和主要设备模型,开展热管式反应堆为热源、简单回热架构的超临界二氧化碳发电装置系统参数性能分析和多目标参数优化设计。形成1 MW(e)输出功率的发电装置系统参数最优解集,并开展系统敏感性分析。研究结果表明提升系统参数可达到提升系统循环效率的目的,但同时也增加了设备尺寸规模,对提升紧凑性不利,各主要热力参数对系统效率和体积的敏感性相差较大。最终优化解的选择可从本文最优解集中,按可布置空间大小选取,从而获得兼顾效率和紧凑性的最优设计参数。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.parameter 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 optimal 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 parameters 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.
