摘　　要：为适应小型模块化核动力装置对新型动力转换技术的选型论证和总体评估需要,本研究重点针对自由活塞斯特林动力转换技术以及工程应用中的关键问题,对比分析了百瓦级同位素-斯特林电源系统、千瓦级反应堆-斯特林电源系统和十千瓦级太阳能-斯特林电源系统的典型应用方案,给出了斯特林动力转换系统的输出功率、转换效率两个关键参数的性能估算模型。研究结果表明,斯特林动力转换效率可达到卡诺循环效率的60%左右,但输出功率一般在几十千瓦以下,需要通过多个机组模块化配置实现更大发电能力,其中耦合结构及传热过程是影响斯特林动力转换系统性能的关键因素。本研究采用的估算模型和分析结果能够为斯特林动力转换系统的性能评估和工程应用提供支撑。In order to meet the needs of small modular nuclear power plant for the type selection,demonstration and overall evaluation of new power conversion technology,this study focuses on the free piston Stirling power conversion technology and the key technical problems in engineering application,comparing and analyzing the typical application concepts of the hundred-watt isotope-Stirling power supply system,the kilowatt nuclear reactor-Stirling power supply system,and the ten-kilowatt solar power-Stirling power supply system.The performance estimation models of two key parameters,output power and conversion efficiency,of Stirling power conversion system are given.The research results show that the conversion efficiency of Stirling engine is able to reach about 60%of the Carnot cycle,while the output power is generally below tens of kilowatts.For more power generation through the modular configuration of multiple units,the coupling structure and heat transfer process will be the key factors affecting the performance of Stirling engine.The estimation model and analysis results proposed in the paper are useful to support the performance evaluation and engineering application of Stirling power conversion technology.
