【摘要】 为解决传统压水堆核电机组难以在未来参与电网调峰的问题，提出了一种耦合太阳能和核能的光-核-储综合能源系统，利用热力系统仿真软件EBSILON搭建了系统模型，研究了设计工况下系统的热力学性能并进行了系统在不同运行策略下的?分析。不同运行策略下的?分析研究表明，系统中?损最大的3个设备依次为蒸汽发生器、集热场和汽轮机高压缸第一级，三者?损之和接近总?损的50%。与此同时，集热场的?效率主要受设计法向太阳直接辐射量变化影响，在不同运行策略下的最大变化量为2%，电加热器的?效率基本不变。更多还原

【Abstract】 To solve the problem that traditional PWR nuclear power units cannot meet the need to participate in grid peak regulation in the future, an Solar-Nuclear-Storage Hybrid System that couples solar energy and nuclear energy was put forward. A system model was built with thermal system simulation software EBSILON, where exergy analysis of the system under different operation strategies was carried out to study the thermodynamic performance of the system under design conditions. The exergy analysis and research under different operation strategies show that the three equipment with the highest exergy losses in the system are steam generator, solar field and steam turbine high pressure cylinder first stage, and the exergy loss of the three equipment in total is close to 50% of the total exergy loss. At the same time, the exergic efficiency of solar field is mainly affected by the change of direct normal irradiance. The exergic efficiency of electric heater is basically unchanged with the maximum change of 2% under different operation strategies.更多还原
