针对船用核动力装置的设备类型和运行特点,给出了二回路系统主要设备耗汽量计算方法。考虑二回路系统设备繁多、工况多变、耦合性强等实际特点,建立了基于多参数迭代法的热平衡计算模型。利用已知参数验证所建立热平衡模型和编制程序的计算精度。分析了3种典型工况下核动力装置特有设备的汽水流量及状态参数的匹配特性,得出了不同工况下的装置效率。相应研究成果可为船用核动力二回路系统的变工况运行研究和设计优化提供技术借鉴和参考。
According to types of equipment and operation characteristics of Marine nuclear power plant, the method of steam consumption computing of main secondary circuit equipment is given. A multi-parameter iteration heat balance computing model is established on the basis of considering practical features such as multi-equipment, multi-mode and strong coupling of secondary circuit. The known parameters are used to verify the established heat balance model and the computing precision. The steam and water flow rate and the matching feature of peculiar equipment of nuclear power plant under three typical operating conditions are analyzed, and the efficiency of power plant under different operating conditions is achieved. Through the research result of secondary circuit, technology references are provided for the study of variable operation and design optimization.
