摘　　要：基于系统仿真软件Flowmaster,建立了模块式小型堆主给水系统的仿真模型。系统模型包括蒸汽发生器、给水泵、主给水调节阀、旁路给水调节阀以及相关管道。通过分析系统稳态运行特性,验证了模型的准确性。然后对比分析了升功率过程中主给水调节阀开度变化与主给水调节阀开度不变两种方式,主给水系统的流量特性、阀门的开度特性以及阀门压降特性等关键参数,可为主给水系统运行以及给水调节阀的选型提供参考。Based on the system simulation software Flowmaster,the simulation model of the modular small reactor main feed water system is established.The system model includes steam generator,feed water pump,main feed water control valve,bypass feed water control valve,and related pipelines.The accuracy of the model is verified by analyzing the steady-state operating characteristics of the system.Then,the comparative analysis is conducted between two ways in which the opening of the main feedwater control valve changes and stays the same during the power.The key parameters of the main feed water system,such as flow characteristics,valve opening characteristics,and valve pressure drop characteristics are analyzed,which can provide reference for the operation of the main feed water system and the selection of feed water control valves.
