摘要
核电站主给水流量控制系统的主要功能是向蒸汽发生器供应给水并且调节给水流量以将蒸汽发生器二次侧的水位维持在一个随汽轮机负荷变化所预定的基准值上。为了提升主给水流量控制系统的安全性及可靠性,在华龙一号设计中增加宽量程流量测点,优化主给水流量选择模块设计,提升给水流量信号容错水平,降低给水流量测量故障概率。
The main function of the nuclear power plant's main feedwater flow control system is to supply water to the steam generator and adjust the feedwater flow to maintain the water level on the secondary side of the steam generator at a predetermined reference value as the load of the steam turbine changes.In order to improve the safety and reliability of the main feedwater flow control system,a wide-range flow measurement point was added to the Hualong No.1 design,the design of the main feedwater flow selection module was optimized,the fault tolerance level of the feedwater flow signal was improved,and the failure probability of the feedwater flow measurement was reduced.
