Research on SFR Intermediate Loop Modeling, Simulation and Flow Control

  • 摘要: 针对钠冷快堆中间回路泵、管道、换热器等,采用Matlab/Simulink软件建立了一种仿真模型,对回路的流量和管道换热进行了计算。根据相似理论、泵水力特性曲线及回路压力损失等计算流量。编制了SFAC V1.0程序,该程序的计算结果与实验值符合较好,最大相对误差为5%。将管道划分为不同节段,在各节段上建立能量守恒微分方程组,从而建立了管道换热计算的模型。同时,对钠流量的控制方式进行了设计和改进,对控制参数进行了整定,并对流量需求进行了计算。计算结果表明,该控制方式的控制品质较高。

     

    Abstract: In this paper, a simulation model composed of sodium flow calculation model and thermal analysis model was developed for sodium-cooled fast reactor intermediate loop flow and thermal analysis using Matlab/Simulink software. Sodium flow calculation model was based on similarity theory, hydraulic performance characteristic of pump and pressure drop of intermediate loop, and SFAC V1.0 was programmed. The sodium flow calculated by this code is in good agreement with the experimental data, and the maximum relative error is about 5%. The pipeline was divided into several segments and differential equations for energy conversation on each segment were established, resulting in a heat transfer calculation model for pipeline. The sodium flow control was also studied in this research, and control parameters were set by tuning methodology. The flow regulation was simulated to evaluate this strategy, and the control quality of this strategy is rather high.
