400 MW Low Temperature Heating Reactor Power Regulation System Simulation Research

  • 摘要: 随着日益增长的居民供暖需求,以及对环保的重视,核能供热以其显著减排、供热量大、安全性高的优点,对保护环境、减少污染、缓解燃煤需求等具有积极意义。通过以400 MW低温供热堆一回路中间热交换器为仿真边界,依回路建立各部件的数学模型,基于Matlab/Simulink软件平台建立上述模型的仿真模型。通过设置功率阶跃适应负荷变化,研究低温供热堆控制系统调节能力及一回路负荷跟踪能力。仿真结果表明:低温供热堆一回路功率调节系统跟随负荷变化调节性能良好,控制系统对反应性扰动的响应良好,对于以后设计低温供热堆的运行方式,可考虑负荷运行。

     

    Abstract: As increasing heating needs of residents and more attention on environmental protection, nuclear heating advantages of reduction coal emission, large heating supply, and high safety have positive influence on protecting environment, reducing pollution and relieving coal demand. By using the 400 MW low temperature heating reactor primary loop IHX as the simulation boundary, mathematical model of each component was established and simulation model of above mathematical model was established based on the Matlab/Simulink platform. By setting step power as load change, the control capacity of the control system and load tracking ability of the primary loop system were studied. The simulation results show that primary loop system has good load tracking capability, and the control system responds reactive disturbance well. For future operation mode of low temperature heating reactor load following can be considered.
