摘要
目的:“燕龙”池式低温供热堆是一种专门用于供热的核能系统,它运行在敞口的低温低压条件下,其运行控制具有特殊性,为保证供热品质,需寻求一种能够匹配热网负荷的反应堆运行控制模式。方法:本文基于Matlab/Simulink仿真平台,建立了反应堆各传热系统以及热网模型,提出了一种负荷跟踪的供热控制模式并进行仿真研究。结果:仿真结果表明,该模式能够跟踪热网负荷的变化来控制反应堆功率,还能够根据热力公司的调度值,使反应堆的供水出口温度跟踪调度值的变化。同时,能够将用户室内温度控制在16.94~19.79℃的范围之间,用户采暖体验良好。而且在经济节能的层面上,该模式相较传统基荷运行的供热模式具有一定的优势。结论:因此,本文所提出的控制方法能够满足热网对供热品质的要求,并为燕龙的供热控制系统设计提供了一定的参考。
Yanlong reactor is a special low-temperature heating system,which operates under low temperature and atmospheric pressure and its operation control has particularity.In order to ensure the heating quality,its necessary to find a reactor operation control mode which match the heat load.Based on Matlab/Simulink simulation platform,this paper establishes the heat transfer system of the reactor and the heat network model,puts forward a load-tracking heating control mode,and carries out simulation researchs.The simulation results show that the mode can control the reactor power to track changes of the heat load,and make the water supply outlet temperature track changes of dispatching values which depend by thermal power company.Meantime,the user’s indoor temperature can be controlled between 19.79℃and 19.79℃which is suitable for daily living.Moreover,in terms of economy and energy saving,this mode has certain advantages compared with the traditional base-load heating mode.Therefore,the control method proposed in this paper can meet the demand of heating quality of the reactor,and provide a certain reference for the design of Yanlong s heating control system.
