摘要: 目的 为了解决铁路站区供热系统供热量与各功能建筑需求热量不平衡而导致的能源严重浪费问题，方法 提出铁路站区供热系统热源侧与建筑物联动调节的时空差异化运行策略，以响应站区内各建筑室内温度变化需求。首先，分析常规热源侧和建筑物侧运行调节策略，在此基础上研究时空差异化运行策略；其次，以大同某铁路站区供热系统为例，利用Simulink建立供热系统仿真模型；最后，在验证模型有较高准确性的基础上，对比分析3种不同运行策略下系统室内温度动态响应和能耗。结果 与热源气候补偿质调节和建筑量调节运行策略相比，热源侧与建筑物联动调节的时空差异化运行策略不仅实现了不同建筑分时分温供热的需求，还有效减小了正常供热时间段和低温供热时间段室内温度波动幅度，提高了室内热舒适性。同时与系统无运行调节相比，热源质调节运行策略节能率为20.7%，建筑物量调节运行策略节能率仅为17.5%，时空差异化运行策略节能率达38.5%。结论 本文提出的热源侧与建筑物联动调节的时空差异化运行策略能够满足铁路站区内不同功能建筑的室内变温需求，减小室内温度波动幅度，具有良好的节能效果。

Abstract: Objectives In order to solve the problem of serious energy waste caused by the imbalance between the heat supply of the heating system in the railway station area and the heat demand of each functional building， Methods the time-space differentiation operation strategy of linkage adjustment of the heating source side of the railway station heating system and the building was proposed，in response to the demand of indoor temperature changes in each building area.First，the operation regulatory strategy of conventional heating source side and the building side were analyzed，and the time-space  differentiation operation strategy was studied on this basis；then，taking the heating system of a railway station area in Datong as an example，the heating system simulation model was established by Simulink；Finally，on the basis of verifying the high accuracy of the model，the system’s indoor temperature dynamic response and energy consumption of the system under three different operation strategies were compared and analyzed. Results Compared with the operation strategy of compensation quality adjustment of the heat source climate and the construction volume adjustment，the time-space differentiation operation strategy of the heating source side and the building linkage adjustment not only  realized the demand of different buildings for time-sharing and temperature-sharing heating，but also effectively reduced the indoor temperature fluctuation range during normal heating period and low-temperature heating period，and improved indoor comfort.At the same time，compared with the system without operation adjustment，the energy saving rate of the heating source quality regulation operation strategy was 20.7%，the energy saving rate of the building quantity regulation operation strategy was only 17.5%，and the energy saving rate of the time-space differentiation operation strategy was 38.5%. Conclusions The space-time differential operation strategy of heating source side and building linkage adjustment proposed in this paper can meet the indoor temperature demand of different functional buildings in railway station area，reduce the fluctuation range of indoor temperature，and have good energy saving effect.
