摘　　要：以某车站综合体作为研究对象,预测冷热电负荷,对以热定电、以电定热方式下的天然气冷热电联供系统的设备配置及系统流程进行分析。采用DEST模拟软件模拟车站综合体全年逐时冷热负荷。在估算电负荷时,考虑不同功能房间照明装置、用电设备的电负荷指标以及空调系统设备(空调末端装置、循环泵、冷却塔)的电负荷指标,根据相关用电装置逐时使用率对电负荷进行估算。在以热定电、以电定热方式下,天然气冷热电联供系统的设备配置及系统流程均存在差别。A station complex is used as the research object to forecast the cooling,heating and power loads,and the equipment configuration and system flow of the natural gas combined cooling,heating and power system under the modes of the power determined by heat and the heat determined by power are analyzed.The DEST simulation software is used to simulate the hourly cooling and heating loads of the station complex throughout the year. When estimating the electrical load,the electrical load indicators of the lighting devices and the electrical equipment in different function rooms and the electric load indicators of the air-conditioning system equipment（ air-conditioning terminal device,circulating pump and cooling tower） are considered,and the electrical load is estimated according to the hourly utilization rate of the related electrical equipment. There are differences in the equipment configuration and system flow of the natural gas combined cooling,heating and power system under the modes of the power determined by heat and the heat determined by power.
