摘要(Abstract)：

为研究蒸汽系统的热惯性从而解决工业园区低碳能源系统调度难题，提出了反映蒸汽时空传输特性的蒸汽系统动态分析模型，建立包括5个存储关键参数和3个指标的蒸汽储能虚拟模型，用于量化热惯量。对163节点城市规模蒸汽系统运行过程中的热惯量进行了量化，其中该蒸汽网络在0.5 h调度周期下的净储热量可达7 440.3 kg，放能能力达到了10.16 t，平均放能利用率达到了14.59%，为工业园区蒸汽系统分析和运行优化提供了定量依据。
In order to investigate the thermal inertia of steam systems and address the scheduling challenges of lowcarbon energy systems in industrial parks, a dynamic analysis model reflecting the spatiotemporal transmission of steam is proposed. A virtual steam pipe energy storage model is established, incorporating 5 key storage parameters and 3 indicators to quantify thermal inertia. The thermal inertia of a 163-node urban-scale steam system during operation is quantified, revealing a net stored heat of 7,440.3 kilograms and a discharge capacity of 10.16 tons within a 0.5-hour scheduling cycle, and an average discharge utilization rate of 14.59%. This paper provides quantitative basis for the analysis and optimization of steam systems in industrial parks.
