摘要
针对太原市集中供热热网统一调度系统后发现的新问题,结合热源供热能力、管网系统、负荷供需平衡分析、承压、快速隔离等多方因素,对多热源联网运行深度分析,改变原12大热网的运行模式为6大热网,并对多热源联网运行区域分析。太古、城西联网从理论和试验方面同时验证了超大型热网联网运行的可行性及稳定性,推动南部热网、二电热网、瑞光热网的深度联网,并从理论分析上验证了多热源深度联网运行对热网水力工况的改善。多热源深度联网,充分发挥现状管网的互联互通,提升了基础热源的供热能力,供热成本降低了17%,实现了全网经济安全运行。
In light of the new problems found after the unified scheduling system of centralized heat supply heating network in Taiyuan City,taking multiple factors into consideration,such as heat supply capacity of heat sources,pipe network system,load supply and demand balance analysis,pressure-bearing,rapid isolation,etc.,the paper analyzes the operation depth of multi-heat source network in Taiyuan City,changes the operation mode from the original 12 large heat networks to 6 large heat networks,and analyzes the operation area of the multi-heat source network.Taiyuan-Gujiao and western Taiyuan City area networks have simultaneously verified the feasibility and stability of super-large heat networks operation from theoretical and experimental aspects,and thus promotes the deep networking of Southern Heat Network,2nd Power Heat Network and Ruiguang Heat Network,and then theoretically proved the improving role of multiple heat source depth networking upon hydraulic conditions of the heat network.The deep networking of multiple heat source gives full play to the interconnection of the current pipeline network,improves the heating capacity of the basic heat sources,reduces the heating cost by 17%,and achieves economic and safe operation of the entire network.
