摘　　要：多热源联网供热能够有效提高整个供热系统的可靠性和经济性。原大庆油田矿区服务事业部通过对让龙集中供热系统各个热源和热网进行规划整合为统一的供热系统,建立并实施科学有效的联网运行方案,将供热运行调节分为初末期、中期、高峰期三个时期。初期运行首先启动宏伟热源,作为基础热源;中期作为供暖期的主要运行时段启动宏伟电厂和华能电厂2个热源运行;高峰期时宏伟热源和华能热源供热负荷达到上限,启动登峰燃煤锅炉房,实现宏伟电厂、华能电厂和登封燃煤锅炉房三热源联网运行,充分发挥电厂热电联产优势,最大限度减少能源消耗,在满足系统总体负荷的前提下,达到降本减碳的供热目的。The multi-heat source network heating can effectively improve the reliability and economy of the whole heating system. What’s more, by planning a unified heating system for each heat source and heating network of the Ranglong central heating system, the original Daqing oilfield mining service business has established a scientific heating operation scheme and divided into three periods : the early and late period, the middle period, and the peak period.First of all,in the initial operation, the Hongwei heat source starts as the basic heat source.And then two heat sources of Hongwei and Huaneng are main operation of medium heating period. Most importantly,during the peak period, if the heating load of Hongwei heat source and Huaneng heat source reaches the upper limit, start the peak coal-fired boiler room,which can realize the network operation of Hongwei power plant, Huaneng power plant and Dengfeng coal-fired boiler room, give full play to the advantages of cogeneration in power plant and minimize energy consumption. On the premise of meeting the overall load of the system, the heating purpose of cost reduction and carbon reduction can be achieved.
