基于可靠性的环型热网模式的研究

Study on Reliability-based Design of Ring-shaped Heat Supply Network

本文分析了具有分级结构的环型热网的优点,提出了构建高可靠性环型热网的要素,论述了热网分级设置的部署、输送备用的依据、各支干线规模的限定、限额供热指标及阀门的优化设置等问题,并用算例论证了高可靠性环型热网的模式。

In this paper, the advantages of hierarchical structure of ring-shaped heat supply network were analyzed, and the design factors of configuring high reliability ring-shaped network were presented. Furthermore, other issues were discussed, including the scheme of hierarchy, the basic principle of spare transportation, the restrictions of each heat-supply unit scale, the limited heat supply index and the optimize design of valves. At last, an example was given out to verify the mode of high reliability ring-shaped heat supply network.
