供热管网水力平衡调节方法研究
Study on hydraulic balance regulation method of heating networks
摘要：
水力失调是供热系统能耗大的主要原因，在实际工程中很难解决。本文采用邻近调节法，搭建了一种基于图论理论的二次供热管网水力调节模型，依此评估和比较不同的调节方法。结果表明：邻近调节法从水力失调度最差的用户开始按邻近顺序进行依次调节，调节效果好、调节次数少，有利于精准控制，可用于二次管网初调节和运行过程调节。本文研究成果可以为现场调试和控制提供指导。
Abstract：
Hydraulic imbalance is the main reason for the high energy consumption of the heating system, and it is difficult to solve in practical engineering. In this paper, a hydraulic regulation model of the secondary heating network based on graph theory is established by using the proximity regulation method, and different regulation methods are evaluated and compared by using this model. The results show that the proximity regulation method starts from the worst hydraulic regulation degree users to adjust in the adjacent order, which has a good regulation effect and fewer regulation times, is conducive to accurate control, and can be used for the initial regulation of the secondary pipe network and the regulation of the operation process. The research results of this paper can provide guidance for on-site commissioning and control.
