摘要
Abstract
Based on the graph theory-based topology model and the hydraulic-thermal characteristics model of the heating network,the optimization model for valve opening was established,with the goal of minimizing the absolute value of the difference between the actual hydraulic imbalance and the ideal hydraulic imbalance in the primary pipe network.Addressing the high-dimensional optimization challenge posed by the excessive number of valves in the large-scale central-ized heating systems,the front valve of the heating sta-tion with common regulation and the branch line valve with significant effect were selected as the optimization objects,leveraging the topology to facilitate dimension-ality reduction of optimization variables.Taking the pri-mary pipe network of a large-scale central heating sys-tem in Xi'an as an example,the optimization effect of the optimization model was evaluated and analyzed.Af-ter optimization,the hydraulic imbalance and thermal imbalance of the heating system are significantly im-proved,and the hydraulic conditions of the proximal,middle and remote heating stations of the pipe network are improved.关键词
