Abstract

The invention provides a heat supply pipe network hydraulic calculation method based on a big data analysis technology, and the method comprises the following steps: 1, building a heat supply pipe network system topology; 2, building a digital twinning relation: 201, building a pipeline characteristic equation, 202, building a transmission and distribution analysis model, 203, building a regulation and control equipment characteristic model, 204, establishing a hydraulic joint debugging model based on big data: simultaneously establishing a topological relation, a transmission and distributionanalysis model and a regulation and control equipment characteristic model in the topological graph of the heat supply pipe network system, setting an operation boundary condition and a big data analysis mode, and establishing a hydraulic joint debugging model; 3, performing operation simulation based on a digital twinning relationship; 4, performing data iterative analysis. According to the method, a passive adjustment mode of a traditional urban heat supply pipe network system is converted into active adjustment, a favorable basis is provided, the hydraulic working condition stability of the system is improved, and the operation efficiency is improved.

Description

Technical field [0001] The present invention belongs to the field of urban heating, and involves a heating pipe network, and more particularly to a hydraulic calculation method based on high data analysis techniques. Background technique [0002] With the acceleration of urbanization in my country and the continuous improvement of people's living standards, my country's city centralized heating cause has been greatly developed. However, due to the centralized heat transfer pipe network system is a very complex multivariable control system, it has the characteristics of high heating area, more influential factors, strong internal relevance, long lag, and serious linearity, everyday operations must be guaranteed The hydraulic balance of the heat pipe network system, but also guarantees its thermal balance, therefore leads to a large operation, and the operating conditions are unreasonable. [0003] To achieve the reasonable stability operation of the heat pipeline system of the hea...
