Heat supply pipe network equivalent region identification method based on visual mode

Abstract

The invention discloses a heat supply pipe network equivalent region identification method based on a visual mode, and relates to the technical field of reliability analysis of a heat supply pipe network. The invention aims to solve the problem that an existing heat supply pipe network is complex in structure and huge in scale, so that in practice, reliability analysis difficulty is high and feasibility is low. The heat supply pipe network equivalent region identification method has the technical key points of redrawing of all components of the heat supply pipe network, information input of the heat supply pipe network, filling of component data of the heat supply pipe network and parameter setting; the specific process of identification of an equivalent region of the heat supply pipe network comprises steps of equivalent region data filling and equivalent region partitioning; the equivalent region partitioning sequentially comprises: traversing the heat supply pipe network, merging pipe sections, marking flow directions of the pipe sections, distinguishing one-way pipe sections and bidirectional pipe sections, distinguishing one-way valves and bidirectional valves and merging the equivalent region. According to the heat supply pipe network equivalent region identification method disclosed by the invention, accuracy and efficiency of related calculation analysis of the heat supply pipe network are improved, and moreover, the graphic-based calculation analysis process is more visual. Use of the method disclosed by the invention improves reliability analysis efficiency of the existing heat supply pipe network.

Description

technical field [0001] The invention relates to a method for identifying an equivalent area of ​​a heating pipe network, and relates to the technical field of reliability analysis of a heating pipe network. Background technique [0002] With the rapid development of my country's economy, infrastructure construction is ushering in a new climax, and people's pursuit of improving the quality of life has led to the continuous expansion of the scale of the central heating pipe network and the increasingly complex structure of the pipe network, which has also led to a decrease in the heating accident rate. Therefore, the research on the reliability of the heating pipe network is of great significance. The research on the reliability of the heating pipe network has been studied for many years at home and abroad, and there are relatively mature research theories. However, with the increase of the scale of the pipe network, the aging of the existing pipe network and the transformatio...
