Study On Heating Network Reliability Based On The Equivalent District

This thesis is mainly based on the equivalent area of heating pipe network reliability analysis, and the heating pipe network reliability analysis is based on the previous theoretical studies. The main contents include: research of the equivalent area size and uniformity of the heating pipe network for reliability, heating pipe network division based on equivalent area and reliability analysis of computer-aided design, verification of the correctness of the aided design program based on actual heating pipe network analysis to verify the correctness of theoretical analysis conclusions.Through the research of simplified equivalent areas of practical heating pipe network, the influence of equivalent area size and uniformity to the reliability of heating pipe net work is studied, which is the influence of the research method to the research result. The branch type heating network and ring type heating network are studied respectively, and the results are compared to draw the conclusion.The program is based on the secondary development of Auto CAD, and visualized the heating pipe network data, to achieve the equivalent area of the heating pipe network zone and complete the calculation of heating pipe network reliability index based on the equivalent area. Heating pipe network is connected with the database, so that heat supply network graphics correspond with the database. Thus we can either update the database through the network graphic operation, or by calling the data in the database of network diagrams for calculation and analysis, to achieve a unified graphics operations and data analysis. The visualization program has an open architecture that can improve and expand its capabilities in the design on the basis of this thesis, and is the foundation for the followup program development on the heating network reliability analysis.The last chapter analyzes the practical examples to verify the correctness and practicality of the aided design program, and verified the effect of the size and uniformity of the proposed equivalent area on heating pipe network reliability.
