MATHEMATICAL AND COMPUTER MODEL OF HEATING NETWORK BASED ON THE ELECTRONIC-HYDRAULIC ANALOGY

Abstract

This article presents the results of development of mathematical and computer model of heating network for the city of Samara. The heating network includes three heat sources: Samara State Regional Power Plant, «Centralnaya» and «Privokzalnaya» heating boilers. The model development is based on the electronic – hydraulic analogy. In particular, Kirchhoff's laws were used. In order to approximate the model to the real network, the method of automatic identification of the model was applied. Depending on the number of points with known experimental data, the accuracy of identification was 3 - 5%. The research allowed developing plans for an optimal reconstruction of heating network. The obtained results can be used for designing heating systems of big cities, heating systems and circulating systems of thermal power plants, as well as for any other multi – ring branched pipeline systems.
