DIGITAL MODELS OF STEADY MODES OF HEAT SUPPLY SYSTEMS BASED ON INVERSE CHARACTERISTICS

Abstract

Methods and algorithms of digital models for describing and solving the calculation of steady-state hydraulic regimes of heat supply systems, a modified nodal model for calculating the flow distribution,using the method of a new approach to forming a system of equations of nodal heads, in which not direct, but inverse characteristics of passive and active elements of the pipeline network are used. The result of the analysis of the numerical efficiency of the contour and nodal models based on the developed information-graphic system is presented.
