The analysis of the directions of centralized heat supply systems (HSS) development in Russia and in a number of countries of northern Europe is made. Types of HSS operation conditions are classified, as well as goals and tasks of their calculation at different stages of control. Adaptation of the mathematical model for the solution of the adjustment calculation problem and thermal-hydraulic conditions analysis and the features of its implementation are proposed. The functions and properties of the developed information and computing complex "ANGARA-HS" are described and its differences from analogues are analyzed. The questions of the relevance of the construction of multi-level computer models of hierarchical structure HSS for the problems of calculating conditions are examined. Possibilities of graphical analysis of a priori information and calculation results by means of the developed tool are explored. Automation of control, increase of reliability, economy and quality of HSS operation require the introduction of modern mathematical modeling methods and information technologies. Calculation of thermal-hydraulic condition is a necessary element for assessing the feasibility of decisions taken at all stages of control. An information and computer complex "ANGARA-HS" of the fourth generation was developed to solve traditional and new problems from the analysis and control of large HSS conditions.
