Abstract
The paper considers the TGID-05 program and information complex designed for modeling and spatial and technological analysis of the set heat-hydraulic modes of centralized heat supply systems. It enables management of operation modes and complex development of complicated heat supplying systems with possibility of controlling calculated and the measured system operation parameters. A scope of the complex is creation of automated workplaces in the central and regional dispatching services, regime services, technological departments of the energy companies with joint production of electric and thermal energy. The solution is compatible with GIS, SCADA systems, automated systems of accounting energy resources, automated control systems for production.
