Rational maintenance and management of heating networks of the city

The solution of specific tasks of management and rational maintenance of energy systems of cities can be ensured by a constantly updated unified urban geographic information system. The article discusses the main possibilities of using geographic information systems to determine the reliability indicators of heat supply networks, increase their efficiency and manageability by the processes of their operation. The analysis of the technical condition of the heat network of the city of Voronezh, the statistics of accidents and repair work on sections of the pipeline. The main shortcomings of the existing reliability accounting system, which does not imply the process of managing repair and restoration work, are identified. The expediency of making operational decisions on the basis of up-to-date information on the condition of sections of the heating network in different areas of the city and different periods of installation and repair is proved. The necessity of creating a constantly updated, updated and updated database of all systems of the city of Voronezh using geographic information technologies is justified. The analysis of factors leading to the need for reconstruction of heat supply systems is carried out. It has been established that the most common reasons leading to the need for reconstruction of heat supply systems are: change in the number of connected consumers; change in flow, temperature or pressure in the heating network; mismatch of energy indicators of the system with modern requirements.
