ANALYSIS OF EXISTING SOLUTIONS FOR IMPROVING THE MEASURING AND COMPUTING COMPLEXES OF HEAT SUPPLY NETWORKS

In the presented article, the team of authors considers the existing methods and the main modern technical solutions that are currently implemented in different countries in the diagnosis of heat supply networks. There is a selection of the main directions in the development and design of heat supply networks, which have already been implemented or supported by scientific teams from different countries. Various methods and technical features of diagnostics are reviewed, strengths and weaknesses of the presented solutions are highlighted. The reviewed works were subjected to detailed analysis, which revealed the presence of a high interest of the scientific and industrial community in the integration and improvement of existing digital technologies in the development of heat supply systems, which would be closely related to forecasting and modeling processes in this industry. The team of authors highlights the main vectors for the development of this sector, citing an example of a significant increase in the degree of digitalization of final products, which makes it possible to use data analytics to obtain effective technical solutions regarding heat supply networks. Separately, the positive experience of different countries in this industry is noted when using neural networks not only in the design of heat supply networks, but also as a target industry as a whole. Assumptions are put forward about the need for a detailed analysis of the existing foreign and domestic experience, as well as scientific developments in this area, in order to determine the most suitable technical solutions on the territory of the Russian Federation, which will take into account the climatic characteristics of the country and be based on methods of large data analysis, computer vision and simulation. modeling.

The paper addresses the issue of optimal expansion and reconstruction of heat supply systems, which includes a set of general and relatively specific problems. Therefore, a comprehensive approach to their solving is required to obtain a technically admissible and economically sound result. Solving the problem suggests search for effective directions in expansion of a system in terms of optimal allocation of new heat sources, their type, output, operating area; construction of new heat networks, their schemes and parameters; optimal detection of “bottlenecks” in the system and ways of their elimination (expansion, dismantling, replacement, strengthening of heat pipeline sections, construction of pumping stations and other components of heat supply networks). The authors present a mathematical statement of the problem, its decomposition into separate subproblems and an integrated technique to solve it. Consideration is given to a real problem solved for a real heat supply system. A set of arising problems is presented. The application of developed methodological and computational tools is shown.

Supply Systems

The main directions of increasing the efficiency of combined production of electric and heat energy are considered, associated with the improvement of power generating equipment, regime and circuit changes in heat supply systems while ensuring heat load. For many years, centralized heat supply based on combined heat and power generation has been successfully developing in Russia, which is a very attractive energy and nature saving technology. Its use makes it possible to save about 20 million tons of fuel annually, which is about 14% of the total volume of fuel consumed in Russia for the needs of heat supply. More than 50% of electricity is generated at CHPPs in Russia, and the efficiency of fuel use at them reaches about 70–75%. Such areas include the use of steam and gas technologies (CCGT units and gas turbine superstructures of equipment of operating CHPPs) and GTU-CHPPs, increasing the initial steam parameters at CHPPs, superstructure of hot water boilers with gas turbine units, improvement and modernization of existing turbine equipment and CHPP schemes, as well as rejection of peak boilers in favor of peak boilers at CHPPs, transition to a lower temperature schedule and a change in the structure of heat supply systems. The main advantages of these areas and the problems associated with their implementation are presented. The conditions of possible and expedient application of some directions are considered. It is shown that, in many respects, the choice of certain technical solutions, despite the energy efficiency, is determined by the conditions of the regional heat and electric energy markets.
