| Popis: | The concept of implementation of smart thermal grids or 4th generation heat supply systems is a priority for the development of district heating systems in Russia and is to become the best available technology (BAT) for all new and reequipped energy systems. This will help to reduce inappropriate losses of thermal energy, reduce the accident rate of power systems, increase their energy efficiency and reliability, and simplify the integration of modern renewable energy sources (RES) into existing energy systems.One of the key technologies needed to create such systems is the creation of digital twins of heating networks and simulation models of district heating systems. The paper describes the development of a digital twin for the section under consideration of the heat network. The developed experimental stand — a real physical model — was used as a section of the heating network. It was subjected to tests in order to determine the capabilities of systems for remote monitoring of heat carrier parameters, as well as modeling emergency situations in sections of the heating network. The experimental setup was also used for verification of the digital twin being developed. To create a digital model of the experimental stand authors used Matlab Simulink, ZuluThermo and SimInTech. The ZuluThermo program enables to create a digital twin that simulates stationary modes of the thermal system, Matlab Simulink and SimInTech — both stationary and dynamic processes occurring on sections of heating networks. The dynamic model of the heat supply system was used to simulate the process of mutual influence of heat energy consumers. As scenarios of dynamic processes, situations in Matlab Simulink and SimInTech that arise during the operation of automation at thermal points of consumers were simulated. It was shown the mutual influence of heat consumers on each other when regulating the heat load, as well as their influence on consumers who are unable to independently regulate their heat load. |
