Influence of the temperature schedule of heating network and using differential pressure regulators on the reliability of heat supply systems

\nThe methods of increasing reliability of heat supply systems are analyzed. A digital twin of the existing heat supply system has been created. Various modes operation of the system are modeled and control and decision-making system in the conditions operation of the heat network is considered on the example of one of heat supply systems of the Republic of Tatarstan. The indicators of reliability of heat supply to consumers at using these methods are determined. As a result of the application of control methods and increasing reliability of the thermal power systems, probability of failure-free operation and the coefficient of hydraulic stability of heat supply system were calculated, the influence of the temperature schedule and the use of differential pressure regulators (DPR) on the reliability of the system in general were analyzed. Special attention is paid to the hydraulic balancing of the heat supply system to increase her reliability.\n
