The enormous amounts of energy consumed today for the production of thermal energy intended for households, on the one hand, and the reserves of all types of fuels available worldwide, on the other hand, require that a more rational consumption should be implemented among all consumers. One of the many enhancements to heating systems that aims to improve overall efficiency is the concentration of thermal energy output for a greater number of users, which produces a far better result. This has led to the implementation of a centralized supply of thermal energy for multiple buildings and facilities, residential blocks, and entire urban areas. This method of producing and transmitting thermal energy for heating purposes is called district heating. The thermal energy, produced centrally, is transferred via pipelines to substations, and then through heat exchangers and secondary networks to end-users. Due to the fact that energy consumption constitutes a significant part of the budgets of individual and collective users and requires compliance with the European Union directives on increasing efficiency in all spheres of energy transformation, there is a need for optimized production and consumption of thermal energy. Optimization involves adequate supervision of relevant parameters of the heating process, including production (boiler room), distribution (pipelines), transfer (substations), and consumption (end-user). Supervision entails the ability to command and monitor the operation and parameters of the process. To achieve this goal, the supervisory system must collect and display important process data to detect possible problems or causes of inefficiency in the process itself, thereby alerting the operator. The main goal of the supervisory system is to enable the operator to control and command a highly automated process. Therefore, supervision involves a series of tasks aimed at controlling the process and monitoring its parameters. The Supervisory Control and Data Acquisition (SCADA) system has wide application in district heating systems for monitoring, control, and data acquisition.
