The article describes the main tasks that need to be solved when automating technological processes at TPS. Technological processes at TPS take place in difficult conditions, which complicates the management tasks. When creating an automated control system, modern software and technical complexes are used, which are developed by domestic manufacturers. The software and hardware complex allows you to solve all the problems of monitoring and controlling technological processes in all operating modes of power equipment. They can be used for both newly constructed and reconstructed energy facilities. The basis of the Software and hardware complex is programmable logic controllers that support medium and distributed automation. The article discusses some Russian-made controllers. Since 2019, the automated control system of the boiler-economizer is being designed by NVT-Systems at the Dzerzhinsk TPS. The implemented Software and hardware complex needs to be integrated into the existing automation structure, in addition, simplicity, reliability and redundancy are required. For these reasons, the REGUL500 controller was selected. The controller is characterized by very high performance, reliability, and the ability to work in distributed systems in real time. In addition, the advantages of the REGUL500 controllers are: high accuracy of the measuring channels; the possibility of hot-swapping modules of all types; resistance to external influences. The REGUL controller has a set of various Russian certificates of conformity.
