Abstract
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.
Highlights
Automation of technological processes at a thermal power plantThe production of heat and electricity directly depends on the process of extracting energy resources
Technological processes at the thermal power plants (TPS) take place in difficult conditions, which are characterized by the continuity of consumption and the impossibility of storing finished products; fast flow of processes in the turbine generator and large delays along the main channels of control actions in the steam boiler; constant risk of severe accidents due to high steam parameters and flue gas temperatures, etc
Achievement of the main goal of power unit control with the simultaneous performance of their functions by the automated control subsystems of the boiler unit, turbine and generator is associated with the introduction of a unified automated process control system at thermal power plants, designed to generate and implement control actions in accordance with the accepted control criteria [14, 15]
Summary
The production of heat and electricity directly depends on the process of extracting energy resources (coal, fuel oil, gas). Technological processes at the TPS take place in difficult conditions, which are characterized by the continuity of consumption and the impossibility of storing finished products; fast flow of processes in the turbine generator and large delays along the main channels of control actions in the steam boiler; constant risk of severe accidents due to high steam parameters and flue gas temperatures, etc All this complicates the tasks of managing TPS. Modern software and hardware complexes are a complex of microprocessor-based automation equipment, which includes microprocessor controllers, communication devices with an object, operator display panels and servers for various purposes, industrial networks that allow connecting the listed components They are intended to create distributed control systems for technological processes with various information capabilities. Achievement of the main goal of power unit control with the simultaneous performance of their functions by the automated control subsystems of the boiler unit, turbine and generator is associated with the introduction of a unified automated process control system at thermal power plants, designed to generate and implement control actions in accordance with the accepted control criteria [14, 15]
