RESEARCH OF AUTOMATED CONTROL SYSTEM OF 300 MW POWER UNIT

Abstract

Adjusting the power of a 300 MWt unit is one of the most important processes in the power industry, as such units can more quickly transition from one mode of operation to another. That is why a detailed study of the dependence of boiler capacity on both internal and external factors is one of the main priority goals in the energy sector at this time. And a detailed study of the influence of various factors on power is necessary for a more accurate construction of an automated system for regulating the power of a power unit. Because knowing the properties of an object, its response to certain factors or other factors will make it easier to come up with a more optimized automated power control system. And that is why this issue must be taken very seriously, because it will depend on the stability of the boiler and the stability of power changes, depending on the influence of external and internal factors. In this work the emphasis was placed on two parameters. Namely fuel consumption and water consumption.

In this article, the influence of different types of automated control systems on the control results of the power unit capacity of 300 MW was investigated. In general, both different regulators and different types of automated control systems were considered to help improve the control process. All available automated control systems were compared with each other and the most effective of them was established by conducting research in the Simulink environment. A comparison was made between P - regulator and I - regulator. A comparison of a single-loop automated control system and a combined automated control system was also made. The comparisons were made by obtaining power control graphs in the Simulink environment. Conclusions are made on the need to use one or another control system and which regulator is more correct at the moment in these automatic control systems.
