Automation in Power Industry

Yeryghin S.Yu., Paustianov R.V., Spiridonov A.G.  Power plant digitalization: easy instrument tuning and diagnosis

The paper provides a case study of a smart instrumentation diagnosis system implemented at a power plant of Euro-Asian Power Corporation in Aksu (Kazakhstan) with the help of Emerson AMS Device Manager software.

Keywords: instrumentation, diagnosis, smart instruments, power plant, digitalization.

Zakharchenko V.E., Sidorov A.A.  On the digitalization of hydroelectric power plants

The concept of a digital twin of an enterprise is introduced and discussed. With examples of hydroelectric power plants, the components of power plant’s digital twin comprising its whole lifecycle are examined. The paper shows that the integrated digital approach results in significant savings from the cost of plant infrastructure ownership.

Keywords: digitalization, digital twin, hydroelectric power plant, 3D model, information model, concurrent engineering, modeling, virtual commissioning, training, optimization, predictive diagnosis, knowledgebase, information security.

Tverskoy Yu.S., Muraviov I.K.  Improving fuel and air feeding systems of steam-gas plants under changing operation and ambient conditions

Key factors affecting the operation efficiency of a power generating unit with a steam-gas plant were investigated on a mathematical model. Based on the study results, an automatic regulatory control system was developed for fuel feeding to combustion chamber and air supply to gas-turbine unit’s compressor. The results of control system investigation under changing operation and ambient conditions are presented, its efficiency is estimated under ambient air temperature variations.

Keywords: gas-turbine unit, steam-gas technologies, efficiency, power generating unit, mathematical and simulation models, structural synthesis, automatic regulatory control system.

Kochenghin A.E., Pavlyuk G.P., Shikhin V.A.  Statistical treatment of power consumption profile for process information retrieval

A new method for detecting large deviations in power consumption monitoring is offered. The method aims at improving the detection confidence of technological events. It allows to detect critical events and identify them in certain cases. By introducing the list of critical events, a table of their distinctive features and their characteristic functions was developed. For critical event identification, a feature-event mask is developed, which allows to reveal active features and distinguish the events with similar features. Numerical experiments with power consumption statistics made it possible to check the possible use of Wilcoxon signed-rank test in the critical event detection algorithm.

Keywords: technological event, event detection, critical events, load profile, characteristic function, nonparametric test.
