Development of Automatic Determination of Types of Damage System of the Main Equipment of HPP

The paper deals with the problems of designing and development of digital twins of relay protection and automation, which allows automatically determination of the equipment failure type. The definition of the failure mode is based on the method of analysing analog and discrete signals that are present in the technological data transmission network. As a result of the research, the algorithm of the digital twin of relay protection and automation was developed and tested at the operating hydroelectric power station. The algorithm runs in the digital environment of the software package SCADA WinCC OA. The digital twin aimed at reducing the failure detection and localization time, and improving the information content about relay protection and automation devices operating modes. The results could be implemented in the existing automated control system of the hydroelectric power plants for improving the personnel decision-making process. The flexible configuration allows not only adapting algorithm to any equipment, but also extending their functionality.
