Ensuring uninterrupted power supply to mining enterprises by developing virtual models of different operation modes of transformer substations

The possibility of real-time modeling of electrical power parameters of transformers will ensure continuous power supply to enterprises in the mining industry by quickly turning off transformers and automatically turning on backup sources. This article provides a description of the process of transferring electricity from the generation source to the consumer. An analysis of the most likely causes of damage to transformers at substations in the mining industry was also carried out. The main operating modes of transformers, including emergency situations at mining enterprises, are described, and the need to model various operating modes of transformers is emphasized. The article analyzes different methods for modeling transformer operating modes and proposes a methodology for studying created virtual models of transformers in various modes, including emergency situations at mining enterprises. The article puts forward a hypothesis about the possibility of simultaneous modeling of various emergency operating modes, such as single-phase, two-phase, three-phase and single-phase ground faults. After virtual modeling, graphs were constructed and data on electrical energy parameters were systematized, allowing the creation of databases for subsequent prediction of possible emergency situations in order to prevent them. Analysis of the modeling results confirmed the correspondence of the online models to the conditions occurring in the transformer substations of the mining enterprise.
