Purpose: To analyse the equipment failures of the “NeVa” train cars utilizing data from the Nevskoye Metro depot. To establish the benefits of vector motor control in comparison to frequency control. To identify the imported equipment of the “NeVa” electric train, and to develop recommendations for substituting these imports in the train’s control system based on an analysis of the failures that occurred during operation, aiming to ensure the uninterrupted and safe transportation of passengers within the St. Petersburg Metro system. Additionally, a comparative analysis of imported components versus domestic ones will be conducted to facilitate the implementation of the traction motor control system for the “NeVa” electric train. Methods: Analysis of the “NeVa” train equipment failures utilizing operational data from the Nevskoye Metro depot. Identification of faulty elements by reviewing of train equipment malfunctions. Investigation of domestic alternatives to imported equipment. A comparison of the specifications for both domestic and imported microcontrollers. Results: The benefits of vector control for traction motors compared to conventional frequency control have been clearly established. Guidelines for choosing domestic alternatives to imported control system equipment for the “NeVa” electric train have been formulated. Practical significance: The domestic substitutes for imported equipment outlined in this paper will facilitate the efficient operation of the “NeVa” Metro electric trains, and the K1921VK01T microcontroller has the potential to serve as a foundation for import substitution of the “NeVa” train components.
