Electric Stock Digital Twin in a Subway Traction Power System

详细

An approach to designing subway traction power supply facilities with an 825-V traction power system is considered in a general digital model. The continuously increasing passenger traffic in metropolitan cities makes it necessary to build new subway lines and upgrade existing ones, taking into account the compliance with all the standards of ensuring uninterrupted power supply at minimal electric stock (ES) train-to-train spans. The ES is also being upgraded, which includes the commissioning of new-type Moscow cars. To maintain the rates of commissioning new subway lines, the quality of design must be improved and the design process must be relocated to the digital environment. An example digital model (twin) of subway traction power system is exposed, as well as its application to estimating the dynamic behavior of ES.
