Introduction of digital automation in the Nizhny Novgorod electric depot

GK 1520 equipped the Nizhegorodskoye electric depot with digital Russian automation, which will serve up to 40% of the composition on the Big Ring Line of the Moscow Metro.

A feature of the metro is heavy traffic and large passenger traffic. Trains here run at much smaller intervals than on the railway. Digital control systems will ensure the reliability and safety of transportation with high line load, - said Konstantin Khromushkin, Deputy General Director for Innovative Development and Digital Transformation of the Group of Companies 1520.

Microprocessor systems for the development and production of the ZHAT GK 1520 Division will control the arrival of rolling stock in the depot for maintenance, regulate the operation of arrows and traffic lights, monitor equipment parameters, diagnose and detect pre-failure conditions.

The electric depot installed a microprocessor centralization system MPC-EL with built-in cyber protection, digital modules for monitoring rail circuits, as well as a digital modular feeder. Redundancy of components and data transmission channels guarantees high reliability of automation. Taking into account the specifics of the subway, all equipment is protected from dust and moisture.

Trains of the Big Ring Line will serve three electric depots: Zamoskvoretskoye, Nizhegorodskoye and Aminievskoye. The movement at all three facilities will be controlled by digital automation of the development and production of the ZHAT GK 1520 Division.

The Nizhny Novgorod electric depot is located in the Lefortovo area on the site of the Moscow plant for the modernization and construction of railcars named after Voitovich. The total area of ​ ​ objects exceeds 17 hectares - these are more than 50 buildings and structures, including a sedimentation and repair building for 30 trains, etc. Up to 288 cars a year will be repaired here.

Introduction of Russian digital automatic ring line

The 1520 group of companies in January 2023 announced that the specialists of the railway automation and telemechanics division (ZHAT) and the United Construction Company 1520 (USC 1520), which is part of it, reconstructed and equipped the ring line of the Moscow metro with digital Russian automation.

The ring line of the Moscow metro opened to passengers on January 1, 1950. The line includes 12 stations, the operating length is 19.4 km. The total length of auto-blocking (295 rail chains) is 38.8 km. The minimum intercity interval is 90 seconds.

Outdated relay devices on the ring line were replaced with digital ones "(photo - russos.livejournal.com)"

Instead of the outdated relay devices of 1954, the GK 1520 specialists installed modern microprocessor systems for monitoring rail circuits, microprocessor centralization, dispatching and automatic diagnostics on the ring line.

Rail chains are a means of monitoring the freedom of track sections and the integrity of rail threads, as well as transmitting signal readings from the way to the train. Microprocessor centralization system - an automated process control system that controls the operation of equipment (arrows, traffic lights, etc.), monitors and optimizes train routes, monitors equipment parameters, detects pre-failure states, etc.

GC 1520 explained to TAdviser that modern microprocessor automation for the development and production of its LAT division was introduced. These microprocessor systems make the most of Russian microelectronics, especially in the most critical nodes, the company says.

The new equipment, according to the developers, will reduce the intervals between trains by 10-14%. During rush hour, 36 pairs of trains will be able to pass along the line instead of 34, it will become freer in the cars.

It is also expected that metro personnel will be able to more effectively control arrows and traffic lights, control equipment parameters, draw up routes faster and regulate traffic schedules.

The Moscow Metro is one of the busiest in the world. The network of lines is continuously developing due to the construction and modernization of infrastructure, passenger traffic is growing. With high traffic intensity, the latest digital control systems will ensure the reliability and safety of transportation, guarantee uninterrupted operation of equipment, "says Konstantin Khromushkin, Deputy General Director of GK 1520 for innovative development and digital transformation.

After the modernization, the nature of threats to relay devices changed. So, for old relay systems and devices, threats such as the influence of the human factor, the absence of self-diagnostics, etc. But computer systems are already used to control relay devices, for which the issue of cyber threats is relevant, TAdviser explained in GC 1520.

The microprocessor centralization of the MPC-EL, installed on the ring line of the metro, has a built-in cyber defense system, which completely excludes unauthorized access to critical infrastructure, the company says.

During the reconstruction, new power equipment of traction substations of the ring line was also installed for reliable power supply to automation. Wire communication networks, fire and security alarm systems with automatic gas fire extinguishing, ventilation and air conditioning were reconstructed.

The specialists of GK 1520 performed most of the construction and installation work without stopping the line. Only for the time of equipment switching did it take to partially change the train pattern.

The digitalization of the metropolitan metro began in April 2021. Then the specialists of the ZHAT GK 1520 division installed their own microprocessor centralization system in the Sokol electric depot. This was the first experience in introducing its microprocessor centralization in the Moscow metro.

Currently, we have signed a contract for the introduction of modern microprocessor systems at new construction facilities in the Aminyevskoye and Nizhegorodskoye electric depots, - told TAdviser in GK 1520.
