Today Minsk metro is a complicated technical complex that through to 2020 consisted of two metro lines (Moscow and Avtozavodskaya) with a total length of 38.3 km and 29 passenger stations and 2 depots. Passenger traffic flow equals 970.2 thousand people per day, and the total amount of passengers per year reaches 318.5 million people.
Starting from November 07, 2020, the first section of the third line of the Minsk metro is available for passengers with 4 new stations "Kovalskaya Sloboda", "Vokzalnaya", "Yubileynaya Square" and "Frantishek Bogushevich Square" (civil and construction works were started in February 2014). The new metro line with a length of about 4.5 km connects Minsk center and Minsk southern and northern districts.
"Vokzalnaya" station
The uninterruptible and reliable power supply of the contact network of the metro line is provided due to 4 powerful substations equipped with advanced PLUTON equipment — DC switchgears 825 V and rectifiers with converter transformers RESIBLOC®.
In 2018 PLUTON Group started with a huge and complicated project — implementation of three independent automated operator's control systems (further — integrated telecontrol system) for Minsk metro, and namely:
- power supply control, including lighting systems for tunnels and stages;
- electromechanical equipment control — ventilation equipment, heat and water supply systems, etc.;
- control of 12 escalators and 9 passenger conveyors.
An integrated telecontrol system will provide the following functions:
- centralized control of power supply systems, environmental control systems, and other technological processes from operator's workstations;
- analysis of controlled equipment in a real-time mode;
- displaying of equipment state, warning, and emergency messages;
- quick displaying of diagnostics information concerning equipment operation and data transmission units;
- operational data output;
- generation of report documents.
For visualization, operator's control, data acquisition, and analysis PLUTON applied the cutting-edge software based on the open SCADA system Zenon by COPA-DATA (Austria), and microprocessor control systems as a part of equipment were based on PLC by B&R.
Reliable and safe PLUTON equipment as a part of integrated telecontrol system meets the requirements of international and European standards series IEC 61850 ("Communication networks and systems in substations"), IEC 60870 ("Telecontrol equipment and systems"), IEC 60870 ("Telecontrol equipment and systems"), IEC 62351 ("Power systems management and associated information exchange. Data and communications security").
Now PLUTON Group experts continue working on the implementation of the integrated telecontrol system for the Minsk metro, and putting it into operation is planned for 2021.
