The opening ceremony of Baku Metro Purple Line — stations "Avtovokzal" and "Memar Ajami-2", took place on April 19, 2016, in Baku with the participation of President Ilham Aliyev.
The construction of the "Avtovokzal" metro station was launched in September 2009. According to the project, the station consists of a platform, 8 exits, a ventilation passage, and two pyramids installed in the lobbies. The total length of the station complex is nearly 560 meters. The length of the new line stations platforms is 144 meters. It gives a possibility for seven train cars to enter the platform in comparison to five train cars as it was before. 20 escalators of different heights operate at the stations and passages, and 8 travelators are installed at the exits. There are elevators for people with disabilities.
The total length of the "Memar Ajami-2" station is 168,5 m. It has 3 exits. 17 escalators and elevators for people with disabilities are installed at the station of almost 12 thousand square meters and the exits.
Equipment produced by PLUTON provides a reliable power supply for the new section of the traction network of the Metro Purple Line. This equipment corresponds to modern standards in quality, reliability, personnel life and health safety, environmental protection, and equipment operation as a whole, in particular, GOST 22789-94 "Interstate standard. Low-voltage devices. General technical requirements and test methods" and IEC 61439-1: Low-voltage switchgear and control gear assemblies — Part 1: General rules, as well as several other international standards.
This project included the supply of six "turn-key" substations: two traction substations (TSS), two lighting and power substations (LPS), and two ventilation substations (VSS).
Company SYSTRA (France) was the General designer of the project. PLUTON specialists developed detailed design of power supply system, installation, adjustment works, as well as power supply facilities commissioning.
The scope of supply for six substations included a full range of PLUTON equipment for metro, as well as the other equipment, included in the set of supplies:
- medium voltage switchgear 35 kV;
- rectifiers together with converter transformers RESIBLOC;
- DC switchgears;
- switchgears;
- DC boards;
- cabinets with meters;
- charging-rectifying devices;
- SCADA system that provides control of substation electrical equipment, including ventilation substation equipment remote control at a distance of over 2 km. The system includes a substation duty operator workstation with developed specialized software, SCADA cabinet with controllers, and communication means. Equipment and basic software of leading world companies were used during the development of the SCADA system;
- voltage inverter cabinets;
- power factor correction units;
- capacitors;
- output terminals cabinets;
- accumulator batteries;
- auxiliaries transformers;
- cabinets with accumulator batteries;
- operating current cabinets;
- power cabinet;
- ventilation control cabinets;
- distribution cabinets;
- current relay modules;
- section boxes;
- switchgears for tunnels.
Lighting and power substation (LPS) “Avtovokzal” station
Substations equipment has high electrical and operational characteristics confirmed by type test protocols of IPH Institut (Berlin, Germany). Applied components have high mechanical and electrical reliability, ensure long service life (over 30 years) and do not often require periodic maintenance (once per 10 years).
Substations are unique, because they are equipped with modern automation and remote control means providing control, monitoring and protection of substations equipment.
Lighting and power substations are equipped with modern SCADA cabinets SHTM with backup controllers that support data transfer protocol IEC 60870-5-104 Network access for IEC 60870-5-101 using standard transport profiles, as well as programming standard PLC IEC 61131-3:2013 Programmable controllers — Part 3: Programming languages. Controllers interconnect equipment of all the six substations, collect and transmit remote control (RC), remote metering (RM), and remote signaling (RS) signals from all substations, and transmit them to the upper level. It is possible to control equipment with a laptop, PC, or another device by connecting to the SCADA cabinet by an external interface via Ethernet.
In the nearest future Purple line substations, the remote control will be possible from the Power operator room, which currently provides operator control, data collection, and power supply visualization of the main part of Red and Green metro lines substations.
Power operator room is also a unique project of PLUTON, which included development of automation system architecture, design, supply of software and hardware, as well as development of solutions for POR design and ergonomics. Power operator room is equipped with multifunctional video wall displaying condition of Baku metro substations electrical equipment.
Conceptual development of Baku Metro covers step-by-step expansion of existing infrastructure and creation of large underground transport network until 2030.
PLUTON congratulates Baku Metro with the opening of the new line. We wish you successful development and the opening of new stations!
