The order is placed by AGP Metro Polska, the joint venture consortium responsible for the overall project. The order was booked in the third quarter.
ABB will construct four combined traction and auxiliary substations rated at 15 kV (kilovolt) / 825V DC (direct current) / 400V AC (alternating current) and three auxiliary substations rated at 15 kV/400V AC for the new Warsaw metro line 2, which is presently under construction and will connect the eastern and western parts of the capital city.
As part of the turnkey project, ABB is responsible for the design, engineering, supply, erection, commissioning and start-up of the substations including civil works. Each of the DC traction substations will be equipped with four transformer-rectifier groups rated at 2 MW (megawatt) each.The transformers will step down the voltage from the public grid and the rectifiers will convert AC into DC to power the metro cars. Key products to be supplied include medium-voltage switchgear with integrated protection and control devices, dry-type rectifier and auxiliary transformers, diode rectifiers, low-voltage switchgear, substation automation and the supervisory control and data acquisition (SCADA) systems. The project is expected to be completed by the end of 2013.
One of the substations will be equipped also with a 40 MJ (megajoule) energy storage system based on double-layer super-capacitors to exploit the recovered braking energy from the metro cars. ABB will be responsible also for the network management system, which will integrate with the existing system that manages metro line1.
