On this tour we will visit the ABB ENVILINE™ Energy Storage System, the first European Energy Storage System in Subways and the largest of its kind in the world) and the Power Electronics and Applications Research laboratories of the Warsaw University of Technology (WUT).
The tour will start at the WUT with a short presentation about the ABB ENVILINE Energy Storage System. After that, the tour will take us, by the Warsaw Subway, to the Stadion Narodowy Subway line 2 substation, where the ENVILINE Energy Storage System is installed. Subway line 2 is one of the largest projects in Warsaw. The central section of the line is 6.1 km long and links the eastern Praga district with the downtown and western districts via a tunnel running eight meters below the Vistula river. The line, an investment of around one billion Euro, was opened in March 2015 and serves since about 100,000 commuters per day. The central section of Warsaw’s Subway line 2 is powered by seven underground substations – installed by ABB – providing DC traction power to the line and AC auxiliary power to the Subway stations. Four combined traction and auxiliary substations are equipped with four transformer-rectifier groups each to ensure redundancy and uninterrupted power supply, while the remaining three AC substations provide high-quality power to stations and commercial loads. To improve the ecological footprint of the new east-west connection, the Stadion Narodowy substation is equipped with a super-capacitor-based DC wayside Energy Storage System. The 40-megajoule system recovers and stores braking energy from decelerating subway trains and makes it available again for acceleration. This special feature helps to reduce operating costs, while enhancing energy efficiency.
After this interesting visit, the tour will guide us back to the WUT, where the most interesting and important Power Electronics and Applications Research laboratories will be shown. Recent achievements in the field of Power Electronics and Applications will be presented by the members of our scientific teams from the Institute of Control and Industrial Electronics (ICIE). The teams from the Industrial Electronics Division and the Electrical Drives Division of ICIE are currently involved in the Projects related to renewable energy sources, intelligent solutions for smart grids, electric vehicles and light aircrafts, and others. Selected solutions in these fields will be shown to the tour participants.
