Festive launch of the „Reconstruction of R 110 kV and T 110 kV traction convertor substation Pečky“
Pečky, 17 April 2012 – Within the scope of the modernization of the railway network of the Czech Republic, the „Reconstruction of R 110 kV and T 110 kV traction convertor substation Pečky“ was launched on this festive occasion. The investor of this significant construction is the Railway Infrastructure Administration, state organization (SŽDC); it is co-funded by the European Union from the Cohesion Fund within the Operational Programme Transport.
The traction substation Pečky is situated on I RailwayTransit Corridor in the track section Prague – Kolín ca 1.2 km from the railway station Pečky. The existing traction convertor substation with its distribution station 110 kV was built in 1957; its lifespan has now reached the limit. The traction convertor substation Pečky is a crucial feeding spot, both in terms of the power supply of the national and international rail transport, and for the Railway Research Institute in Velim and the 110 kV distribution system of ČEZ Distribuce a.s.
The technology of the 110 kV distribution station will be fully reconstructed and equipped with a state-of-the-art control system. Compared to the current situation, the transformer stands will be prefabricated covered with oil catch pits for 100% oil content in case of leakage. Two 110/23 kV transformers of 16 MVA output will be installed as well as a new gas-insulated 22kV box-type distribution station. The distribution station will be feeding three rectifying transformers, transformers of home consumption and transformers to feed 6 kV 50 Hz distribution for the power supply of the signalling installation. Also, the installed gas-insulated 6 kV distribution station will be of box-type. The 3 kV DC part for the power supply of the contact line system of the rail transport will be ensured through 3 box-type rectifiers on extension trolleys. Last but not least, it is important to mention new traffic control equipment for unmanned control of technological units of the traction convertor substation and 110 kV distribution station from the control system of the electrical control office in Prague.
During the reconstruction it is necessary to provide alternate power supply of 3 kV DC distribution for the contact line system and 6 kV AC distribution for the signalling installation. It is important to build in advance a provisional 110 kV feeder including a 22 kV distribution station, and to install 3 kV DC movable container substation, 6 kV distribution station to provide 100% power supply of the contact line system and the distribution system for the power supply of the signalling installation during the reconstruction.
The whole area will get a new look. Those parts of buildings that cannot be used for the new technology will be demolished and the remaining technological buildings will be fully repaired; everything will be enclosed with a fence and provided with lighting. The whole project also includes a new access road and drives inside the area.
The construction, the investor of which is the Railway Infrastructure Administration, will be followed by the construction of 110 kV distribution station of ČEZ Distribuce a.s. The main developer of the reconstruction of R 110 kV and T 110 kV traction convertor substation Pečky is SUDOP PRAHA a.s. and the contractor is Elektrizace železnic Praha a. s. The implementation of the construction will result in much higher reliability of the power supply system of the contact line system and of the power distribution for the signalling installation.
There will be no radical restriction onthe railway transport on I Railway Transit Corridor in the track section Prague – Kolín. Ing. Jiří Martínek, SŽDC´s Deputy DG for Rail Modernization commented on today´s festive occasion: „The reconstruction represents a complex of measures allowing to achieve a high-quality supply of electrical power for the contact line system, enhanced safety and reliability of technological equipment, including remote control and transmission of system information to the traffic control post and long-distance surveillance by means of camera surveillance systems. It is the basic condition to sustain the safety and continuity of the national and international rail transport on I Railway Transit Corridor. The implementation of the construction will markedly reduce the cost of operation, maintenance and elimination of ecological burden.“
The reconstruction of R 110 kV and T 110 kV traction convertor substation Pečky, which is to be completed in December 2013, is co-funded within the Operational Programme Transport from the Cohesion Fund of the European Union. National funds have been granted by the State Fund for Transport Infrastructure. The investment cost of the construction totals CZK 256,856,000; the maximum amount of the EU contribution may total CZK 192,282,530.
