Traction substation at Nedakonice matches modern trends after reconstruction
Přerov/Nedakonice, 13 October 2014 – The second stage of the traction distribution station at Nedakonice railway station is finished. The festive completion of the construction having been carried out since the beginning of last year took place today in Přerov. Its implementation allowed decreasing operation and maintenance costs and eliminating the environmental burden in the station’s premises.
The 110 kV converter and distribution station at Nedakonice railway station is an important feeding point of the Czech Railway Transit Corridor II, ensuring power feeding for domestic and international railway transport on both Czech traction systems (3 kV DC and 25 kV, 50 Hz AC). It was built in 1985 together with completing the electrification of the whole line between Břeclav and Přerov. In order to maintain operability, current and very high voltage transformers were reconstructed first in the initial stage in 2008.
The currently finished construction included reconstruction of very high voltage device equipment in individual fields, as well as armature, connecting cables, the grounding and related cable distribution system. In the technological part of the 110 kV distribution station, adaptations were carried out on the controlling system, own consumption technology and connection to remote control technology including transfer on optical transmission paths to the relevant electrical control centres. Installing modern equipment also allows remote traffic control from workplaces in Brno and Přerov.
The construction part consisted in adapting steel constructions of individual voltage sections, footings, cable channels and transformers’ sites including the wiring. The current transformers’ sites were roofed; rainfall from the roofing is now being drawn away to the newly built soaking pit. The current oil catch pits on individual sites were rebuilt to emergency wells in order to catch oil from transformers by 100%, which allowed eliminating the main oil catch pit. Another part of the construction was also reconstructing the current distribution station’s grit field surface and the road panel surface around the service building as well as the distribution station’s fencing.
Total construction costs amounted up to more than 84 Mio CZK. The project was co-financed under the Operational Programme Transport by the EU Cohesion Fund by 83,11% from eligible construction costs which means a sum amounting up to 55.799,893 CZK at maximum. National resources were provided by the State Fund for Transport Infrastructure. The construction’s supplier was the association of companies SIGNALBAU and OHL ŽS.
