Turnkey Solution with Primary Systems and Station Control for the ÖBB Substation Tullnerfeld

Overview

Substation Tullnerfeld
Control cubicle for overhead lines

Intensifying economic relations between eastern and western countries of the European Union is supported by railway extensions. 4-track upgrading of significant sections is of most importance within Trans-European Networks (TEN).

As part of the newly-built route between Vienna and St. Pölten, an additional substation had to be built for the new section, the Unterwerk Tullnerfeld. The new substation acts as a 110 kV node which is connected to the substations of Wagram, Auhof and Absdorf.

ÖBB substations serve as 110 kV switchpoints as well as transformer stations for supplying the railway network at 15 kV.

ÖBB Infrastruktur AG commissioned Sprecher Automation as turnkey solution provider concerning the complete primary and secondary systems of the substation Tullnerfeld. Beside the 110 kV and the 15 kV switchgears as well as the overall station control system, this also included comprehensive services – from planning and calculations to commissioning in March 2012.

Outdoor control cubicle
SPREPOWER MV-M7 medium voltage switchgear (16.7 Hz)
SPRECON-E-C station computer
SPRECON-V460: 110 kV switchgear
SPRECON-V460: 15 kV switchgear

The primary technology consists of the 110 kV air-insulated switchgear including steel construction and the 15 kV medium voltage switchgear.

As components of the turnkey solutions, Sprecher Automation also provided:

  • Location diagram
  • Short-circuit calculations
  • Force diagram for steel construction
  • Foundation and grounding plans
  • Cable laying, stranding and piping plans
  • Wiring and terminal diagrams

 

SPREPOWER HV switchgear (110 kV)

The 13 high voltage bays are:

  • 6 x outgoing feeders
  • 3 x transformers
  • 2 x bus sectionaliser
  • 1 x coupling
  • 1 x feeder for mobile substation

Service range

  • Delivery and erection of steel construction
  • Delivery and installation of the complete earthing system
  • Delivery and installation of the 110 kV disconnectors and transformers
  • Complete stranding including terminal equipment
  • Delivery and installation of outdoor cubicles with bay computers and busbar protection
  • Cabling of all secondary systems
  • Testing and commissioning of the complete switchgear

 

SPREPOWER MV-M7 medium voltage switchgear (15 kV)

SPREPOWER MV-M7 (16.7 Hz) was specifically developed for traction power supply. The switchgear has already been installed in another ÖBB substation (Unterwerk Reith) before.

Service range

  • Delivery and erection of the complete switchgear including feeder-related overhead line testing
  • Delivery and installation of the complete earthing system
  • Complete cabling (30 kV, 300 mm²: 3-/4-fold per feeder)
  • Cabling of all secondary systems
  • Implementation of protection and control devices
  • Testing and commissioning of the complete switchgear

 

SPREPOWER auxiliary systems

Sprecher Automation also delivered all auxiliary systems (3 voltage levels) for the substation.

Service range

  • Installation of the 400/230 VAC 50 Hz distribution system for supplying lighting systems and sockets
  • Installation of the 220 VAC 16.7 Hz distribution system for supplying heating, switching devices and building
  • Installation of the 220 VDC distribution system for 110 kV control system supply, the 15 kV switchgear and the auxiliary systems including protection and control devices
  • Complete cabling of secondary systems
  • Implementation of protection and control devices
  • Testing and commissioning of the complete switchgear

 

SPRECON station control

Beside primary systems, Sprecher Automation also delivered the complete station control system for the substation Tullnerfeld.

The 13 HV bays (110 kV) are controlled by 11 SPRECON-E-C94 computers, which are installed into 3 outdoor cubicles. 13 SPRECON-E-C94 computers were installed into medium voltage compartments. Additional SPRECON-E-C96 computers control and monitor 44 overhead line connectors and all auxiliary systems.

The SPRECON station control system is based on a ring topology with optical fibres.

A specific function for feeder-related overhead line testing was implemented in the bay computers. This feature allows simultaneous testing of various feeders.

The protection devices are connected to the station computer via optical fibres.

The control center system SPRECON-V460 offers clear and secure control and monitoring of the overall substation. Furthermore, it features logging and archiving of process data.

In normal operation mode, the substation is tele-controlled from Meidling (15 kV switchgear) and from Innsbruck (110 kV switchgear).
