Services

Setteidea provides engineering services in the railway field, metro and tram wire. The services concern the design and verification of the power supply for the electrical traction, rail operations planning and the study of the safety systems for the control of the railway traffic. Setteidea supports its customers both in the race during the system design

Systems for electric traction

  • traction studies for energy supply systems in direct current and alternating current :
    • voltage drops the pantograph and track potential
    • sizing of transformers, rectifiers, cables, overhead line ...
    • step voltages and contact
    • Energy consumption
    • Regenerative braking, energy storage systems on the ground and on board trains, braking resistors substation, DC / AC converters for energy recovery
    • calculation of short circuit current minimum and maximum
    • Calibration of the protections against short circuits
  • Check compatibility with European Energy TSI standards.
  • Design and verification of the land network, analysis of risks in the event of a fault or lightning strike
  • AC primary network :
    • of load flow studies, short circuit and harmonics
    • Power quality, voltage imbalances
    • studies for power factor correction of loads.
  • Studies, field measurements and implementation models for the evaluation and resolution of problems related to electromagnetic compatibility.

Planning for the year

  • Calculation of travel times and reversing the last stop
  • Design and verification time
  • Sizing of the fleet of vehicles
  • Scheduling personnel shifts and the rotation of the rolling stock

Signalling systems

  • Requirements definition
  • Check the impact on rail traffic (transport performance)
  • software development with different levels of SIL (Safety Integrity Level) from SIL0 to SIL4 in accordance with CENELEC EN50126 / 8/9
  • Implementation of real-time simulation hardware and software systems for the functional testing of equipment / signaling systems and the training of personnel :
    • testing and verification of products and equipment (ATP, interlocking, signal encoder, counting axes, ...)
    • integration testing and verification of complex systems, with under emulated systems (SW in the loop) or really interfaced to the simulator (hardware in the loop)
    • simulation of the entire rail system (creation of mirror system), with the interaction of the Traffic Control Center, the interlocking, on-board equipment and ground of signaling and train movement.
    • Automatic generation of test scenarios from the system data, automatic execution and reporting of the results
    • Commercial hardware platform based on PC and commercial interfaces (analogue and digital I / O)
  • Planning and execution of functional tests of equipment or system
  • Development of demonstrators / driving simulators, with integration of the wayside signaling system and on-board, 3D view of the line and riding school
