Micro centrale 20 kV en bord de route

Micro Plant 20 KV

Power supply to the HVA electrical mains with a 20 kV micro plant

Context

Project Type :

Temporary Energy

Location :

Ribeauvillé (68)
Logo entreprise Enedis

Problem

  • The customer had to undertake pruning work downstream of an HVA line to secure their mains
  • To do this, they had to stop the source substation supplying an aerial (network point)
  • ENEDIS wanted a solution to supply their network at 20 000 V and avoid any power cut for its users
  • The feasibility study had to take into account a tight installation site on the edge of the road

Solution

  • Supply, installation, testing and commissioning of a Micro Plant 20kV of 500 kVA:
    • Generator 500 kVA
    • 1 transformer HVA 2 000 kVA on semi-trailer
    • 1 tank of fuel 3 000 L
  • Mains protection provided by a neutral point coil and realisation of a grounding circuit
  • Continuous energy production over 8 hours
  • Duration: 1 day of operation
