Digital Energy

Making electrical installations visible, remotely controllable and ready for the smart grid.

The digital substation

Reliable data, from the substation to the control centre

We design the substation's communication architecture, integrate equipment from different manufacturers and ensure that every piece of information reaches the right place at the right time.

  • IEC 61850SCL engineering (SCD, ICD, CID), GOOSE, MMS and Sampled Values messages, interoperability testing.
  • Supervision and remote controlSubstation HMI, SCADA, IEC 60870-5-104, DNP3 and Modbus gateways to the control centre.
  • Substation telecomsFibre-optic networks, industrial switches, PRP/HSR redundancy, RS-485 serial converters.
  • Time synchronisationTime distribution (NTP, PTP) for usable event records.
  • OT cybersecurityNetwork segmentation, access management and hardening of substation equipment.
