In plain English

The UK Atomic Energy Authority is replacing an old control system at their 33kV electrical substation with a modern SCADA system (supervisory control and data acquisition). They need a specialist to design, build, install, and commission this new system, which will control and monitor the substation remotely using the latest IEC 61850 protocol standard.

What the buyer wants

• Design and manufacture a complete SCADA system to IEC 61850 protocol standard, replacing the existing CODAS system and PLCs • Install the system in the 400/33kV substation and an operator workstation in the J5 control room • Commission the system and integrate it with all devices on site, transmitting alarms and status signals over fibre or Ethernet to the main control room
