ABB REC670 Bay Control Unit

Application

• The IED (Intelligent Electronic Device) is especially suitable for applications in control systems where the IEC 61850–8–1 Ed 1 or Ed 2 station bus features of the REC670 can be fully utilized.
• It is used for station-wide interlocking via GOOSE messages and vertical client-server MMS communication to a local station or remote SCADA operator workplace.
• This supports the architecture with distributed control IEDs in all bays with high demands on reliability.
• The IED can be used up to the highest voltage levels.
• It is suitable for the control of all apparatuses in any type of switchgear arrangements.
• The control is performed from remote (SCADA/Station) through the communication bus or from local HMI.
• Different control configurations can be used:
  • One control IED per bay
  • One IED common for several bays
• Interlocking modules are available for all common types of switchgear arrangements.
• The control is based on the select before execute principle to give the highest possible security.
