What is Substation Automation?
Substation Automation System (SAS)
Substation automation uses intelligent electronic devices (IEDs), protection relays, and communication standards such as IEC 61850 to monitor, protect, and control electrical substations locally and remotely.
How it works
Modern substations replace hard-wired control with networked IEDs that perform protection, metering, and control, communicating over IEC 61850. This enables faster fault clearing, remote operation via SCADA, condition monitoring, and detailed event records.
Frequently asked questions
What is IEC 61850?+
IEC 61850 is the international standard for communication in electrical substations, enabling interoperable IEDs, fast 'GOOSE' messaging for protection, and standardised data models for monitoring and control.
