From a unit trip to a confirmed cause in an hour, with the report drafted

The problem

After a unit trips, an engineer pulls alarms, sequence-of-events records and SCADA data by hand, often in the evening, to work out what happened before the unit can safely return. Every hour of that work is an hour the unit stays off and power is bought to replace it.

What we ran

Faults and protection operations injected into a plant and its interconnection on the model, generating the alarm stream so the true cause of each event is known.

What the agent did

It compresses the alarm flood, builds the sequence of events, proposes the cause, attributes customer minutes correctly, and drafts the event report and breakdown log. The engineer confirms the cause and releases the unit.

Run it on your network

Alarm and sequence-of-events records from two past trips. We replay them and show the cause the agent reaches, and how fast.
