Monitored: continuous
The scenario: A drifting excitation shifts the cos φ without triggering a limit value, reactive power costs, or grid issues. The AI: detects the shift in proportion early and reports it before the protection reacts. It identifies the trend before the limit value is reached.
Preventive detection of grid instabilities prevents unpredictable downtime and costly damage to the CHP unit components. Continuous monitoring of the relay parameters enables proactive maintenance of the handover station. This minimises downtime and ensures the planned feed-in of active power into the public grid.
