cos φ during grid feed-in typically 0.9 to 1.0; the AVR regulates the excitation — a poor power factor burdens the distribution network and can lead to grid charges.

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.
An optimised power factor reduces the apparent power and thus minimises costs for grid charges. The avoidance of reactive power peaks protects the infrastructure from overheating. A stable cos φ value also ensures compliance with the technical specifications of the grid operator.
