Ventilation/dehumidification — the silent 24/7 load, with heat recovery. Part of the glass family — like our glass BESS, biogas plant and CHP.
Grid frequency must remain in the range of 49.8–50.2 Hz; above 50.2 Hz or below 49.8 Hz, the grid protection disconnects the CHP unit from the grid — preventing islanding and grid damage.

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.
Stable frequency monitoring prevents uncontrolled shutdowns and protects the generator windings from thermal overload. Compliance with the limit values guarantees continuous grid connection and meets regulatory requirements for feed-in. A stable value of 50.0 Hz signals an optimal load flow in the CHP unit system.
