What is grid synchronisation?

Before grid connection, the voltage, frequency, and phase angle of the generator and the grid must match — incorrect synchronisation generates short-circuit currents and damages the generator.

What the AI reads from these values

What the AI reads
  • Deviation of the generator frequency from the grid standard (target value: 50.0 Hz)
  • Difference in voltage amplitude between the CHP unit and the grid
  • Phase angle difference to avoid short-circuit currents
  • Stability of the synchronisation signal as an indicator of plant integrity
Scenario

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 system reacts. It identifies the trend before the limit value is reached.

Why this matters

Precise synchronisation prevents destructive short circuits and ensures the service life of the generator components. By monitoring the parameters, uncontrolled load jumps are avoided. This guarantees a stable feed-in and protects the hardware from thermal overload. Real power (kW) · Reactive power (kvar) → — kVA apparent power Calculation path: √(real power² + reactive power²)
