Generator Synchronization Simulator

1. Match frequency and voltage. 2. Bring the needle close to 0°. 3. Close the G2 breaker, or try Automatic synchronization. Drag the control up or down. Hold Shift for fine adjustment, use the −/+ buttons, or enter a value and press Enter.

Example closing window: |Δf| ≤ 0.10 Hz · |ΔU| ≤ 5% · |Δφ| ≤ 10°. Identical phase sequence is assumed. Protection scenario after synchronization: f < 47.5 or > 52.5 Hz triggers the scenario’s “Reverse low power” alarm; U < 380 or > 420 VAC triggers “Overcurrent”. The relevant generator breaker opens. Boundary values remain permitted. Alarms persist until reset. This is a custom training scenario, not an actual power/current protection calculation.
