Motor Starting
Simulate voltage sag from large motor inrush.
Supported Starter Types
Set starter_type on each motor component in the One-Line Diagram to model different starting methods.
| starter_type | Inrush Model | Key Parameters |
|---|---|---|
dol (default) |
Full locked-rotor current (6× FLC typical) | inrushMultiple |
vfd |
Current limited to vfd_current_limit_pu × FLC (default 1.1×) |
vfd_current_limit_pu, ramp_time_s |
soft_starter |
Voltage ramps from initial_voltage_pu to 1.0; inrush ∝ V² |
initial_voltage_pu (0.3), ramp_time_s (10) |
wye_delta |
Inrush = Ilr ÷ 3 during wye phase; full inrush after switch | wye_delta_switch_time_s (5) |
autotransformer |
Inrush × tap²; typical tap 0.65 | autotransformer_tap (0.65) |
