Information
Description
This example investigates a quasi static model of a electrically excited synchronous machine. The electrically excited synchronous generators are connected to the grid and driven with constant speed. Since speed is slightly smaller than synchronous speed corresponding to mains frequency, rotor angle is very slowly increased. This allows to see several characteristics dependent on rotor angle.
The intention is to compare the results of the following simulation models in one plot:
- SMEE_VCurve1: mechanical power
Pm = 0 - SMEE_VCurve2:
mechanical power
Pm = -10 kW - SMEE_VCurve3:
mechanical power
Pm = -20 kW - SMEE_VCurve4:
mechanical power
Pm = -30 kW
Plot the following variable(s)
smee.abs_is[1]againstsmee.ie: RMS stator current against excitation currentPagainstsmee.ie: active power against excitation currentQagainstsmee.ie: reactive power against excitation current
