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_Slip1: excitation current ie = 0
• SMEE_Slip2: excitation current ie = 2 A
• SMEE_Slip3: excitation current ie = 10 A
• SMEE_Slip4: excitation current ie = 19 A

Plot the following variable(s)

• smee.tauElectrical against theta: electromagnetic torque against rotor displacement angle
• smee.abs_is[1] against theta: RMS stator current (of phase 1) against rotor displacement angle
• Q against theta: reactive power against rotor displacement angle
• smee.is[1].im against smee.is[1].im: locus of stator fixed stator current
• isr[1].im against isr[1].re: locus of rotor fixed stator current
