Electrical excited synchronous induction machine as generator

Two electrically excited synchronous generators are connected to grids and driven with constant speed. Since speed is slightly smaller than synchronous speed corresponding to mains frequency, rotor angle is very slowly increased. Two equivalent machines with different numbers of phases are compared and their equal behavior is demonstrated.

Simulate for 30 seconds and plot (versus rotorAngleM3.rotorDisplacementAngle):

• aimcM|M3.tauElectrical: machine torque
• aimsM|M3.wMechanical: machine speed
• feedback.y: zero since difference of three phase current phasor and scaled multi phase current phasor are equal
