Information
Description
At start time tStart a transient and a quasis static three phase voltage
are supplied to a transient and a quasi static the asynchronous induction machine with squirrel cage.
First the machines are star-connected, then delta-connected. The machines starts from standstill,
accelerating inertias against load torque quadratic dependent on speed, finally reaching nominal speed.
Plot the following variable(s)
imc.tauElectricalagainstimc.wMechanical: transient torque speed characteristicimcQS.tauElectricalagainstimcQS.wMechanical: quasi static torque speed characteristiccurrentRMSsensor.I: quasi RMS stator current of transient machinecurrentRMSSensorQS.I: RMS line current of phase 1 of quasi static machineimcQS.abs_is[1]: RMS stator current of phase 1 of quasi static machineimc.stator.electroMagneticConverter.abs_Phi: magnitude of stator flux of transient machineimcQS.stator.electroMagneticConverter.abs_Phi: magnitude of stator flux of quasi static machineimcQS.arg_vs[1]: phase angle of stator phase voltage 1, quasi static machineimcQS.arg_is[1]: phase angle of stator phase current 1, quasi static machine
