Permanent magnet synchronous machine operated at mains

Information

Mains operated permanent magnet synchronous machine loaded with step torque

This example compares a time transient and a quasi static model of a permanent magnet synchronous machine. The machines start with zero load and synchronous speed. At time tStep the machines are loaded with nominal torque.

Simulate for 1 second and plot (versus time):

Test example: PermanentMagnetSynchronousMachine with inverter

Information

Open circuit test of permanent magnet synchronous machine

This example compares a time transient and a quasi static model of a permanent magnet synchronous machine. The machines are operated at constant mechanical angular velocity.

Simulate for 0.1 second and plot (versus time):

potentialSenor.phi|potentialSensorQS.abs_y[1]: potential of terminal

Note

The resistors connected to the terminals of the windings of the quasi static machine model are necessary to numerically stabilize the simulation.

Test example: PermanentMagnetSynchronousMachine fed by current source

Information

Simple field oriented control of permanent magnet synchronous machine

This example compares a time transient and a quasi static model of a permanent magnet synchronous machine. The machines are fed by a current source. The current components are oriented at the magnetic field orientation and transformed to the stator fixed reference frame. This way the machines are operated at constant torque. The machines start to accelerate from standstill.

Simulate for 2 seconds and plot (versus time):

smpm|smpmQS.wMechanical: machine speed
smpm|smpmQS.tauElectrical: machine torque

Note

The resistors connected to the terminals of the windings of the quasi static machine model are necessary to numerically stabilize the simulation.

Electrical excited synchronous machine operating as generator

Information

Electrically excited synchronous machine as generator

This example compares a time transient and 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.

Simulate for 30 seconds:

smpm|smpmQS.tauElectrical: machine torque

Since the rotor slip is very low the transient and quasi static electro magnetic torque are practically equal.
