SMR_InverterTest example: SynchronousMachineReluctanceRotor with inverter |
This information is part of the Modelica Standard Library maintained by the Modelica Association.
An ideal frequency inverter is modeled by using a VfController and a three-phase SignalVoltage. Frequency is raised by a ramp, causing the reluctance machine to start, and accelerating inertias. At time tStep a load step is applied.
Simulate for 1.5 seconds and plot (versus time):
Default machine parameters are used.
