Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
An electrically excited synchronous generator is 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 and plot (versus rotorDisplacementAngle.rotorDisplacementAngle):
- smee.tauElectrical
- currentQuasiRMSSensor.I
- electricalPowerSensor.P
- electricalPowerSensor.Q
- mechanicalPowerSensor.P
Default machine parameters are used.
