Information

Description

An electrically excited synchronous generator is driven with constant speed. Voltage is controlled, the set point depends on speed. The generator is loaded with a rectifier.

Plot the following variable(s)

  • voltageSensor.v: DC voltage
  • filter.y: filtered DC voltage, multiplied by 1/sqrt(2*3)
  • setPointGain.y: reference voltage (set-point)
  • smee.ve: excitation voltage
  • smee.vs[1], smee.vs[2], smee.vs[3]: stator phase voltages of phases 1, 2 and 3
  • smee.is[1], smee.is[2], smee.is[3]: stator phase currents of phases 1, 2 and 3
  • terminalBox.starpoint.v: potential of star point
