Information

This example system represents the resulting model after one has followed the steps to assemble the generation unit and the network. The system must be simulated during 10 seconds.

Variables of interest are:

  • B1.v
  • B2.v
  • G1.machine.delta

Note that these curves have oscillations that grow with time, indicating a clear case of instability. This issue is addressed on Example 2.

Also note that validation against PSAT can be performed by loading the file Tutorial/Additional_Material/PSAT_dyn.csv. The correspondent curves are:

  • PSAT_dyn.v corresponds to G1.machine.v
  • PSAT_dyn.vf corresponds to G1.avr.vf
  • PSAT_dyn.w corresponds to G1.machine.w
