Information

This example system shows how the resynchronization controller is used to connect Generator 2 back to the grid. Note that at 2 seconds, a signal is triggered to equalize voltage magnitudes on buses 3 and 4.

Simulate the system for 50 seconds. Variables of interest are:

  • B3.v
  • B4.v
  • G1.gen.SPEED
  • G2.gen.SPEED

Note the behavior of those variables before and after the connection of generator G2 to the main grid.
