What exactly causes rotor oscillations of a synchronous generator (while delivering complex power) during stages of under excitation.
Many thanks

If a generator is connected to a grid, and the grid is supplying lagging MVAR's (+ve circulating), is it possible to operate the machine at lower excitations and still remain in a safe operating region (as described by generator capability curves) than if the grid were supplying leading MVAR's...
I am currently analysing the process model code for a synchronous generator simulation. The model calculates the internal EMF of the machine under normal operating conditions (i.e. operating within its capability curves) as a function of the Automatic Voltage Regulator's (AVR) internal setpoint...
