This system tests the fifth order machine with a type 2 AVR, from PSAT. Simulate the system for 20 seconds.
Variables of interest are related to the (non-)coherency observed between the synchronous machines:
order2.w
order5.w
Note that the oscillations, which present some considerable damping, have opposing phases, meaning that one machine is swinging against the other, in a clear example of non-coherent machines. In addition, plot:
bus4.v
bus5.v
Compare these results with the ones from the other example systems within the TwoAreaOld subpackage.
