This system is tests the third order machine with a type 1 AVR, from PSAT. Simulate the system for 20 seconds.
Variables of interest are related to the (non-)coherency observed between the synchronous machines:
order3.w
order3_1.w
Note that the oscillations, which are not well damped, have opposing phases, meaning that one machine is swinging against the other, in a clear example of non-coherent machines. In addition, plot:
B6.v
B30.v
Compare these results with the ones from the other example systems within the TwoArea subpackage.
