This example is composed by the 14-bus 5-machine system representing an approximation of the American Electric Power system. Note that the network is also composed of 11 loads and that three machines are acting as synchronous condensers.

The system undergoes a three-phase-to-ground fault on Bus 4 at 1s, lasting for 200ms. Simulate the system for 10 seconds.

Variables of interest are the voltages in which the synchronous machines are connected:
