This example system represents a 9-bus 3-generator test system with a three-phase-to-ground fault at bus 9 and it must be simulated during 20 seconds.
Variables of interest are:
B1.vB2.vB3.vGen1.gen.deltaGen2.gen.deltaGen3.gen.deltaNote that the voltage curves present different acting modes. Also note that disturbances in the AVR reference voltage can be added to each generation unit.
