In the operation process

generator will be affected by many factors and cause various kinds of prob- lems

if we fail to find problems that coauld lead to serious consequences. The excitation generator fault simulation experimental teaching system is designed based on further studying the stator and rotor structure of the excitation generator. Two levels of generation structure are used in this system and fault set operation is simple. The system can simulate inter-turn short circuit

inter-phase short circuit of stator winding and the rotor eccentricity fault for main generator. It can also simulate inter-turn short circuit of stator winding and inter-turn short circuit

inter-phase short circuit of rotor winding for exciter. One power diode can be set at open-circuit fault in three-phase full-wave bridge rotating rectifier. The experiment system can realize the generator fault positioning and improve the operation reliability of generator.
