Abstract: The synchronous generator is the essential element is high-power electric energy generation, and its
excitation system is vital for understanding its behavior. Thus, a synchronous generator connected to an infinite
bus, with its excitation modeled using bond graphs, is proposed. Given the size of these systems which entails
certain disadvantages the model is presented in two interconnected stages, with their junction structure defined in
a proposed lemma. The mathematical model of the complete system is obtained, and simulation results are shown.
Additionally, an external disturbance is applied to the mechanical coupling between the synchronous generator
speed and the speed input to the direct current generator, demonstrating that a condition of instability can arise in
the excitation and the system as a whole.
