Fault detection and isolation is a challenging task in the control of large scale complex systems. In this work we proceed to the fault diagnosis of an electric power transmission system based on a fault diagnosis of hybrid systems method presented in our previous work. Power systems often exhibit complex behavior in response to large disturbances. Such behavior is characterized by interactions between continuous dynamics and discrete events. Components such as loads drive the continuous dynamics, while other components such as protection devices exhibit event-driven discrete dynamics. Therefore, power systems constitute an important case of hybrid systems for fault detection.
