The present work was developed to show the study of electrical protection of turbogenerators. The interest in the development of the work arose due to the relevance and complexity of the proposed theme. Turbogenerators are synchronous generators developed for thermoelectric power plants and can be applied to steam or gas turbines. Synchronous generators are elements of great importance within a power system and their failure or unplanned shutdown can cause serious instability in the electrical system if there is no other source of generation available. Because they are subject to various types of defects and failures, they have an elaborate protection system composed of protection relays, auxiliary relays and accessories. The main purpose of this protection system is to maintain a high level of continuity of service and, in the event of intolerable conditions, to minimize the size and time of disturbances. Its secondary function is to indicate where the fault occurred and the type of fault, facilitating the diagnosis and reestablishment of the systems involved. In this work the main protections applicable to turbogenerators are discussed, the theoretical bases for their understanding and a case study as validation of the developed content.
