EXCITATION SYSTEM have been classified so far, as well as on different Excitation current is provided by the excitation system, possibilities to regulate those systems. First, excitation which, according to [2], usually consists of autonomic system models are described and their advantages and voltage regulator (AVR), exciter, measuring elements, drawbacks are discussed. Further more, different power system stabilizer (PSS) and limitation and possibilities to regulate those systems are given, with special protection unit (Fig. 2). emphasis on newly developed nonlinear system regulation. Finally, it is explained that nonlinear system regulation Exciter is the source of electrical power for the field methods are much more complex than commonly used winding of generator and is realized as a separate DC or linear system regulations, but also have potential to improve AC generator. Exciter has its field winding in the stator, excitation system regulation of synchronous generators if and armature winding in the rotor. In case of AC further developed.
