Simplification and unification of IEEE standard models for excitation systems

•Generalization of dynamic models for excitation systems.•IEEE classification of exciter types into alternator-supplied rectifier and static excitation system is reorganized into non-controlled and controlled rectifier types.•Three common universal excitation control models are developed for the non-controlled and controlled rectifiers and DC types excitation systems.•Proposed simplification may facilitate a data collection of the dynamic models for large power system studies.

This work proposes the generalization of models for excitation systems. Thirteen models according to IEEE standard are reduced to three main types by the development of a common universal excitation control model. The original IEEE division of exciter types into alternator-supplied rectifier and static excitation system is rearranged into non-controlled and controlled rectifier types. This division is suitable for model classification and for authors and users of network simulators. Proposed simplification may facilitate a data collection of dynamic models for studies of large power system.
