IEEE Recommended Practice for Excitation System Models for Power System Stability Studies

Excitation system and power system stabilizer models suitable for use in large-scale system stability studies are presented. Important excitation limiters and supplementary controls are also included. The model structures presented are intended to facilitate the use of field test data as a means of obtaining model parameters. The models are, however, reduced order models and do not necessarily represent all of the control loops of any particular system. The models are valid for frequency deviations of 5% from rated frequency and oscillation frequencies up to 3 Hz. These models would not normally be adequate for use in studies of subsynchronous resonance or other shaft torsional interaction behavior. Delayed…
