Abstract
For the analysis of subsynchronous resonance, computer models of an electric system have generally been based on a modified 60 Hz model with short-circuit equivalents for power sources and with loads neglected. Due to the importance of validating the electric systems model, AIMS has been developed to measure the apparent impedance as a function of frequency seen at the terminals of the study generator. AIMS has been successfully applied to an extensive power system. A description is given of AIMS and the significant modeling improvement realized by it application
