Machine Modelling for Transient Stability Analysis in Distribution Grids - A Comparison of Synchronous and Induction Machine Models in Medium and Low Voltage Grids

Johannes Weidner, Lutz Hofmann

Abstract

The complete models for synchronous and induction machines are compared with selected approximated models. This is to validate the approximations for the utilisation in transient stability analysis in distribution grids. The results show that they can be used to simulate stable oscillations, but they lose their accuracy approaching the area of transient instability. The main reason is the active power exchange during faults, which is not jumping to zero as it does in high voltage scenarios.
