Determination of rotating machine parameters for transients simulations

A rotating machine is a very complex device that involves electrical, mechanical and control systems. Therefore, the whole representation of a machine requires the specification of electrical and mechanical parameters, as well as control system data. The representation of the mechanical part and the control systems are only needed for low frequency transients. An accurate representation of the mechanical part is important for some specific studies, such as torsional oscillations (subsynchronous resonance SSR), transient torques or turbine-blade vibrations. This presentation is related to the determination of electrical parameters of AC rotating machines. It aims to summarize the most important procedures proposed up to date to obtain the parameters needed for representing AC rotating machines in transients simulations
