Abstract
Starting from the derivation of separate models of a synchronous machine and a rectifier, a steady-state model and a dynamic model are derived. The dynamic model is a global, rather than a simple model, in which very fast phenomena, such as the ripple on the direct current, are neglected. For the estimation of the quadrature-axis machine parameters an easy method has been developed. A similar method for the direct-axis parameters is not yet ready: it appears to be impossible, using the well-known three-winding model, to estimate parameters which satisfy both the transfer function from armature voltage to armature current and the transfer function from armature voltage to excitation current. A comparison between the measured and simulated results shows that the (dynamic) model meets the requirements, except for the phenomena in the excitation winding.
