EXACT RELATIONSHIPS BETWEEN PARAMETERS AND TEST DATA FOR MODELS OF SYNCHRONOUS MACHINES

ABSTRACT

In a recent paper the authors have presented a new method expressing the parameters of a synchronous machine model in terms of measurable time constants, without the traditional simplifying assumptions. The considered model is characterized by equal mutual reactances between armature, field and damper windings.

This paper shows the extention of the new method to the models with all three unequal mutuals and with two equal mutuals. The exact relationships between the parameters of the examined models and the test data are provided. Comparisons are made between new and old method results to demonstrate the discrepancies in values of parameters.
