Abstract

This paper presents a method to identify synchronous generator parameters from on-line data. An observer for estimation of synchronous machine damper currents is designed. The observer-estimator is used in a graphical user interface (GUI) application. Possible internal machine fault conditions can be detected and remedial action can be undertaken. It is desired that an algorithm be developed such that it will enable bad measurement detection and rejection so as to increase the reliability of the results. Secondary objectives include calculation of the error characteristics of the estimation; development of an index of confidence; study of which machine parameters can be estimated, and which cannot; and evaluation of alternative GUI features.
