Zusammenfassung:	This paper describes the techniques employed for extraction of device parameters for a 20 MVA hydro-turbine generator in the Tennessee Valley Authority (TVA) power system. Several approaches were implemented in the extraction of parameters. Measurements on the generator were made prior, and subsequent, to extensive rework as part of a generator upgrade project. In addition, static exciter and overall response tests on the complete system were performed after the upgrade. The identified generator parameters before and after the upgrade are compared.
