TVA Plants Excitation System Modeling Review and System Performance Improvements – Tennessee Valley Authority (TVA), USA

Objectives/background/needs: TVA wanted to develop and update the grid model with latest exciter systems information.  This was required to ensure that grid model has all the parameters updated as has been changed on site.  For modeling accuracy investigations it was frequently observed before that this data base was not updated.

Key deliverables and solution provided: Initial Data Review and Logistics, Describe Current Excitation System Models Used. Site visit,  inspection. Derivation of model structure and preliminary settings. Identify the existing ‘As found’ excitation system model data in PTI PSS/E format. Identify Testing to complete PSS/E model data. System studies to  excitation system settings, System studies to evaluate excitation system settings improvements.  Report.
