A Study on the Parameter Identification for Generator Automatic Voltage Regurator by Field Test

A new improved excitation control system for power plant synchronous generators has been developed by KEPRI(Korea Electric Power Research Institute). In this paper a description of the developed control system with detailed design concept is given. Field tests are conducted to show the system performance and to obtain the model parameters. Based on the measurement approached by field tests excitation model parameters supposing a mathmatical model is given can be determinded. This paper also proposes a algorithm of parameter estimation and identification in the synchronous Generator Excitation Control System.
