Determination of synchronous machine stability study models

Generator model parameters were determined in order to improve the accuracy of power system dynamic stability simulations. The standstill frequency response test method was used on several large generators to determine the various standard model parameters traditionally used to represent a synchronous machine. Line switching tests were performed on one of the generators. A standard generator model with parameters developed from standstill frequency response tests was utilized in a computer simulation of the line switching test to compare results. The validity check was no more accurate than that obtained when the standard model structure was used with parameters developed from design data.
