In order to validate the generator equivalent circuit models produced by fitting the parameters to standstill frequency response (SSFR) measurements, on-load generator data is required to be used to compare, match and iteratively improve simulated model responses. This report describes the results of on-load tests performed on the turbogenerator at Atikokan, Ontario, Canada and includes reports on the results of standstill and small-signal open-circuit tests in the Appendices. The on-load tests comprised the on-line frequency responses (OLFR), steady-state measurements for the purpose of determining direct and quadrature axis saturation parameters, and transient response measurements including line switchings and over- and under-excitation step changes. The OLFR measurements were not accurate enough to be used for generator model improvement. However, applying separate direct and quadrature axis saturation parameters to the SSFR equivalent circuit model produced the closest simulation match to the measured transients when compared to other equivalent circuit models of the Atikokan generator.
