Generator standstill frequency response tests have been used to derive dynamic models and equivalent circuits descriptive of machine behavior. Methods developed so far have relied on having the stator leakage inductance as a given or assumed value. Use of frequency response test data with stator open and voltage applied to the field and alternately with field open and voltage applied to the stator, in each case recording voltage and current in the excited winding and voltage on the open winding, permits derivation of stator and field leakage inductance. The method is illustrated and applied to limited published standstill frequency response test data. The results indicate variation of leakage inductance depending on the frequency of the tests. The reasons for such variations are explored and hypothesized.
