Abstract
An approach to determining synchronous machine parameters by low-voltage frequency response tests with the machine stationary will be described. The tests are simple and safe. In addition, they provide a more detailed and complete model of the machine than the accepted standard methods/1/. The standard tests rely heavily on the measurement of large transients. As such, they are susceptible to any changes in saturation during the course of the measured transient. Furthermore, the accuracy and resolution with which a single transient can be measured are frequently insufficient to provide the detail required to model the solid iron rotor of a turbogenerator. The test method described herein avoids both of these problems as well as providing complete q-axis data which is not done by the standard tests.Keywords
