PROJECT TITLE :
Standstill Frequency Response Test on a Synchronous Machine Extended With Damper Bar Measurements
ABSTRACT:
Standstill frequency response (SSFR) take a look at knowledge from a salient-pole synchronous machine with reconfigurable damper winding are presented. In addition to the regular measurements, the damper bar currents are measured and used to get the stator-to-damper transfer functions. The take a look at is performed 3 times with physically totally different damper winding configurations. An extension to the standard SSFR take a look at analysis theme is advised, where the stator-to-damper transfer functions are included. The validity of the identified models is substantiated by comparison of the simulated and measured machine response to a drive torque step disturbance. It is found that the damper winding measurements can be incorporated within the analysis scheme to isolate the impact of the damper circuits. But, for a machine of the type studied, also the quality SSFR take a look at procedure yields models that are correct enough for Power System studies.
