Influence of stator damper winding on magnetic and vibroacoustic parameters of turbogenerators

The increase of the load in modern turbogenerators causes higher local heating, higher magnetic leakage, increased forces of the electromagnetic origin and the increased acoustic noise level. Stator damper winding is an active cage-shaped constructive element positioned at the outer stator core diameter. Presented numerical calculations show that the stator damper winding can influence on the decrease of acoustic noise, electromagnetic forces between stator package and frame and additional losses.
