Stator damper winding and electromagnetic parameters of turbogenerators

The increase of the load in specific active parts of 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. Its influence has been investigated using numerical methods, since classical analytic model according to the two-axis theory and Park's equations is not applicable in this particular case.
