INFLUENCE OF REGIME AND OPERATIONAL FACTORS ON THE DAMPER SYSTEM OF THE SALI-ENT-POLE SYNCHRONOUS MACHINE ROTOR

The physical processes in the damping system of salient-pole synchronous machine rotor, which cause gradual destruction its structure, have been studied. In particular, distributions currents, temperatures and thermomechanical stresses rods during operation asynchronous asymmetric modes operation, as well case rotor eccentricity. A field mathematical model has developed that takes into account combined action three fields different nature: electromagnetic, temperaturic, stress fields, allows estimating heating loads machine. According to results analysis, structural elements were determined recommendations for improvement given. References 9, figures tables 1.
