Abstract :
An engineering study has been carried out to enhance the reliability of the starting system of the salient-pole synchronous machines in a pumping-generating plant. The study involves an accurate prediction of the damper bar currents and temperatures during the starting process. Time-stepping finite element analysis for a multiple-pole model including coupled field-circuit formulation and rotor motion has been used. The predicted results are verified by experimental investigations.
