Abstract

For an implementation of the finite element analysis in the design optimization of large synchronous machines, the efficiency of modeling and analysis methods is of great importance. The presented modeling and analysis methods utilize only one finite element model for all angular rotor positions without any remeshing. These methods are applied to the nonlinear finite element analysis of the salient-pole hydro-generators at the Bieudron power plant in Switzerland. The comparison with measurements of the steady-state parameters shows an excellent agreement and validates the proposed methods
