Improvement in accuracy of prediction of electrical machine constants and generator models for subsynchronous resonance conditions. Volume 1. Three-dimensional electromagnetic field analysis of electrical machinery. Final report

Volume 1 of this report describes the development of three-dimensional vector potential finite element techniques for the calculation of 3-D magnetic fields in turbine-generators and other devices. Both nonlinear magnetostatic and linear eddy current versions were successfully formulated and verified against known analytical solutions or simple tests. The magnetostatic version was demonstrated on turbine-generator geometry.
