Finite Element Method modeling and analysis for aeronautic synchronous generator with damper windings on unloading and short-circuit conditions

摘要

Nowadays Finite Element Method (FEM) has been one of the focus issues on analyzing electromagnetic machines. To investigate the dynamic characteristics of aeronautic synchronous generator with damper windings, electric circuit model with damper windings has been established and two-dimensional transient solution has been executed in this paper. FEM results on unloading and short-circuit conditions with Magnet of Infolytica corporation have verified the accuracy and feasibility of ever growing electromagnetic coupling method.
