PERMANENT MAGNET SYNCHRONOUS GENERATOR INTER TURN FAULT IDENTIFICATION USING STATOR CURRENT ANALYSIS
Paper i proceeding, 2013

A three phase permanent magnet synchronous generator is modeled both as a FEM model and an analytically model with an additional fourth winding that represents the faulty part of the machine. The faulty part is described as a fraction of the healthy machine. The proposed method can be used for multi pole machines as a general method for calculating the inductances is shown. Simulations show that the largest contributing parameter is the fault resistance, i.e. the contact resistance of the inter turn fault. FEM and analytical simulations show similar results but with amplitude an amplitude difference.
