“…The equivalent airgap length distribution function [5], [6], [11] is approximated as: (9) where the minimum airgap length is (α d (α' 1 +α' 2 )) -1 and the maximum is (α d (α' 1 -α' 2 )) -1 . The following assumptions are made for the equivalent airgap distribution function: − the average airgap distribution represented by α' 1 is dependent upon the saturation level (k sat (i m ,ρ)) defined by amplitude and angle of the magnetizing current; − the phase (ρ) of fundamental harmonic of the airgap distribution is dependent upon the angle of the magnetizing current.…”

Φ Abstract -For the evaluation of modern electric power systems with regard to their behavior, weight, and reliability a novel modeling and simulation tools have been developed. The paper presents circuit model of synchronous generator taking into account both the non-sinusoidal distribution of the stator and rotor winding, and non-uniform saturation of the pole shoes. This model is suitable for simulation of both salient and no-salient pole generators. Winding function approach is used to define the self and mutual inductance which has enabled to take into account the non-sinusoidal distribution of stator and rotor windings. The equivalent airgap length distribution function is used to model the shape of the salient pole rotor and non-uniform saturation of the pole shoe. Simulation and experimental tests were carried out to validate this modeling method. The developed model can be used to analyze an autonomous power systems, in which a single generator has a significant impact on the power quality.

The finite reluctance approach is based on a simple synergy between a basic magnetic domain decomposition rule and the voltage balance at the terminals of any winding acting in the domain. The finite reluctance approach is thought as a tool for fast dynamic simulations of any kind of machine, but it is particularly adapt for irregular flux geometries as in fractional-slot surface-mounted permanent magnet machines with large slots and high slot flux leakages, for which only the finite element method has found good usage. This approach is based on the definition of a complementary mesh interlaced with the reluctance mesh, on the concept of material cell, and on unique rules to carry out both reluctances and magneto-motive forces. At this scope, definitions of mesh nodes, co-nodes, and auxiliary nodes are shown. The iron saturation can be easily taken in account, as well as motion effects. The circuit flux linkages are elected as state variables for integration, and they are directly linked to the loop fluxes in the magnetic network. The finite reluctance approach has been applied in this paper for dynamic modeling of an inverter-fed permanent-magnet linear synchronous motor
