ALBINO PADILLA, I.; OLGUIN SALINAS, D.  e  ROMAN MESSINA, A.. Sensitivity Analysis of the Dynamic Behavior of a Salient-Pole Synchronous Machine Considering the Static Rotor Eccentricity Effect. J. appl. res. technol [online]. 2012, vol.10, n.5, pp.724-730. ISSN 2448-6736.

This paper presents the sensitivity analysis of the behavior of a synchronous machine using the winding function theory considering the effect of static air-gap eccentricity. The winding function theory as a method to calculate the inductances of synchronous machines from the geometry and the actual arranging of the windings is presented. Then, detailed numerical simulations are carried out to examine the impact of eccentricity on the steady state regimes. The important role of static eccentricity and its links with various symmetrical and asymmetrical operating conditions are discussed as well as its influence on the machine parameters and performance are investigated. Experimental and analytical parameter results are presented for a 60 Hz, six-pole laboratory synchronous machine connected to an infinite bus under various static eccentricity conditions.

Palavras-chave : Sensitivity analysis; static eccentricity; steady state regime; synchronous machine; unbalanced conditions; winding function.
