Obtenção de parâmetros dinâmicos da máquina síncrona de polos salientes através de ensaios de resposta em frequência

Abstract

In this paper, initially on time domain, the constructive and electrical characteristics of the synchronous machine will be analyzed in order to define the equations that represents the dynamic behavior of synchronous generators. Linear transformations and arbitrary systems of coordinates, such as the direct and quadrature axes (d and q), will be used to facilitate the analysis. Defined the equivalent circuit of the synchronous machine, a frequency domain analysis will be taken in order to translate the machine behavior in terms of transference functions and operational parameters using a small signal model. After a short revision of parameters identification methods, an application of a standstill frequency response test will be related so that the results can be simulated to validate the proposed model.
