Study of the Dynamic Performance of an Electrically Excited Synchronous Machine with Rotary Transformer

In this article, the influence of the rotary transformer design parameters on the dynamic performance of the electrically excited synchronous machine (EESM) has been investigated. The model of EESM in the d-q reference frame with the control system has been built and analyzed using Matlab/Simulink software. The main electrical parameters of the rotary transformer were identified and implemented into the equivalent circuit model of EESM based on the parameters of the real machine. Based on the proposed model, the most suitable design parameters for the wireless excitation system were obtained.
