Abstract

This paper presents a Switched Reluctance Generator dynamic performance analysis as a function of excitation voltage and magnetization angles. A machine mathematical model is presented including the magnetic circuit saturation through the inductance representation of the phases by
Fourier series expansion. The equations for the linkage flux, coenergy and electromagnetic torque are obtained from the inductance expression. The simulation was performed in Matlab/Simulink. Simulated and experimental results are presented considering the generator driven under three aspects: variable excitation voltage and fixed rotor speed, fixed excitation voltage and variable rotor velocity and finally varying the generator magnetization angles.
