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.
风能开关磁阻发电机6x4的动态性能分析
本文分析了开关磁阻发电机的动态性能随激励电压和磁化角的变化规律。通过傅里叶级数展开的相位电感表示,建立了包含磁路饱和的机器数学模型。由电感式推导出连杆磁通、能量和电磁转矩的方程。在Matlab/Simulink中进行仿真。给出了发电机在变励磁电压固定转子转速、变励磁电压固定转子转速以及最后改变发电机磁化角三个方面驱动的仿真和实验结果。
