摘要
针对感应子发电机带整流器的独立电容充电电源系统的换流及负载动态特性进行了深入的分析。首先根据不同的负载电流得到相应的换流重叠角,然后依照各换流重叠角区间划分系统在不同阶段的工作模态,分别对不同的工作模态建立了简化的平均值数学模型,并推导出负载特性。通过Matlab/Simulink仿真分析,验证了本方法可以正确、方便地应用于交流发电机带整流容性负载的瞬态特性分析,并可以推广到其他类型独立的交流整流电容充电电源系统。
This paper presents the commutation and load dynamic characteristics of homopolar inductor alternator with rectifier independent capacitor charging power supply system.The operation mode according to different commutation delay angles which depend on the load current is classified,and a simplified average-value mathematic model is established.Furthermore,the load characteristic under every operation mode is derived.Meanwhile,dynamic analysis waveforms are obtained with Matlab/Simulink.The simulation results verify that the proposed method can be applied in the transient analysis of alternator with rectified capacitive load correctly and conveniently.It can also be extended to other types of independent AC rectifier capacitor charging power supply system.
