摘要
针对某型航空恒速恒频交流同步发电机组的交流励磁机和旋转整流器部分,提出将励磁回路独立出来,降低系统阶次,并将电枢和负载回路独立计算,建立简化的数学模型,并对三种不同的工作方式推导出子周期划分和工作状态转换条件。通过Simplorer仿真分析,证明本方法可以方便地应用于交流励磁机带旋转整流器负载的瞬态特性分析,并可用来研究其他类型的整流输出发电机系统和整流电路。
As an AC exciter with rotating rectifier load in a certain aeronautic constant speed and frequency a simplified method is researched. It separates exciter circuit from total loop equations which would decrease system matrix order. Moreover, armature circuit and load circuit are calculated respectively. Furthermore, simplified mathematic model is established and period divisions and conversion conditions are summarized according to three kinds of working methods. Meanwhile, dynamic response waveforms are obtained with Simplorer. The simulation results verify the working principle of the mathematical model and convenience of proposed method for AC exciter with rotating rectifier load. It can also be applied to research on other rectified output generator system and rectifier circuit.
