摘　　要：十二相整流发电机集直流电压脉动小、动态性能佳等诸多优点为一体,成为舰船综合电力系统中大功率供电模块的理想选择,但由于模型阶次高且整流系统运行模式复杂,导致脉冲负载作用下直流侧最大瞬态电压调整率解析计算困难。为此,对十二相同步发电机进行等效降阶处理,同时利用功率等效原则将直流侧负载折算到交流侧,建立起十二相整流同步发电机的等效三相同步电机模型。基于此给出十二相整流发电机在矩形波脉冲负载下直流侧最大瞬态电压调整率的解析计算方法,并通过时域仿真和物理试验验证了提出计算方法的有效性。Twelve-phase rectifier generator has advantages on smaller DC voltage ripple and more excellent dynamic performance.However,it will be harder to calculate its maximum transient voltage regulation under the pulsed power load due to its higher order and more complex operating modes.Therefore,the analytical method needs to be predigested in which the generator is reduced to the lower order and the DC load is converted to the AC side.The newly established three-phase synchronous generator is essentially equivalent to the twelve-phase generator in external characteristic,based on which the analytical calculation method of the maximum transient voltage regulation of twelve-phase rectifier generator with pulsed power load is given.Finally,a detailed simulation model under Matlab/Simulink environment and a corresponding principle prototype of the twelve-phase rectifier generator are established.Both the results of time-domain simulation and the physical experiment show that the proposed analytical calculation method of minimum output voltage of twelve-phase rectifier generator is sufficiently precise.
