摘　　要：双九相储能电机是一种新型多相同步发电机,主发电机数学方程高达21阶。电机经整流器向负载放电时,电机转速、输出电压与电流不断变化,电机机械动态与电磁暂态强耦合,难以用解析方法进行分析。该文首先推导了双九相主发电机降阶等效三相电机数学模型,简化了双九相主发电机模型的复杂程度;其次,由于旋转整流器、整流器交流侧与直流侧高次谐波对系统有功功率传递和系统动态过程影响较小,忽略高次谐波,考虑交流侧基波和直流侧平均值作用的基础上推导了系统平均模型,进一步简化系统模型,提高系统仿真效率。在Matlab/Simulink仿真环境中建立双九相储能电机带整流负载系统的降阶等效平均模型,仿真结果验证了该模型的正确性与有效性。The dual nine-phase energy storage electrical machine is a new kind of multiphase synchronous machine,and the mathematical equation of its main generator is up to 21 orders.when the machine releases energy to load through rectifier,the rotate speed,output voltage and current is constantly changing,and mechanical dynamics is strong coupling with electromagnetic transient,which makes it difficult to analyze with analytical method.Firstly,the equivalent three-phase reduced model is derived to simplify the original model.Secondly,ignoring high harmonics due to the AC side and DC side higher harmonics of rectifier having little influence on the system’s active power transfer and dynamic behavior,considering the function of the ac side variable’s fundamental and dc side variable’s average,the system average model is derived to simplify the original model and promote the computation efficiency further.The equivalent reduced average model of dual nine-phase energy storage generator with rectifier’s load is established in the Matlab/Simulink software,and the effectiveness and correctness of the model is verified by comparing simulation results
