中文摘要：

双九相储能电机是一种新型的多相电机,且工作过程一直为动态过程,难以采用传统解析方法进行详细研究,所以采用数值计算的方法分析双九相储能电机系统动态过程是十分必要的。首先以双九相储能电机为研究对象,建立了其dq0坐标系的数学模型,阐述了电机内部多相绕组之间电磁耦合关系,进而采用隐式梯形迭代算法建立了其数值仿真模型,在PSCAD/EMTDC中构建了完整的双九相储能电机系统仿真模型并进行了仿真计算。通过与实验室的小型原理样机的动态试验数据对比,验证了所建仿真模型的正确性,为工程样机的各种性能分析和含有双九相储能电机的系统分析计算提供参考。

英文摘要：

The dual nine-phase energy storage electrical machine is a new type of multiphase machine, and its operation procedure is transient. It is not feasible to study the performance of such a system profoundly by the analytical method. Therefore, it is necessary to build the model of dual nine-phase energy storage electrical machines to calculate the dynamic process by using numerical computation in electromagnetic transient programs. An energy storage system with the dual nine-phase machine was introduced and taken as a study object. Firstly, a mathematical mode was established, and the complicated electromagnetic coupling relationship inside the multiple-phase windings of this machine was illuminated. Then, its simulation mode was built and simulated by the implicit trapezoid iterative method in PSCAD/EMTDC. The accuracy of the model and the validity of the proposed method are confirmed by comparison between the experimental simulation results and test results, which are obtained on tests of a prototype. Theoretical basis is established for the analysis of the performance of this machine and its related system.
