本文开发了一种合成加载方法，适用于具有多个三相分布绕组的多相电机的测试。首先针对具有k个三相定子绕组的结构（即，相的总数为n = 3 k）。随后的详细发展描述了双三相（六相）定子绕组配置。控制架构允许将三相绕组的一半用作电动机，另一半用作发电机，因此可以在全额定功率下测试电机（和/或转换器），而无需任何机械负载。此外，从电网消耗的功率本质上仅等于系统的总损耗。基于双d-q方法建立了永磁同步电机的数学模型，并给出了包括全交叉耦合解耦的控制方案。文中还介绍了一台150 kW双三相永磁电机的实验装置，并给出了实验结果，验证了理论分析的正确性。
This paper develops a version of the synthetic loading method, suitable for the testing of multiphase machines with multiple three-phase distributed windings. The method is at first discussed in general terms for a structure with k three-phase stator windings (i.e., total number of phases is n = 3k). Subsequent detailed development is described for a dual three-phase (six-phase) stator winding configuration. With a control architecture that allows the use of half of the three-phase windings as a motor and the other half as a generator, the machine (and/or the converter) can be tested under full rated power without the need for any mechanical load. Moreover, the power consumed from the grid is in essence equal only to the total losses of the system. Modeling, based on the double d-q approach, and the control layout that includes full cross-coupling decoupling are described for a permanent magnet (PM) synchronous machine. An experimental test rig with a double three-phase PM machine of 150 kW rating is detailed and the samples of experimental results are provided to verity the theoretical considerations.
