本文提出了一个精确匹配仿真模型支持的实验测试装置，该仿真模型使用DSIM的可变时间步长功能执行混合逆变器/电机仿真，从而实现在几分钟内完成几秒钟的电网运行仿真。

“由于采用了DSIM离散事件仿真求解器，仿真软件大约以实时仿真速度的1/20运行。这意味着只需几分钟的执行时间就可以仿真几秒钟的电机运行。这种快速仿真不仅意味着可以快速评估系统软件或硬件的任何修改，而无需进行实验研究；并且可以快速完成多台并行运行的逆变器与负载仿真测试装置单元，并且不会丢失任何高频信息，例如微秒逆变器开关事件。这样的性能对于电机/功率变换器系统的实际仿真、研究和验证至关重要。”

“The software executes in approximately 1/20th of real time because of the DSIM discrete event simulation solver. This means that several seconds of machine run time can be simulated with only a few minutes of execution time. This rapid simulation turnaround not only means that any modifications to the system software or hardware can be quickly evaluated without requiring experimental investigation, but also that the simulation can be scaled up to include multiple test set units operating in parallel with modeled inverter and loads, still executing in a reasonably short time frame and without losing any high frequency definition such as microsecond inverter switching events. Such a performance is key to realistic simulation, investigation and validation of mixed machine/power converter systems.”
