本文介绍了一种在实现中压、大功率、高速异步电动机驱动系统全面测试中起重要作用的实时实功率仿真器的实验研究。仿真器的使用节省了测试成本和时间。包括仿真器的测试台的特征在于连接两个模块化多电平双星斩波单元（DSCC）变换器，所述两个DSCC变换器以前到前的方式连接。本文设计、建造和测试了一个400-${\rm V}_{\rm dc}$、10-kW的小型试验台。它主要由以下两个相同的DSCC变换器组成：1）一个DSCC变换器用作被测逆变器; 2）另一个DSCC变换器用作实时实功率高保真仿真器。实验波形表明，该仿真器能够再现三相200 V、10 kW、四极、9000 r/min异步电动机负载离心压缩机时的电气和机械运行特性。
This paper provides an experimental discussion on a real-time real-power emulator that plays an important role in achieving a total test of medium-voltage, high-power, high-speed induction motor drives. The use of the emulator brings cost and time savings to the test. The test bench including the emulator is characterized by connecting two modular multilevel double-star chopper-cell (DSCC) converters connected in a front-to-front way. This paper designs, builds, and tests a 400-${\rm V}_{\rm dc}$, 10-kW downscaled test bench. It mainly consists of the following two identical DSCC converters: 1) one DSCC converter is used as an inverter under test; and 2) the other as a real-time real-power high-fidelity emulator. Experimental waveforms confirm that the emulator can reproduce electrical and mechanical operating performance of the three-phase 200-V, 10-kW, four-pole, 9000-r/min induction motor loaded with a centrifugal compressor.
