感应电机（IM）是工业上普遍采用的一种电机，它在机械与电力之间的能量转换中起着重要的作用。本文提出了一种基于电力电子变换器的IM电源半在环仿真器，该仿真器可以模拟具有内部故障的IM。可以减少与产生实际故障相关的风险、时间和成本，帮助克服实际故障机器的安全问题。该技术还可应用于故障检测、诊断和故障控制等领域。首先，建立了考虑定子绕组匝间短路的IM数学模型。在此基础上，开发了PHIL仿真器，并对IM的不同匝间短路情况进行了测试。仿真结果与仿真结果和实际IM结果的比较验证了该方案的有效性。
The induction machine (IM) is commonly adopted in the industry, which plays an important role in energy conversion between mechanical and electrical power. This article proposes a power electronic converter based IM power hardware-in-the-loop (PHIL) emulator, which can emulate an IM with internal faults. The risk, time, and cost associated with generating real faults can be reduced, helping to overcome safety issues with actual faulted machines. The technique could also be applied in fault detection, diagnosis, and fault control areas. First, the IM mathematical model with an interturn short circuit of the stator winding is established. Based on that, the PHIL emulator is developed and tested for different interturn short-circuit conditions of an IM. A comparison of the emulator results with simulation results and actual IM results demonstrates the validity of the proposed solution.
