在本文中，提出了一种方法，用于消除与新的驱动系统拓扑结构，原型电机，先进的控制系统策略，或上述组合的测试和开发相关的风险，而不使用任何真实的电动机/发电机。低功率机器的测试平台相对便宜且易于使用;然而，随着功率水平增加到上千瓦和兆瓦范围，原型机器和驱动器的验证变得昂贵。所提出的感应电机仿真器（IME）平台利用功率硬件在环概念，结合高保真机器模型和负载动态。电机及其负载动态特性通过实时数字仿真器进行仿真，该仿真器为基于电力电子的电压放大器生成适当的控制命令，该电压放大器与变速驱动器（VSD）接口。具体而言，通过改变经由独特的基于变压器的LCL型耦合网络连接到被测VSD的电压放大器的相位和幅度来重新创建电流消耗。基于所提出的概念，使用多绕组分接变换Transformer建立了一个真正通用的测试平台，适用于各种功率水平。此外，本文提出了一种在同步旋转坐标系中的dq坐标系的电力电子变换器在IME操作的控制策略。在25-kVA功率水平的实验结果验证了所提出的测试平台的可行性和高动态性能。
In this paper, a method is presented for removing the risk associated with the testing and development of novel drive system topologies, prototype electrical machines, advanced control system strategies, or a combination of the aforementioned without using any real motors/generators. The test platforms for low-power machines are relatively inexpensive and accessible; however, as power levels increase into the upper kilowatt and megawatt range, validation of prototype machines and drives becomes costly. The proposed induction machine emulator (IME) platform utilizes the power hardware-in-the-loop concept in conjunction with a high-fidelity machine model and load dynamics. The electrical machine and its load dynamics are simulated with a real-time digital simulator, which generates appropriate control commands to a power electronics-based voltage amplifier that interfaces to a variable speed drive (VSD). Specifically, the current draw is recreated by altering the phase and magnitude of a voltage amplifier connected to a VSD under test via a unique transformer-based LCL-type coupling network. Based on the proposed concept, the use of a multiwinding, tap-changing transformer establishes a truly versatile and universal test platform for a wide range of power levels. In addition, this paper presents a control strategy in the synchronously rotating reference frame in dq coordinates for the power electronic converters in IME operation. Experimental results at the 25-kVA power level validate the feasibility and highly dynamic performance of the proposed test platform.
