描述电力驱动器中所有组件的高频行为的仿真模型的开发可以被认为是一个非常有用的工具。这些模型的用途超出了对驱动元件引起的干扰（过电压、轴承电流、EMI 等）的描述。从这些模型中，可以评估系统元素对扰动的影响。本文提出了一个完整的模型，由代表每个驱动元件的简单结构组成：电机供电电缆、接地系统、电机、电子转换器和电源线。完整的系统模型允许开发考虑所有扰动的缓解技术。此外，所提出的方法允许计算从转换器进行的测试中得出的不同系统参数的值。结果表明，该模型足以准确地描述高频驱动行为。
The development of simulation models that describe the high-frequency behaviour of all the components in an electrical drive, can be considered as a very useful tool. The usefulness of these models exceeds the description of the disturbances caused by the drive elements (overvoltages, bearing currents, EMI, etc.). From these models, the influence of the system elements on the disturbances can be evaluated. This paper proposes a complete model consisting of simple structures representing every drive element: motor supply cable, ground system, electrical machine, electronic converter and power line. A complete system model allows the development of mitigation techniques that take into account all the perturbations. In addition, the proposed methodology allows calculating values for the different system parameters derived from tests carried out with the converter. The results show that the model is accurate enough to describe the high-frequency drive behaviour.
