变频驱动器（VFD）完全改变了连接电机的功率条件和效率。由于数据不足，EnergyPlus等能源模拟程序通过忽略VFD影响直接使用制造商的效率数据。本文旨在验证一种利用等效电路法将制造效率数据转换为VFDs电机实际效率的方法。首先，根据制造商数据估计电机电路参数；然后用VFDs对电机效率进行了仿真，并通过实测效率进行了验证。结果表明，该方法能有效地利用制造数据计算变频调速电机的效率。 引用:2019年年度会议，密苏里州堪萨斯城，扩展摘要

Variable frequency drives (VFDs) completely change the power conditions and efficiency of connected motors. Due to insufficient data, energy simulation programs, such as EnergyPlus, directly use manufacturer efficiency data by ignoring VFD impacts. The paper is to validate an approach to convert manufacture efficiency data to actual motor efficiency with VFDs using the equivalent circuit method. First the motor circuit parameters are estimated based on manufacturer data; and then applied to simulate the motor efficiency with VFDs, which is validated by the measured efficiency. The result shows the approach can effectively calculate the motor efficiency with VFDs using manufacture data.
