摘要
针对电机驱动系统中的强传导干扰超出电磁兼容标准规定限定值且无法定性分析的问题,该文建立了永磁同步电机驱动系统的传导干扰仿真预测模型,将电机驱动系统作为整体的被测设备,由直流侧正负极的人工电源网络输出系统的传导干扰波形,在传导干扰规定的150 kHz^108 MHz范围内进行仿真分析。并在半电波暗室内搭建了电机驱动系统传导干扰实验测试平台,测试系统直流侧正负极传导干扰电压频域波形,将建立的电机驱动系统传导干扰的预测模型所输出的正负极电压频谱图与实验测试图对比,两者整体变化趋势一致,从而验证了电机驱动系统预测模型的正确性和有效性,为进一步分析和研究永磁同步电机控制系统存在的传导干扰奠定了基础。
In view of the problem that the strong conducted interference in the motor-driven system is beyond the limit of EMC standard and cannot be analyzed qualitatively, a simulation and prediction model of conducted interference in the permanent magnet synchronous motor drive system is established. With the motor drive system as the whole tested equipment, the conducted interference waveform of the system is output by the artificial power network of the positive and negative poles at the DC side, and the simulation analysis is carried out within the range of 150 k Hz^108 MHz specified by the conducted interference. In the semi-anechoic chamber, an experimental test platform for conducted interference of the motor-driven system is built to test the frequencydomain waveform of the conducted interference voltage of the positive and negative poles on the DC side of the system. The frequency-domain diagram of the positive and negative pole voltage output from the established prediction model of conducted interference of the motor-driven system is compared with the experimental test diagram and the overall trend of the two is the same so as to verify the validity and validity of the prediction model, which lays a foundation for further analysis and study of conducted disturbances in PMSM control system.
