摘要
为了获取平台直流电源网络中各设备在工作状态下的阻抗参数,从而为相关的电力电子工程问题的研究提供依据。论文研究设备处于频率在10kHz以下时阻抗的测量方法。通过向直流电源网络中注入特定频率交流信号并测量其在被测设备产生的电压、电流响应,可以计算该频率下设备的复阻抗值。采取信号放大、隔离等措施保证实验正常进行,并对相关因素进行了校正处理。使用LabVIEW在10kHz以内的阻抗特性曲线。论文采用的方法切实可行,对于直流电源网络设备阻抗频率特性的在线测量与分析具有一定的工程应用价值。
In order to obtain the impedance parameters of each device in the DC power network of the platform, it provides a basis for the research of related power electronic engineering problems.This paper studies the impedance measurement method of the equipment with frequency below 10kHz.The complex impedance of the device can be calculated by injecting a specific frequency AC signal into the DC power network and measuring its voltage and current response generated by the measured device. Signal amplification, isolation and other measures are adopted to ensure the experiment on the rails, and the relevant factors are corrected. LabVIEW is used to control signal generation and data processing. Finally, the impedance characteristic curves of the tested equipment within 10kHz are obtained. The method adopted in this paper is feasible and has certain engineering application value for on-line measurement and analysis of impedance frequency characteristics of DC power network equipment.
