Abstract
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 amplifica?tion,isolation and other measures are adopted to ensure the experiment on the rails,and the relevant factors are corrected. Lab?VIEW 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.关键词
