| 摘 要： | 从二端口网络分析出发,设计一种基于差分方式的在线阻抗测试方法。运用人工神经网络的优化方法,提出一种阻抗等效电路参数的提取算法,由此建立在线阻抗等效电路模型。应用该方法实现了电力电子设备阻抗的在线工程测量,实测与仿真结果表明基于该建模方法所获得的阻抗等效电路能准确反映设备在线运行的阻抗特征。

| Abstract: | A difference based measurement method of the online impedance in equipment is formulated with the method of two-port electric network analysis.The extraction algorithm for the parameters of the impedance equivalent circuit is proposed with Hopfield artificial neural networks,which helps to formulate the online impedance equivalent circuit model.This method is also applied to measure the online impedance of the electric power and electronic equipment in ship.The testing and simulation results show that the impedance equivalent circuit model based on the proposed method could exactly reflect the impedance characteristic of online running. |
