基于 PEEC 理论的线缆建模方法

摘要

With the increase of equipment on ships ,the electromagnetic coupling between cables which used for commu‐nication among devices cannot be ignored .PEEC is a complex method of field and circuit .In PEEC ,parameters are extracted from the analysis of field to obtain equivalent circuit .By simulating the circuit ,signal of cables can be calculated accurately and efficiently .In this paper ,the basic principle of PEEC is introduced ,and in order to improve the calculation efficiency and accuracy in PEEC model for cables ,some improvements are made in PEEC method based on the structural characteristics of cables .%随着舰船上设备的增多，用于设备间通信的连接线缆的相互耦合越来越不可忽视。部分元等效电路方法（PEEC）作为一种场路结合的方法，通过场的方法提取等效电路参数，形成等效电路模型，进而进行相应的电路仿真计算。将 PEEC 方法应用于线缆建模，可以准确而高效地提取其等效电路模型，完成线缆的仿真计算。文章简述了 PEEC 方法的基本原理，并针对线缆的结构特点，对基本 PEEC 方法进行了相应的改进使其更加适用于线缆的等效电路建模。
