The simulation of electrostatic coupling intra-body communication based on the finite-element method

In this paper, investigation has been done in the computer simulation of the electrostatic coupling IBC by using the developed finite-element models, in which a.the incidence and reflection of electronic signal in the upper arm model were analyzed by using the theory of electromagnetic wave;b.the finite-element models of electrostatic coupling IBC were developed by using the electromagnetic analysis package of ANSYS software;c.the signal attenuation of electrostatic coupling IBC were simulated under the conditions of different signal frequencies, electrodes directions, electrodes sizes and transmission distances. Finally, some important conclusions are deduced on the basis of simulation results.

复杂系统理论在电力系统中的应用研究展望

国内外电网在过去十多年来曾发生多次由连锁故障导致的大停电事故,引起人们对电网安全的高度重视,促使人们深入研究连锁故障传播机理。近年来,关于复杂系统理论,特别是复杂网络理论的研究取得了重要进展。应用复杂系统理论为分析和研究大停电和连锁故障传播机理提供了一种新的视角,有助于从整体上掌握电力网络的复杂性,并讨论相应的动力学特性。主要从复杂网络、自组织临界性以及电网与通信网络的耦合关系这3个方面对近年来电力系统连锁故障建模以及电网脆弱性分析方面的研究进行综述,并展望相关重要研究课题与方向。
