摘要
随着智能电网上升成为国家战略,其高速、高集成度的光纤通信网络通信的安全性和可靠性成为了一个需要重点关注的问题,然而电网中广泛使用的光电信号转换装置却并没有针对可能遭受到的强电磁脉冲攻击进行防护,一旦被干扰或损伤,可能危及整个通信网络乃至电网的安全性。针对一种常用的光电转换器,开展了典型高功率微波环境下的辐照效应试验,发现其在较低场强即可能出现干扰和扰乱的效应现象。并通过进一步的壳体耦合仿真分析和典型半导体器件的干扰机理研究,明确了散热孔阵为主要的能量耦合通道,低频 (L波段)耦合效果优于高频 (S波段)近一个量级。耦合场通过场路耦合主要作用于转换芯片,本质原因可能是半导体器件的闩锁效应。
Abstract
With the smart grid becoming a national strategy,the security and reliability of the high speed and integration optical fiber communication network has become a key problem we need to focus on. But the fiber converter widely used in the power grid has no protection from high power electromagnetic pulse. If it is interfered or damaged, the whole communication network and power grid may be threatened. To study this problem, the thesis presents the test and analysis on a kind of commonly used fiber converter. Through the high power microwave radiation tests, we found the fiber converter might be disturbed or damaged in a low electromagnetic environment. Through further coupling simulation analysis and mechanism study of typical semiconductor device, it is determined that the main energy coupling channel is heat emission holes, and the coupling energy in L band would be at least an order of magnitude greater than that in S band. Coupling energy works mainly on conversion IC chips by field-circuit coupling, and the intrinsic reason might be the latch-up effect of semiconductor devices.
