嵌入式系统在变电站安全通信系统中的研究

Research on Embedded Technology in a Substation Automation Security Communication System

变电站自动化系统在应用IEC61850国际统一标准后,如何采用安全的嵌入式技术,使其能在变电站与控制系统之间进行安全地通信,是目前关于变电站安全通信研究中的一个热点。在分析了嵌入式技术应用于IEC61850标准的变电站内通信系统可行性的基础上,增加了可信计算平台(TPM)的嵌入设计,使得该嵌入式系统成为一种面向应用、安全的操作系统。

This paper describes the embedded technology in the structure of substation automation system.The structure of substation automation information system is based on IEC 61850 architecture.The security communication system of substation automation information is brought forward based on TPM（ Trusted Computing Platform）,which indicates the direction of development of secure computing system.This computation module is integrated into lED of substation,so as to authentication of identity and information integrality is implemented in process of information exchange between lED and control center,
