数字化变电站越来越多地采用以太网技术，针对各种保护和控制IED（Integrated Drive Electronics）的参数配置以及状态监测问题，本文通过对Linux平台上的BOA服务器和CGIC的源码进行研究和修改，设计了一种实用的嵌入式web服务器。它可方便地在支持TCP／IP协议的非Linux的嵌入式系统上运行，在不影响IED原有功能的前提下对用户提供Web服务，同时提出了一种适合嵌入式系统使用的访问权限认证和对Web页面的管理及动态生成机制，并支持Web方式下文件的上传与下载。它为变电站现场嵌入式IED的远端访问与控制提供了一种新的思路和方法。

The digital substation using more and more Ethernet technologies, With the problems of all kinds of protection and of controling IED＇s configuration and monitoring condition, the paper researches and modifies BOA server and CGIC＇s source code based on Linux, designs an embedded Web server . It can operate convinently in non-Linux embedded system which supports the TCP/IP proto col. The design doesn＇t affect original function of IED and can provide Web service to users. The paper proposes a certification for access authority and manages the Web page and dynamic generation. It also supports the upload and download of the file based on Web. For remote access and control of the substation site embedded IED, it proposes a new idea and method.
