110kV 数字化变电站计算机监控系统摘要环境气候恶化、能源安全、及电网稳定运行的问题不断突出。变电站是建设智能电网的重要组成部分，为智能电网提供可靠的节点支持。而数字化变电站作为向智能变电站发展的过渡阶段，实现变电站数字化是变电站自动化技术发展必然结果。数字化变电站采用“三层两网”结构，建立全站统一的通信平台，通过高速的光纤网络连接，实现站内设备信息共享。随着计算机技术的不断发展， 利用计算机对变电站的设备进行全方位的监视和操作，实现设备信息的统一采集、存储、传输和处理。本文首先介绍了变电站自动化技术以及及计算机监控系统的发展。然后对数字化变电站及计算机监控系统进行概述，将数字化变电站与综合自动化变电站进行比较，总结数字化变电站的优势及特点。结合实际工程，根据规程规范，着重从二次系统的角度分析如何设计数字化变电站，给出数字化变电站总体方案设计。基于 IEC61850 的三层两网的计算机监控系统的网络结构体系，制定计算机监控系统的组网方案。详细分析数字化变电站信息的流动，完成交换机的配置与端口接线的设计。结合网络部分的二次接线图，详细分析交换机柜原理图以及网络回路图。关键词:数字化变电站，计算机监控系统，网络结构设计，二次接线图 AbstractThe problems of environmental climate deterioration, energy security and stable operation of the grid continue to highlight. Substation is an important part of the construction of smart grid, providing reliable node support for smart grid. As the transition period to the development of intelligent substation, digital substation is the inevitable result of substation automation technology. Digital substation adopts the structure of "three layers and two networks", and establishes a unified communication platform for the whole station. Through high-speed optical fiber network connection, it realizes the sharing of station equipment information. With the development of computer technology, the computer is used to monitor and operate the equipment of the substation in an all-round way, to achieve unified collection, storage, transm...
