摘要：变电站综合自动化是指利用先进的计算机技术、现代电子技术、通信技术和信号处理技术，实现对变电站主要设备和输、配电线路的自动监视、测量、控制、保护以及与调度通信等综合性自动化功能。近年来，随着国民经济的快速增长，传统的变电站已经远远不能满足现代电力系统管理模式的需求。因此，将变电站由常规站改造为综自站已渐渐成为一种趋势。该文就综自改造中出现的问题做出相应分析，以寻找解决这些问题的合理方案。

Abstract: substation integrated automation is the use of advanced computer technology, modern electronic technology, communication technology and signal processing technology, the implementation of substation main equipment and transport, distribution circuit of automatic monitoring, measurement, control, protection and communication and dispatching integrated automation function. In recent years, with the rapid growth of national economy, the traditional substation has far cannot satisfy the needs of modern management mode of power system. Therefore, transformed substation by routine for all the standing has gradually become a trend. This article all the problems arising from the modification accordingly analysis, to find reasonable solutions to these problems.    关键词：综合自动化 原则 事故信号 GPS 后台监控   Key words: integrated automation principle of GPS signal background monitor accident    0 引言   0 the introduction    近年来，将变电站由常规站改为综自站渐渐成为一种趋势。综自改造后的变电站，其运行情况越来越依赖于自动化装置的实用性及成熟性。   In recent years, the substation from conventional station to ensemble since gradually become a trend. Zong since after transforming the substation, its operation is more and more depends on the practicability of automation devices and maturity.    1 自动化改造的原则　   The principle of 1 automation reconstruction    将一次设备在线监测系统与变电站自动化系统集成，可以提高高压电气设备的运行可靠性，且有望实现真正意义上的变电站无人值班；继续提高二次设备的智能化水平，引入PLC技术，实现变电站从多人值班到少人值班、从少人值班到无人值班有人巡视的平稳过渡；引入先进的WEBServer技术和防火墙技术，使运行管理人员可通过Internet/Intranet实现远程访问和维护；结合通信工程，综合考虑变电站的调度通道问题。   Will a equipment online monitoring system and substation integrated automation system, can improve the operation reliability of the high voltage electrical equipment, and to realize the true sense of the unattended substation; Continue to improve intelligent level of secondary equipment, introduced the PLC technology, substation from the people on duty to less people, someone from less person on duty to unmanned on duty patrol a smooth transition; The introduction of advanced WEBServer technology and firewall technology, make the operation and management personnel can through the Internet/Intranet to realize remote access and maintenance; Communication engineering, comprehensive consideration of substation dispatching channel problem.
