摘要：變電站綜合自動(dòng)化是指利用先進(jìn)的計(jì)算機(jī)技術(shù)、現(xiàn)代電子技術(shù)、通信技術(shù)和信號(hào)處理技術(shù)，實(shí)現(xiàn)對(duì)變電站主要設(shè)備和輸、配電線路的自動(dòng)監(jiān)視、測(cè)量、控制、保護(hù)以及與調(diào)度通信等綜合性自動(dòng)化功能。近年來，隨著國民經(jīng)濟(jì)的快速增長，傳統(tǒng)的變電站已經(jīng)遠(yuǎn)遠(yuǎn)不能滿足現(xiàn)代電力系統(tǒng)管理模式的需求。因此，將變電站由常規(guī)站改造為綜自站已漸漸成為一種趨勢(shì)。該文就綜自改造中出現(xiàn)的問題做出相應(yīng)分析，以尋找解決這些問題的合理方案。

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.    關(guān)鍵詞：綜合自動(dòng)化 原則 事故信號(hào) GPS 后臺(tái)監(jiān)控   Key words: integrated automation principle of GPS signal background monitor accident    0 引言   0 the introduction    近年來，將變電站由常規(guī)站改為綜自站漸漸成為一種趨勢(shì)。綜自改造后的變電站，其運(yùn)行情況越來越依賴于自動(dòng)化裝置的實(shí)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 自動(dòng)化改造的原則　   The principle of 1 automation reconstruction    將一次設(shè)備在線監(jiān)測(cè)系統(tǒng)與變電站自動(dòng)化系統(tǒng)集成，可以提高高壓電氣設(shè)備的運(yùn)行可靠性，且有望實(shí)現(xiàn)真正意義上的變電站無人值班；繼續(xù)提高二次設(shè)備的智能化水平，引入PLC技術(shù)，實(shí)現(xiàn)變電站從多人值班到少人值班、從少人值班到無人值班有人巡視的平穩(wěn)過渡；引入先進(jìn)的WEBServer技術(shù)和防火墻技術(shù)，使運(yùn)行管理人員可通過Internet/Intranet實(shí)現(xiàn)遠(yuǎn)程訪問和維護(hù)；結(jié)合通信工程，綜合考慮變電站的調(diào)度通道問題。   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.
