摘  要

 變電站綜合自動(dòng)化系統(tǒng)是在變電站應(yīng)用自動(dòng)控制技術(shù)和信息處理與傳輸技術(shù)，通過(guò)計(jì)算機(jī)硬件系統(tǒng)或自動(dòng)化裝置代替人工進(jìn)行各種運(yùn)行作業(yè)，提高變電站運(yùn)行、管理水平的一種自動(dòng)化，通過(guò)變電站綜合自動(dòng)化系統(tǒng)內(nèi)各設(shè)備間相互交換信息、數(shù)據(jù)共享，完成變電站運(yùn)行監(jiān)視和控制任務(wù)。變電站綜合自動(dòng)化系統(tǒng)是提高變電站安全穩(wěn)定運(yùn)行水平、降低運(yùn)行維護(hù)成本、提高經(jīng)濟(jì)效益、向用戶提供高質(zhì)量電能的一項(xiàng)重要技術(shù)措施。功能的綜合是其區(qū)別于常規(guī)變電站的最大特點(diǎn),它以計(jì)算機(jī)技術(shù)為基礎(chǔ), 以數(shù)據(jù)通訊為手段,以信息共享為目標(biāo)，通過(guò)將變電站原有的保護(hù)、儀表、中央信號(hào)、遠(yuǎn)動(dòng)裝置等二次系統(tǒng)及功能重新組合、互聯(lián)和計(jì)算機(jī)化，集變電站保護(hù)、測(cè)量、監(jiān)視和遠(yuǎn)方控制于一體，完全替代了變電站常規(guī)二次設(shè)備，簡(jiǎn)化了變電站二次接線。變電站綜合自動(dòng)化具有以下優(yōu)越性：(1)提高供電質(zhì)量，提高電壓合格率。(2)提高變電站的安全、可靠運(yùn)行水平。(3)提高電力系統(tǒng)的運(yùn)行、管理水平。(4)縮小變電站占地面積，降低造價(jià)，減少總投資。(5)減少維護(hù)工作量，減少值班員勞動(dòng)，實(shí)現(xiàn)減人增效。

Abstract
 Substation integrated automation system in substation application automatic control and information processing and transmission technology, through the computer hardware system instead of manual or automatic device of operation, improve the management level of substation operation,  through automation, substation automation system devices in the mutual exchange of information, data sharing, the completion of substation operation monitoring and control task. Substation integrated automation system is to improve the level of safe and stable operation, reduce operation and maintenance costs, improve economic efficiency to provide users with high-quality power is an important technical measure. Function integrated is its biggest characteristics is different from conventional substation, it is based on computer technology, In data communications as a means, to information sharing as the goal, through the transformer substation the original protection, instrumentation, central signal, remote devices such as the two times system and function of recombined, Internet and computer, set of substation protection, measurement, monitoring and remote control in one, completely replace the conventional substation two equipment, simplifying the the two wiring of transformer substation. Integrated substation automation system has the following advantages: (1) improve the quality of power supply, improve the voltage qualification rate. (2) the improvement of safety, reliable operation level. (3)  improve the operation of power system, the management level.  (4) narrowing of substation area, reduce cost, reduce the total investment.(5) reduce the maintenance workload, reduce the attendant labor, implementation decreases person synergism.

Key words: automatic control technology; information processing; data sharing
