【正文】 clude generator protection, main transformer protection and start up/stand by transformer protection. Automatic devices include automatic regulator voltage (AVR),automatic transfer switch(ATS) ,faultkymograp hand protection includes highvoltage motor lowvoltage system includes autolowvoltage intelligent motor protector ,breaker , DC system , etc [ 2 ]water system are not included. The characteristics of electrical system [ 3 ]operation frequency than thermal microputer and largeadopted. mainly on steam9electrical system.“Hardcable”.exchange is limited on account of the cost .impossible to acplish more plex electrical data. Aiming at the paratively laggard level of power plant electrical system automation, this paper analyzes the feasibility, necessity and some key points of the application of integrated automation technology to power plant electrical system. New idea using fieldbus control system technology is presented. This paper also gives the outline and detailed antomatic synchronization system (ASS) . 6 kV auxiliary power integrative protection device, auxiliary transformer integrative protection device, feeder protection device, etc. 400 V changeover device, intelligent. All these belong to the electrical system. The mon systems such as coalhandling system, ash handling system and chemical are that electrical equipments have less control objects。后來，越來越多的電廠特別是那些新建的電廠熱忠于電氣綜合自動(dòng)化系統(tǒng)而不是傳統(tǒng)的集散控制系統(tǒng)。這些標(biāo)準(zhǔn)都是很有影響的現(xiàn)場總線技術(shù)，而且在工業(yè)自動(dòng)化領(lǐng)域有廣泛的應(yīng)用。由于保護(hù)和自動(dòng)裝置由不同的廠家生產(chǎn)，所以其物理上的層和通信協(xié)議可能會(huì)有所差異，這樣就使得設(shè)備之間不可能被簡單的聯(lián)系起來。 4 總 結(jié) 采用電力系統(tǒng)綜合自動(dòng)化是提高電廠自動(dòng)化水平的趨勢，特別是改善電廠的管理水平。這篇論文提出了電氣系統(tǒng)綜合自動(dòng)化兩個(gè)系統(tǒng)的問題。根據(jù)電力系統(tǒng)的功能這些子系統(tǒng)被分為 6 千伏子系統(tǒng)， 400 伏子系統(tǒng)，變壓器保護(hù)子系統(tǒng)和 AVR 子系統(tǒng)等等。 以微型計(jì)算機(jī)為基礎(chǔ)的電氣系統(tǒng)，現(xiàn)場總線系統(tǒng)或者以太網(wǎng)絡(luò)技術(shù)的應(yīng)用程序和通信功能由給發(fā)電廠綜合自動(dòng)化提供支持的集散控制系統(tǒng)提供。 以微型計(jì)算機(jī)為基礎(chǔ)的保護(hù)和 自動(dòng)化設(shè)備被廣泛地應(yīng)用在電廠電氣系統(tǒng)中。 the other is how to connect electrical system with DCS. Fieldbus standard is the main problem in buildin
