【正文】 ofmicroputer9basedintegratedautomation technology to power plant electrical system, and gives concrete realization of the program. 2 The status of power plant electrical system The electrical system discussed in this paper is mainly referred to the protection , measurement ,control and automatic devices of secondary system. Main protection devices include 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。與集中的技術(shù)相比較這種技術(shù)有許多的優(yōu)點，比如：它有簡單和柔韌的結(jié)構(gòu)，高的可靠性，方便的安裝和較低的成本。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化系統(tǒng)而不是傳統(tǒng)的集散控制系統(tǒng)。并且，所有這些設(shè)備都具有通信界面，能夠和主系統(tǒng)或其他系統(tǒng)之間通
