隨著計算機軟件、硬件、網(wǎng)絡(luò)技術(shù)的飛速發(fā)展以及發(fā)電機組單機容量的迅速增加，微機局域網(wǎng)絡(luò)的應(yīng)用已是電力監(jiān)控系統(tǒng)發(fā)展的必然趨勢［1，2］。江油發(fā)電廠7號、8號機組為進口法國ALSTHOM公司的330 MW火電機組，其控制設(shè)備Centrolog—T20系統(tǒng)為國外80年代產(chǎn)品，共采集模擬量700個、邏輯量3 000多個，是典型的大型分散控制和集中監(jiān)視系統(tǒng)。其下位機T20系統(tǒng)包括邏輯控制(Controlbloc)、鍋爐控制(Micro—z)、汽機控制(Micro—Rec)等下級控制和調(diào)節(jié)系統(tǒng)，它完成機組主輔機控制和調(diào)節(jié)以及電氣控制。上位機Centrolog系統(tǒng)是以1臺BULL公司的Solar小型機為中心，在RTES16實時操作系統(tǒng)支撐下構(gòu)成的多任務(wù)實時系統(tǒng)，對機組運行狀態(tài)和參數(shù)信息進行集中監(jiān)視。機組多年的運行表明：下位機T20系統(tǒng)具有很高的可靠性，其系統(tǒng)軟、硬件設(shè)計嚴密周到，充分考慮了特殊情況，留有充足的備用資源；上位機Centrolog系統(tǒng)的數(shù)據(jù)有較高的可靠性和準確性。由于機組取消了很多常規(guī)儀表，因而數(shù)據(jù)大多通過Centrolog系統(tǒng)進行監(jiān)測，它具有相當?shù)膶嵱眯?，是不可缺少的重要設(shè)備。然而，Centrolog系統(tǒng)也存在一些問題，給發(fā)電機組的安全運行帶來了較大影響和隱患?；诖?，省電力局組織科研力量于1996年開始對系統(tǒng)進行技術(shù)改造，利用現(xiàn)有的高性能微機取代原小型機，與微機網(wǎng)絡(luò)接軌。
