一、電氣綜合自動化系統(tǒng)的功能

　　根據(jù)單元機(jī)組的運行和電氣控制的特點，應(yīng)將發(fā)電機(jī)一變壓器組和廠用電源等電氣系統(tǒng)的控制都納入ECS監(jiān)控。其基本功能 為：

　　1.發(fā)變組出口220kV/500kV斷路器、隔離開關(guān)的控制及操作。

　　2.發(fā)變組保護(hù)、廠高變保護(hù)、勵磁變壓器保護(hù)控制。

　　3.發(fā)電機(jī)勵磁系統(tǒng)。包括啟勵、滅磁操作，控制方式切換，增磁、減磁操作，PSS(電力系統(tǒng)穩(wěn)定器)的投退。

　　4.220kV/500kV開關(guān)自動同期并網(wǎng)及手動同期并網(wǎng)。

　　5.6kV高壓廠用電源監(jiān)視、操作、廠用電壓快切裝zhidezhuangtai監(jiān)視、投退、手動啟動等。

　　6.380V低壓廠用dianyuanjian視、操作、diyabei自投裝置控制。

　　7.高壓啟/備變壓器控制和操作(2臺機(jī)共用)。

　　8.柴油發(fā)電機(jī)組和保安電源控制和操作。

　　9.直流系統(tǒng)和LPS系統(tǒng)的監(jiān)視。

　　對于發(fā)變組保護(hù)等主保護(hù)和安全自動裝置，因其設(shè)備已經(jīng)很成熟而且要求全部在DCS中實現(xiàn)其功能尚有一定難度，可能增加相當(dāng)大的費用，故可以保留。但是它們與DCS間要口求接，控制采用硬接線，利用通訊方式傳輸自動裝置信息，并可以通過DCS進(jìn)行事故追憶。

　　二、電氣自動化控制系統(tǒng)的設(shè)計思想

　　1.集中監(jiān)控方式

　　這種監(jiān)控方式優(yōu)點是運行維護(hù)方便，控制站的防護(hù)要求不高，系統(tǒng)設(shè)計容易。但由于集中式的主要特點是將系統(tǒng)的各個功能集中到一個處理器進(jìn)行處理，處理器的任務(wù)相當(dāng)繁重，處理速度受到影響。由于電氣設(shè)備全部進(jìn)入監(jiān)控，伴隨著監(jiān)控對象的大量增加隨之而來的是主機(jī)冗余的下降、電纜數(shù)量增加，投資加大，長距離電纜引入的干擾也可能影響系統(tǒng)的可靠性。同時， 隔離刀閘的操作閉鎖和斷路器的聯(lián)鎖采用硬接線，由于隔離刀閘defu助接點經(jīng)常不到位，造成設(shè)備無法操作。這種接線的二次接線復(fù)雜，查線不方便，大大增加了維護(hù)量，還存在由于查線或傳動過程中由于接線復(fù)雜而造成誤操作的可能性。
