單元機組控制系統(tǒng)一體化的崛起
　　隨著一些電廠將電氣發(fā)變組和廠用電系統(tǒng)的控制(ECS)功能納入DCS的SCS控制功能范圍，ETS控制功能改由DCS模件構(gòu)成，DEH與DCS的軟硬件合二為一，以及一些機組的煙氣濕法脫硫控制直接進入單元機組DCS控制的成功運行，標志著控制系統(tǒng)一體化，在DCS技術(shù)的發(fā)展推動下而走向成熟。
　　由于一體化減少了信號間的連接接口以及因接口及線路異常帶來的傳遞過程故障，減少了備品備件的品種和數(shù)量，降低了維護的工作量及費用，所以近幾年一體化控制系統(tǒng)在不同容量的新建機組中逐漸得到應(yīng)用，如浙江華能玉環(huán)電廠4×1000MW機組、臺州電廠2×300MW機組和安徽鳳臺電廠4×600MW機組均全廠采用西屋Ovation系統(tǒng)，國華浙能寧海電廠4×600MW機組全廠采用西門子公司的T-XP系統(tǒng)，大唐烏沙山電廠4×600MW機組全廠采用I/A系統(tǒng)，國華臺山電廠2×1000MW機組采用北京和利時公司系統(tǒng)，浙江樂清電廠4×600MW機組全廠采用ABB公司的SYMPHONY系統(tǒng)等。 控制系統(tǒng)一體化的實現(xiàn)，是電力行業(yè)DCS應(yīng)用功能快速發(fā)展的體現(xiàn)。排除人為因素外，控制系統(tǒng)一體化將為越來越多的電廠所采用。
　　3)DCS結(jié)構(gòu)變化，應(yīng)用技術(shù)得到快速發(fā)展
　　隨著電子技術(shù)的發(fā)展，近年來DCS系統(tǒng)在結(jié)構(gòu)上發(fā)生變化。過去強調(diào)的是控制功能盡可能分散，由此帶來的是使用過多的控制器和接口間連接。但過多的控制器和接口間連接，不一定能提高系統(tǒng)運行可靠性，相反倒有可能導(dǎo)致故障停機的概率增加。何況單元機組各個控制系統(tǒng)間的信號聯(lián)系千絲萬縷，互相牽連，一對控制器故障就可能導(dǎo)致機組停機，即使沒有直接導(dǎo)致停機，也會影響其它控制器因失去正確的信號而不能正常工作。
　　因此隨之控制器功能與容量的成倍增加、更多安全措施(包括采用安全性控制器)、冗余技術(shù)的采用(有的DCS的核心部件CPU，采用2×2冗余方式)以及速度與可靠性的提高，目前DCS正在轉(zhuǎn)向適度集中，將相互聯(lián)系密切的多個控制系統(tǒng)和非常復(fù)雜的控制功能集中在一對控制器中，以及上述所說的單元機組采用一體化控制系統(tǒng)，正成為DCS應(yīng)用技術(shù)發(fā)展的新方向，這不但減少了故障環(huán)節(jié)，還因內(nèi)部信息交換方便和信息傳遞途徑的減少而提高了可靠性。
　　此外，隨著近幾年DCS應(yīng)用技術(shù)的發(fā)展，如采用通用化的硬件平臺，獨立的應(yīng)用體系，標準化的通訊協(xié)議，PLC控制器額融入，F(xiàn)CS功能的實現(xiàn)，一鍵啟動技術(shù)的成功應(yīng)用等，都為DCS增添了新的活力，功能進一步提高，應(yīng)用范圍更加寬廣。
　　4)全廠輔控系統(tǒng)走向集中監(jiān)控
　　一個火電廠有10多個輔助車間，國內(nèi)過去通常都是由PLC和上位機構(gòu)成各自的網(wǎng)絡(luò)，在各車間控制室內(nèi)單獨控制，因此得配備大量的運行人員。為了提高外圍設(shè)備控制水平和勞動生產(chǎn)率，達到減員增效的目的，隨著DCS技術(shù)和網(wǎng)絡(luò)通訊功能的提高，目前各個輔助車間的控制已趨向適度集中，
　　整合成一個輔控網(wǎng)(簡稱BOP 即Balance Of Plant的縮寫)方向發(fā)展，即將相互獨立的各個外圍輔助系統(tǒng)，利用計算機及網(wǎng)絡(luò)技術(shù)進行集成，在全廠IT系統(tǒng)上進行運行狀況監(jiān)控，實現(xiàn)外圍控制少人值班或無人值班。
　　近幾年新建工程迅速向這個方向發(fā)展。如國華浙能寧海電廠一期工程(4×600MW)燃煤機組BOP覆蓋了水、煤、灰等共13個輔助車間子系統(tǒng)的監(jiān)控，下設(shè)水、煤、灰三個監(jiān)控點，集中監(jiān)控點設(shè)在四機一控室里，打破了傳統(tǒng)的全廠輔助車間運行管理模式，不但比常規(guī)減員30%，還提升了全廠運行管理水平。整個輔控網(wǎng)的硬件和軟件的統(tǒng)一，減少了庫存?zhèn)淦穫浼叭粘９芾砭S護費用。由于取消了多個就地控制室，使得基建費用和今后的維護費用都減少。一些老廠的輔助車間也在進行BOP改造，其中浙江省第一家完成改造的是嘉興發(fā)電廠2×300MW機組，取得較好效果。
