單元機(jī)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(jī)組的煙氣濕法脫硫控制直接進(jìn)入單元機(jī)組DCS控制的成功運(yùn)行，標(biāo)志著控制系統(tǒng)一體化，在DCS技術(shù)的發(fā)展推動(dòng)下而走向成熟。
　　由于一體化減少了信號(hào)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(hù)的工作量及費(fèi)用，所以近幾年一體化控制系統(tǒng)在不同容量的新建機(jī)組中逐漸得到應(yīng)用，如浙江華能玉環(huán)電廠4×1000MW機(jī)組、臺(tái)州電廠2×300MW機(jī)組和安徽鳳臺(tái)電廠4×600MW機(jī)組均全廠采用西屋Ovation系統(tǒng)，國(guó)華浙能寧海電廠4×600MW機(jī)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(jī)組全廠采用I/A系統(tǒng)，國(guó)華臺(tái)山電廠2×1000MW機(jī)組采用北京和利時(shí)公司系統(tǒng)，浙江樂清電廠4×600MW機(jī)組全廠采用ABB公司的SYMPHONY系統(tǒng)等。 控制系統(tǒng)一體化的實(shí)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(qiáng)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(yùn)行可靠性，相反倒有可能導(dǎo)致故障停機(jī)的概率增加。何況單元機(jī)組各個(gè)控制系統(tǒng)間的信號(hào)聯(lián)系千絲萬(wàn)縷，互相牽連，一對(duì)控制器故障就可能導(dǎo)致機(jī)組停機(jī)，即使沒有直接導(dǎo)致停機(jī)，也會(huì)影響其它控制器因失去正確的信號(hào)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(gè)控制系統(tǒng)和非常復(fù)雜的控制功能集中在一對(duì)控制器中，以及上述所說的單元機(jī)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(tái)，獨(dú)立的應(yīng)用體系，標(biāo)準(zhǔn)化的通訊協(xié)議，PLC控制器額融入，F(xiàn)CS功能的實(shí)現(xiàn)，一鍵啟動(dòng)技術(shù)的成功應(yīng)用等，都為DCS增添了新的活力，功能進(jìn)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(gè)火電廠有10多個(gè)輔助車間，國(guó)內(nèi)過去通常都是由PLC和上位機(jī)構(gòu)成各自的網(wǎng)絡(luò)，在各車間控制室內(nèi)單獨(dú)控制，因此得配備大量的運(yùn)行人員。為了提高外圍設(shè)備控制水平和勞動(dòng)生產(chǎn)率，達(dá)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(gè)輔助車間的控制已趨向適度集中，
　　整合成一個(gè)輔控網(wǎng)(簡(jiǎn)稱BOP 即Balance Of Plant的縮寫)方向發(fā)展，即將相互獨(dú)立的各個(gè)外圍輔助系統(tǒng)，利用計(jì)算機(jī)及網(wǎng)絡(luò)技術(shù)進(jìn)行集成，在全廠IT系統(tǒng)上進(jìn)行運(yùn)行狀況監(jiān)控，實(shí)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(gè)方向發(fā)展。如國(guó)華浙能寧海電廠一期工程(4×600MW)燃煤機(jī)組BOP覆蓋了水、煤、灰等共13個(gè)輔助車間子系統(tǒng)的監(jiān)控，下設(shè)水、煤、灰三個(gè)監(jiān)控點(diǎn)，集中監(jiān)控點(diǎn)設(shè)在四機(jī)一控室里，打破了傳統(tǒng)的全廠輔助車間運(yùn)行管理模式，不但比常規(guī)減員30%，還提升了全廠運(yùn)行管理水平。整個(gè)輔控網(wǎng)的硬件和軟件的統(tǒng)一，減少了庫(kù)存?zhèn)淦穫浼�及日常管理維護(hù)費(fèi)用。由于取消了多個(gè)就地控制室，使得基建費(fèi)用和今后的維護(hù)費(fèi)用都減少。一些老廠的輔助車間也在進(jìn)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(jī)組，取得較好效果。
