隨著我國DCS技術(shù)不斷創(chuàng)新研發(fā)，國產(chǎn)DCS企業(yè)的市場競爭力不斷增強，我國DCS系統(tǒng)優(yōu)勢逐漸明顯。
DKC04.3-200-7-FW目前，我國已投運的國產(chǎn)DCS系統(tǒng)與進口產(chǎn)品比較綜合性能距離已拉近，DCS設(shè)計制造、性能參數(shù)方面均能滿足當(dāng)前我國火電機組建設(shè)設(shè)計規(guī)范要求。經(jīng)過近幾年持續(xù)的對進口DCS系統(tǒng)的消化吸收、自身研發(fā)與努力，國產(chǎn)分散控制系統(tǒng)已取得了長足的進步與發(fā)展。特別是在幾大發(fā)電集團的支持下，國產(chǎn)DCS的性能與功能和質(zhì)量可靠性都已得到了快速提升。
DKC04.3-200-7-FW截止去年初，除國電智深EDPF系統(tǒng)6臺100萬千瓦超超臨界機組和30臺60萬千瓦超臨界機組、和利時HOLLYSYS系統(tǒng)應(yīng)用2臺100萬千瓦超超臨界，12臺60萬千瓦亞臨界機組占有了一定比例外，國電南自TCS3000系統(tǒng)、山東魯能LN2000系統(tǒng)、西安熱工院FCS165系統(tǒng)也已進入60萬千瓦機組應(yīng)用，南京科遠(yuǎn)NT6000系統(tǒng)、浙大中控ECS系統(tǒng)和上海新華在XDPS-400基礎(chǔ)上開發(fā)的XDC800系統(tǒng)、上海自動化儀表SUPMAX800在30萬千瓦機組及60萬千瓦機組的輔控系統(tǒng)上也已得到應(yīng)用。系統(tǒng)的硬、軟件運行狀況消除了原先人們的擔(dān)心，機組的熱控自動和保護投入率及動作正確率已經(jīng)達(dá)到進口控制系統(tǒng)同等的檔次。
DKC04.3-200-7-FW目前我國DCS系統(tǒng)具有兩大優(yōu)勢：
一、國產(chǎn)DCS更易實現(xiàn)一體化
國電智深EDPF-NT系統(tǒng)在莊河電廠的成功應(yīng)用，代表國內(nèi)DCS產(chǎn)業(yè)打破了國外產(chǎn)品在國內(nèi)自動化控制高端領(lǐng)域的壟斷，已成功實現(xiàn)主輔控在內(nèi)的一體化DCS，減少不同系統(tǒng)間數(shù)據(jù)通訊及交換，具有生產(chǎn)維護統(tǒng)一、方便的優(yōu)點。在價格方面，國產(chǎn)DCS打破了進口DCS對市場的壟斷局面，降低了投資成本。
二、DKC04.3-200-7-FW售后服務(wù)到位

進口DCS產(chǎn)品采用大幅度提高備品備件價格和售后服務(wù)費用的策略，來挽回工程投標(biāo)價降低帶來的利潤減少。而國產(chǎn)DCS廠家的服務(wù)態(tài)度和到位及時性都明顯要高于進口DCS，服務(wù)費用也大大低于進口DCS。在備品、備件供貨周期，現(xiàn)場服務(wù)等待時間以及年均設(shè)備更換費用、質(zhì)保服務(wù)費用方面和進口品牌相比都具有明顯的地域優(yōu)勢和價格優(yōu)勢?？傮w運行維護費用大約為國外品牌的1/3左右。
