國(guó)產(chǎn)DCS競(jìng)爭(zhēng)優(yōu)勢(shì)明顯
HVE04.2-W075L目前，已投運(yùn)的國(guó)產(chǎn)DCS系統(tǒng)與進(jìn)口產(chǎn)品比較綜合性能差距不大，各類全封閉設(shè)計(jì)模件具有免維護(hù)性能，總的I/O點(diǎn)數(shù)應(yīng)用也達(dá)到15000多點(diǎn)以上；軟件全在WINDOWS平臺(tái)運(yùn)行，界面友好，組態(tài)修改方便，全中文環(huán)境，易與理解和掌握，應(yīng)用功能基本包括了電廠的全部需求。這表明DCS設(shè)計(jì)制造、性能參數(shù)方面均能滿足當(dāng)前我國(guó)火電機(jī)組建設(shè)設(shè)計(jì)規(guī)范要求。“從我們的調(diào)研數(shù)據(jù)可以看出，經(jīng)過(guò)近幾年持續(xù)的對(duì)進(jìn)口DCS系統(tǒng)的消化吸收、自身研發(fā)與努力，國(guó)產(chǎn)分散控制系統(tǒng)已取得了長(zhǎng)足的進(jìn)步與發(fā)展。特別是在幾大發(fā)電集團(tuán)的支持下，國(guó)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?！闭憬‰娏倦娏茖W(xué)研究副總工程師朱北恒說(shuō)。
HVE04.2-W075L相比進(jìn)口DCS而言，國(guó)產(chǎn)DCS更容易實(shí)現(xiàn)一體化。如國(guó)電智深EDPF-NT系統(tǒng)在莊河電廠的成功應(yīng)用，代表國(guó)內(nèi)DCS產(chǎn)業(yè)打破了國(guó)外產(chǎn)品在國(guó)內(nèi)自動(dòng)化控制高端領(lǐng)域的壟斷，已成功實(shí)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(hù)統(tǒng)一、方便的優(yōu)點(diǎn)。在價(jià)格方面，國(guó)產(chǎn)DCS打破了進(jìn)口DCS對(duì)市場(chǎng)的壟斷局面，降低了投資成本?！皬氖袌?chǎng)情況看，目前國(guó)產(chǎn)控制系統(tǒng)設(shè)備建設(shè)投資比進(jìn)口設(shè)備仍低50%左右?！彪娏π袠I(yè)熱工自動(dòng)化技術(shù)委員會(huì)副秘書(shū)長(zhǎng)孫長(zhǎng)生說(shuō)。
從DCS廠家的售后服務(wù)看，進(jìn)口DCS產(chǎn)品采用大幅度提高備品備件價(jià)格和售后服務(wù)費(fèi)用的策略，來(lái)挽回工程投標(biāo)價(jià)降低帶來(lái)的利潤(rùn)減少。而國(guó)產(chǎn)DCS廠家的服務(wù)態(tài)度和到位及時(shí)性都明顯要高于進(jìn)口DCS，服務(wù)費(fèi)用也大大低于進(jìn)口DCS。在備品、備件供貨周期，現(xiàn)場(chǎng)服務(wù)等待時(shí)間以及年均設(shè)備更換費(fèi)用、質(zhì)保服務(wù)費(fèi)用方面和進(jìn)口品牌相比都具有明顯的地域優(yōu)勢(shì)和價(jià)格優(yōu)勢(shì)?？傮w運(yùn)行維護(hù)費(fèi)用大約為國(guó)外品牌的1/3左右。
主機(jī)上的應(yīng)用還并非主力
HVE04.2-W075L雖然國(guó)產(chǎn)DCS具有價(jià)格優(yōu)勢(shì)、易擴(kuò)展且擴(kuò)展成本低、能夠?qū)崿F(xiàn)減人增效，并有助于取代進(jìn)口DCS。但目前60萬(wàn)千瓦以上機(jī)組的DCS基本仍以進(jìn)口產(chǎn)品主流。據(jù)孫長(zhǎng)生的調(diào)研統(tǒng)計(jì)顯示，在主機(jī)上的應(yīng)用情況，進(jìn)口產(chǎn)品與國(guó)內(nèi)產(chǎn)品的比重大約為：30萬(wàn)千瓦機(jī)組為3：1，60萬(wàn)千瓦及以上機(jī)組為14：1，100萬(wàn)千瓦機(jī)組為9：1。
