描述
多年來(lái),我國(guó)DCS系統(tǒng)市場(chǎng)的基本格局是國(guó)產(chǎn)DCS系統(tǒng)在中小工程項(xiàng)目市場(chǎng)與國(guó)外DCS系統(tǒng)競(jìng)爭(zhēng),而重大工程項(xiàng)目市場(chǎng)幾乎被國(guó)外DCS系統(tǒng)壟斷。這幾年,在中小工程項(xiàng)目市場(chǎng)上,國(guó)產(chǎn)DCS系統(tǒng)以更高的性能價(jià)格比逐漸占有優(yōu)勢(shì)。例如,現(xiàn)在一套國(guó)產(chǎn)300MW火電機(jī)組的DCS系統(tǒng)價(jià)格只是上世紀(jì)80年代國(guó)外DCS系統(tǒng)價(jià)格的三分之一,而控制的功能則大大提高。由于利潤(rùn)空間的大幅度減小,有些國(guó)外DCS系統(tǒng)已經(jīng)逐步從中小項(xiàng)目市場(chǎng)中退出。近幾年國(guó)產(chǎn)DCS系統(tǒng)的銷售額已經(jīng)占市場(chǎng)總銷售額的30%以上,工程項(xiàng)目數(shù)則超過(guò)50%。
最近,國(guó)產(chǎn)DCS系統(tǒng)在重大工程項(xiàng)目領(lǐng)域的突破,打破了原有的市場(chǎng)格局,標(biāo)志著將與國(guó)外DCS系統(tǒng)進(jìn)行“平等”的競(jìng)爭(zhēng)。在這場(chǎng)“戰(zhàn)役”中,國(guó)產(chǎn)DCS系統(tǒng)能否繼續(xù)擴(kuò)大戰(zhàn)果,取得像中小工程項(xiàng)目市場(chǎng)一樣的業(yè)績(jī),引起了業(yè)界充分的關(guān)注。同時(shí),進(jìn)入大型工程項(xiàng)目市場(chǎng)后,國(guó)產(chǎn)DCS系統(tǒng)還有哪些值得注意的問(wèn)題,也是大家思考的問(wèn)題。
根據(jù)自動(dòng)化行業(yè)品牌研究室進(jìn)行各個(gè)方面的調(diào)查和統(tǒng)計(jì)表明,相對(duì)于和利DCS來(lái)說(shuō),中控(SUPCON)DCS相對(duì)比較簡(jiǎn)單適用性更強(qiáng),在穩(wěn)定性和適用性方面有更出色的優(yōu)勢(shì)而且在在軟件組態(tài)方面和系統(tǒng)兼容性方面中控也有很明顯的優(yōu)勢(shì),中控(SUPCON)成為國(guó)內(nèi)DCS用戶的首選之一。
