無(wú)論是新控制系統(tǒng)投運(yùn)還是舊系統(tǒng)改造,DCS控制系統(tǒng)選型一旦確定后,在進(jìn)行系統(tǒng)搭建、硬件測(cè)試和和程序組態(tài)前,必須對(duì)有較強(qiáng)實(shí)踐經(jīng)驗(yàn)的熱控工程師和運(yùn)行操作人員進(jìn)行相關(guān)的培訓(xùn)工作,培訓(xùn)工作必須以仿真機(jī)和實(shí)際系統(tǒng)相結(jié)合,做到有的放矢。
1 對(duì)操作人員的培訓(xùn):由于操作不當(dāng)可能影響DCS硬件或軟件性能,會(huì)間接影響機(jī)組的安全行和經(jīng)濟(jì)指標(biāo),所以在DCS做畫(huà)面過(guò)程中要廣泛征求運(yùn)行人員的意見(jiàn),讓他們參與熟悉設(shè)計(jì)和調(diào)試,以讓他們充分熟悉控制界面(畫(huà)面)的操作變化,知道如何操作。對(duì)啟停設(shè)備、手/自動(dòng)切換等日常性操作和事故情況下的事故干預(yù),應(yīng)編制完整的操作規(guī)程,進(jìn)行技術(shù)培訓(xùn)和演練,要充分利用DCS控制系統(tǒng)調(diào)試階段對(duì)相關(guān)運(yùn)行人員進(jìn)行全面培訓(xùn)。
2 對(duì)熱控人員的培訓(xùn):對(duì)熱控人員的培訓(xùn)要注意各有所長(zhǎng),由于現(xiàn)代DCS控制系統(tǒng)涉及的知識(shí)面很廣,要短時(shí)間進(jìn)行全面掌握是不可能的。所以要充分考慮熱控人員文化素質(zhì)和業(yè)務(wù)水平的差異,優(yōu)先對(duì)多位熱控6、工程師進(jìn)行不同方面的比較深入的培訓(xùn)。通過(guò)培訓(xùn),使他們能在DCS控制系統(tǒng)的搭建,網(wǎng)絡(luò)通訊的建立、硬件的測(cè)試和驗(yàn)收、程序組態(tài)的設(shè)計(jì)、控制回路的測(cè)試和調(diào)整等工作中逐步擔(dān)起重任。同時(shí),要充分利用設(shè)備調(diào)試及分步投運(yùn)過(guò)程中出現(xiàn)的問(wèn)題,要求他們?cè)诠?yīng)商的協(xié)助下,能結(jié)合技術(shù)手冊(cè),進(jìn)行分析、判斷和解決。在此基礎(chǔ)上,這些熱控工程師向其他人控人員進(jìn)行“在線”培訓(xùn)。對(duì)于控制系統(tǒng)的管理,需特別提醒:在機(jī)組運(yùn)行的情況下,應(yīng)盡量避免在線修改組態(tài)和重要參數(shù),若實(shí)在是必須進(jìn)行組態(tài)修改及下載時(shí),要作好事故預(yù)想,落實(shí)各項(xiàng)安全措施,并完善相關(guān)報(bào)批手續(xù)。
DCS控制系統(tǒng)在發(fā)電廠的廣泛應(yīng)用使得現(xiàn)代電廠的自動(dòng)化水平躍上了新的臺(tái)階。在工業(yè)實(shí)踐中,控制系統(tǒng)出現(xiàn)問(wèn)題是正常的,但我們工程技術(shù)人員有責(zé)任和義務(wù)使控制系統(tǒng)盡可能少地出現(xiàn)嚴(yán)重影響安全的問(wèn)題。對(duì)于控制系統(tǒng)多次出現(xiàn)的問(wèn)題,我們要多分析,勤總結(jié),尋找問(wèn)題的共性,并有針對(duì)性地采取措施進(jìn)行改進(jìn)。由于本人知識(shí)面不廣,經(jīng)驗(yàn)也有限,加之時(shí)間倉(cāng)促,文中的表述欠全面和完整,歡迎批評(píng)指正。希望能拋磚引玉,和廣大DCS技術(shù)人員加強(qiáng)溝通和交流,互相取長(zhǎng)補(bǔ)短,使DCS控制系統(tǒng)能更好地為安全經(jīng)濟(jì)的電力生產(chǎn)服好務(wù)。
