華能上都(dou)發(fa)(fa)電有限(xian)責任公司#3機組(zu)于2007年(nian)投(tou)產,原DCS系(xi)統(tong)已運行(xing)多年(nian),硬件(jian)(jian)故(gu)障(zhang)頻(pin)發(fa)(fa),DPU等(deng)(deng)(deng)硬件(jian)(jian)屬國外廠家(jia)淘(tao)汰(tai)產品(pin),無法購置(zhi)備(bei)(bei)(bei)品(pin)備(bei)(bei)(bei)件(jian)(jian),亟需(xu)進(jin)行(xing)DCS改(gai)(gai)造。本次改(gai)(gai)造涵(han)蓋鍋爐、汽機、發(fa)(fa)變(bian)組(zu)及廠用電等(deng)(deng)(deng)系(xi)統(tong)設備(bei)(bei)(bei),同時將原先由PLC獨立控(kong)(kong)制(zhi)(zhi)的蒸汽吹灰、冷(leng)風加熱、空(kong)(kong)壓(ya)機控(kong)(kong)制(zhi)(zhi)、供暖(nuan)空(kong)(kong)調等(deng)(deng)(deng)系(xi)統(tong)改(gai)(gai)造為(wei)DCS控(kong)(kong)制(zhi)(zhi),實現(xian)主(zhu)機統(tong)一監(jian)控(kong)(kong)。
項目啟動后,南瑞繼保立即與西安熱(re)工(gong)院組(zu)建DCS項目服務(wu)(wu)團隊(dui),在嚴格做好(hao)疫情(qing)防控的同時,努(nu)力(li)克服工(gong)期緊、任務(wu)(wu)重等(deng)諸(zhu)多困(kun)難,歷經(jing)50多個日夜的連續奮戰,在各參建單位的積極配合(he)與協(xie)助下,順(shun)利完成了鍋(guo)爐水(shui)壓(ya)試(shi)驗、鍋(guo)爐動力(li)場試(shi)驗、鍋(guo)爐點火、汽機沖(chong)轉、并(bing)網發電等(deng)節(jie)點里程碑。
本項目中(zhong)(zhong)南瑞(rui)繼保(bao)(bao)與(yu)西安熱工(gong)(gong)院緊密合作(zuo),共(gong)同完(wan)成組態(tai)調(diao)(diao)試工(gong)(gong)作(zuo),在邏(luo)輯傳動過程(cheng)中(zhong)(zhong)多(duo)次召開專題討論(lun)會議,對邏(luo)輯變更、安全措施、調(diao)(diao)試步驟等各項工(gong)(gong)作(zuo)進行詳細部署,確保(bao)(bao)了(le)項目改造的順(shun)利進行。DCS項目服(fu)(fu)務(wu)團隊在改造過程(cheng)中(zhong)(zhong)提(ti)供了(le)優質(zhi)產品和(he)高效服(fu)(fu)務(wu),積累了(le)600MW空冷機組的調(diao)(diao)試經驗,獲得了(le)用戶對南瑞(rui)繼保(bao)(bao)技術實力(li)、產品質(zhi)量和(he)工(gong)(gong)程(cheng)實施交付能力(li)的廣泛(fan)認(ren)可。
自(zi)主(zhu)可控DCS系統(tong)(tong)在600MW等(deng)級火電(dian)機組的(de)(de)成功投運,進一步驗證了該系統(tong)(tong)的(de)(de)可靠性和適(shi)用性。南瑞繼(ji)保將繼(ji)續發(fa)揮多專業深(shen)度(du)融合的(de)(de)技術(shu)優勢,研究(jiu)新技術(shu),開拓新領域,不(bu)斷提(ti)升產品交付能力,在大型火電(dian)廠熱工電(dian)氣二次一體(ti)化控制(zhi)方(fang)向砥礪奮(fen)進,為用戶提(ti)供功能更加(jia)先(xian)進的(de)(de)控制(zhi)保護(hu)產品。
