FANUC 8705THA005S1W1NGL1(1) 依據(jù)鍋爐對每個煤倉的加倉懇求,加倉前由運煤操控室的值班人員調(diào)出加倉畫面,一起通過鍵盤輸入給定加倉指令,完結(jié)主動加倉配煤。首要完結(jié)了分單元加倉功用。
(2) 加倉開端,先順次給呈現(xiàn)超低煤位倉配煤,直至消除煤倉的悉數(shù)低煤位信號。
(3) 悉數(shù)的低煤位信號不見后,再進行次第配煤,當倉滿后轉(zhuǎn)到下一個煤倉進行次第配煤,直到悉數(shù)的煤倉滿為止。
(4) 次第配煤進程中,假如又呈現(xiàn)超低煤位、低煤位倉,則中止原煤倉次第加倉程序,優(yōu)先為超低煤位、低煤位倉配煤,消除超低煤位、低煤位,再轉(zhuǎn)入次第加倉程序。
(5) 當悉數(shù)煤倉呈現(xiàn)滿煤位信號(并報警)后,程序主動停機并把皮帶上的余煤均勻分配給各煤倉。
(6) 在配煤進程中能主動越過滿倉、高煤位倉、超高煤位倉及修理倉。
(7) 配煤的尾倉設定、修理倉設定均通過上位機進行設定,加倉時尾倉及其后方煤倉均不答應配煤。
5、界面顯現(xiàn)
界面上首要完結(jié)了操控辦法設置和流程挑選菜單,運煤技能流程圖,實時運煤體系作業(yè)圖,設備情況顯現(xiàn)圖,前史數(shù)據(jù)顯現(xiàn)畫面,毛病報警一覽表,皮帶機的作業(yè)顯現(xiàn),煤倉煤位的顯現(xiàn),各皮帶、碎煤機、輪斗機電機電流的顯現(xiàn),悉數(shù)輸煤體系的各個需要監(jiān)督的有些均能在操作員站上顯現(xiàn)出來,可以極好的避免輸煤事端的發(fā)作,極大的進步了輸煤體系的主動化水平。
6、結(jié)束語
將dcs體系運用到華祥熱電有限公司的輸煤程控體系中,可以極好的體現(xiàn)dcs體系的優(yōu)勢,將輸煤體系需要監(jiān)督的模仿量、開關量集成到悉數(shù)操控體系中,監(jiān)督皮帶的電機電流的改動,完結(jié)皮帶上下級的連鎖功用,完結(jié)主動加倉功用,進步了該電廠的主動化水平,也為將來廠級網(wǎng)絡的互連預備了充沛的條件。科遠廠級監(jiān)控信息體系(SIS)的運用
SIS(Supervisory Inbation System of power plant),即火電廠廠級監(jiān)控信息體系,是銜接全廠操控體系或智能外表的實時數(shù)據(jù),包含DCS、輔佐車間操控、熱網(wǎng)等,并以實時數(shù)據(jù)為根底,以安全經(jīng)濟作業(yè)和進步電廠全體效益為意圖,在全廠方案內(nèi)完結(jié)出產(chǎn)信息同享并為全廠實時出產(chǎn)進程歸納優(yōu)化效勞的出產(chǎn)進程實時處理和監(jiān)控的信息體系。它是完結(jié)從DCS體系到處理信息體系MIS的橋梁,然后在全廠方案內(nèi)完結(jié)信息同享和管控一體化。
科遠自2000年開端研制廠級監(jiān)控信息體系(SIS),被評為2005年度國家要點新商品和中國軟件職業(yè)協(xié)會的“2004年度優(yōu)異軟件商品”、“2005年度優(yōu)異軟件商品”。具有自立常識產(chǎn)權的SyncBASE實時數(shù)據(jù)庫軟件在國內(nèi)電力職業(yè)中占有了主導的方位。此外該公司共獲得了四項軟件著作權、三項國家掛號軟件商品、并獲得了四項專利。
截止2008年末,科遠已成功施行逾越數(shù)十個大中型電廠廠級監(jiān)控信息體系項目,獲得了用戶的一起好評。
