摘 要:針對(duì)發(fā)電設(shè)備故障頻發(fā)的情況,基于現(xiàn)場實(shí)時(shí)數(shù)據(jù)建立設(shè)備正常的運(yùn)行狀態(tài)模型并結(jié)合PI實(shí)時(shí)數(shù)據(jù)庫構(gòu)建了發(fā)電機(jī)組及關(guān)鍵設(shè)備的在線預(yù)警系統(tǒng),對(duì)所采集的數(shù)據(jù)進(jìn)行處理、分析、預(yù)測,來判斷設(shè)備的運(yùn)行狀態(tài)并幫助運(yùn)行人員確認(rèn)設(shè)備是否需要檢修。通過電廠實(shí)際運(yùn)用表明,該系統(tǒng)大幅提高了設(shè)備運(yùn)行的安全水平和效率,降低了運(yùn)行維護(hù)成本。
關(guān)鍵詞:數(shù)據(jù)驅(qū)動(dòng);在線預(yù)警;發(fā)電設(shè)備

Abstract: In allusion to the circumstance of power generating equipment faults taking place frequently, the normal operational state model was established based on the site real-time data, and combined with the PI real-time database, the online early warning system of generator set and key equipment was constructed to carry out disposal, analysis and prediction to judge the equipment operating state and to help the operator determine whether to overhaul the equipment. The practical application of power plant shows that this system drastically improves the safety level and efficiency of equipment operation and reduces the operating maintenance cost.
Key words: data driven; online early warning; power generating equipment
