電站設(shè)備狀態(tài)評(píng)價(jià)與預(yù)測(cè)系統(tǒng)的研究.pdf

1、華北電力大學(xué)碩士學(xué)位論文摘要本文針對(duì)我國(guó)電站設(shè)備狀態(tài)維修存在的問題，研究了電站設(shè)備狀態(tài)評(píng)價(jià)與預(yù)測(cè)系統(tǒng)。構(gòu)建了該系統(tǒng)的體系結(jié)構(gòu)，分析了狀態(tài)評(píng)價(jià)與預(yù)測(cè)方法，并利用電站設(shè)備實(shí)例來驗(yàn)證所建的體系方法，其結(jié)果表明該體系有效、可行。在此基礎(chǔ)上，對(duì)電站設(shè)備狀態(tài)評(píng)價(jià)一與預(yù)測(cè)系統(tǒng)進(jìn)行總體設(shè)計(jì)以及各模塊功能設(shè)計(jì)，采用C#和JavascriPt語言完成了該系統(tǒng)軟件的開發(fā)。電站設(shè)備狀態(tài)評(píng)價(jià)與預(yù)測(cè)系統(tǒng)為電站設(shè)備提供狀態(tài)評(píng)價(jià)和預(yù)測(cè)診斷平臺(tái)，能夠客觀地診斷出故障所發(fā)

2、生的部位、原因及其趨勢(shì)等重要信息，為狀態(tài)維修提供依據(jù)。關(guān)鍵詞:電站設(shè)備，狀態(tài)評(píng)價(jià)，狀態(tài)預(yù)測(cè)，狀態(tài)維修ABSTRACTAimingattheProblemsofeondition一basedmaintenaneeforPowerPlantequiPmentinoureountry，theeonditionevaluationandPredietionsystemofPowelPlantequiPment15researehedinthis
