電站設備狀態(tài)評價與預測系統(tǒng)的研究.pdf

1、華北電力大學碩士學位論文摘要本文針對我國電站設備狀態(tài)維修存在的問題，研究了電站設備狀態(tài)評價與預測系統(tǒng)。構(gòu)建了該系統(tǒng)的體系結(jié)構(gòu)，分析了狀態(tài)評價與預測方法，并利用電站設備實例來驗證所建的體系方法，其結(jié)果表明該體系有效、可行。在此基礎上，對電站設備狀態(tài)評價一與預測系統(tǒng)進行總體設計以及各模塊功能設計，采用C#和JavascriPt語言完成了該系統(tǒng)軟件的開發(fā)。電站設備狀態(tài)評價與預測系統(tǒng)為電站設備提供狀態(tài)評價和預測診斷平臺，能夠客觀地診斷出故障所發(fā)

2、生的部位、原因及其趨勢等重要信息，為狀態(tài)維修提供依據(jù)。關鍵詞:電站設備，狀態(tài)評價，狀態(tài)預測，狀態(tài)維修ABSTRACTAimingattheProblemsofeondition一basedmaintenaneeforPowerPlantequiPmentinoureountry，theeonditionevaluationandPredietionsystemofPowelPlantequiPment15researehedinthis
