【摘要】：水電機組穩(wěn)定性與水頭、負荷等相關(guān)狀態(tài)以及機組運行工況關(guān)系密切,孤立的穩(wěn)定性監(jiān)測與分析將會降低分析結(jié)果準確性。本文在研究了穩(wěn)定性故障特征與影響因素的基礎(chǔ)上,在水電站最優(yōu)維護系統(tǒng)(HOMIS)集成框架下,提出了基于工況關(guān)聯(lián)規(guī)則的穩(wěn)定性分析方法。該方法結(jié)合機組運行工況與相關(guān)狀態(tài)信息,劃分工況模式空間、計算穩(wěn)定性性能指標、構(gòu)造工況關(guān)聯(lián)規(guī)則,并依據(jù)關(guān)聯(lián)規(guī)則實現(xiàn)對穩(wěn)定性的綜合關(guān)聯(lián)分析。目前,該方法已成功應(yīng)用于葛洲壩電站22臺機組穩(wěn)定性分析,實際分析結(jié)果表明,該方法在穩(wěn)定性性能下降檢測、故障預(yù)測以及運行規(guī)律挖掘等方面具有很好的應(yīng)用前景。
[Abstract]:The stability of hydropower unit is closely related to water head, load and operating conditions, and isolated stability monitoring and analysis will reduce the accuracy of the analysis results. Based on the integrated framework of optimal maintenance system (HOMISS) of hydropower stations, a stability analysis method based on operating condition association rules is proposed, which combines the information of unit operation conditions and related states, divides the operating mode space, and calculates the stability performance index. At present, the method has been successfully applied to the stability analysis of 22 units in Gezhouba Hydropower Station. This method has a good application prospect in stability degradation detection, fault prediction and operation rule mining.
