【摘要】：運(yùn)行工況識別作為風(fēng)電機(jī)組狀態(tài)監(jiān)測與健康管理領(lǐng)域的重要環(huán)節(jié),往往受到不確定信息以及高速實(shí)時(shí)數(shù)據(jù)流的影響,造成健康狀態(tài)評估難以有效實(shí)施。在此背景下,文中提出一種基于Spark流式處理的健康狀態(tài)實(shí)時(shí)評估方法。首先,采用大數(shù)據(jù)分析技術(shù)實(shí)現(xiàn)風(fēng)電機(jī)組運(yùn)行工況的空間劃分;然后,在充分考慮風(fēng)電機(jī)組監(jiān)測信息不確定性的情況下,結(jié)合數(shù)據(jù)采集與監(jiān)控(SCADA)歷史運(yùn)行數(shù)據(jù),對基于高斯云模型和高斯云變換的健康狀態(tài)評估模型進(jìn)行訓(xùn)練,并以健康指數(shù)作為風(fēng)電機(jī)組健康狀態(tài)評估的指標(biāo)。最后,將該評估方法應(yīng)用在中國北方某風(fēng)電場1.5 MW風(fēng)電機(jī)組故障前的健康狀態(tài)評估中。算例分析結(jié)果表明,該方法可監(jiān)測到風(fēng)電機(jī)組健康狀態(tài)的變化趨勢,初步實(shí)現(xiàn)了故障的早期預(yù)警。
[Abstract]:As an important link in the field of wind turbine condition monitoring and health management, operating condition identification is often affected by uncertain information and high speed real-time data flow, which results in the difficulty of effective implementation of health status assessment. In this context, a real-time assessment method of health status based on Spark flow processing is proposed. First of all, big data analysis technology is used to realize the space division of wind turbine operating conditions, and then, with full consideration of the uncertainty of monitoring information of wind turbines, the historical operation data of SCADAs are combined with data acquisition and monitoring. The health state assessment model based on Gao Si cloud model and Gao Si cloud transformation is trained, and the health index is used as the index of wind turbine health assessment. Finally, the method is applied to evaluate the health status of a 1.5 MW wind turbine unit in northern China before failure. The result of example analysis shows that the method can monitor the change trend of wind turbine's health state and realize the early warning of failure.
