【摘要】:對風(fēng)電的研究往往要依托于歷史功率數(shù)據(jù),而風(fēng)電機組采集到的歷史數(shù)據(jù)中往往含有大量的異常數(shù)據(jù),這嚴重影響了對風(fēng)電功率規(guī)律特性的分析。針對風(fēng)電機組的實測功率數(shù)據(jù)進行研究,分析風(fēng)速升降特征與風(fēng)向特征對風(fēng)電機組輸出功率的影響。將不同的風(fēng)特征的數(shù)據(jù)分開討論,分別利用Copula函數(shù)得到概率功率曲線,結(jié)合異常數(shù)據(jù)的時序特征歸納出三類異常數(shù)據(jù),建立異常數(shù)據(jù)識別模型。利用風(fēng)電機組的實際數(shù)據(jù)和人工生成數(shù)據(jù)進行仿真分析,結(jié)果表明,該方法能夠高效地識別各類異常數(shù)據(jù),對風(fēng)電研究有著重要的意義。
[Abstract]:The research of wind power often relies on historical power data, and the historical data collected by wind turbines often contain a large number of abnormal data, which seriously affects the analysis of wind power characteristics. The influence of different wind characteristics on power is discussed separately. The probabilistic power curves are obtained by Copula function, and three kinds of abnormal data are summed up according to the time series characteristics of abnormal data. It is of great significance for wind power research to identify all kinds of abnormal data efficiently.
