针对风速缺失与异常数据修复问题,考虑到风速采样网络中的节点数据相关性,提出了一种基于参考序列与全卷积网络的风速数据缺失与异常修复方法。首先,构建了基于全卷积插值网络与全卷积门控网络的数据修复模型。然后,利用全卷积插值网络计算无参考修复数据,利用全卷积门控网络计算无参考修复数据与参考数据的权重系数,并将两种数据带权重求和得到最终修复数据。最后,使用两个风电场数据验证了所提方法的效果。结果表明,与其他无参考修复方法相比,所提方法能够利用相近节点的参考风速数据,提高目标节点的风速时序数据修复精度。
Aiming at the repair problem of missed and abnormal wind speed data
considering the correlation of node data in wind speed sampling network
a repair method for missed and abnormal wind speed data based on the reference sequence and full convolution network is proposed. Firstly
a data repair model based on the full convolution interpolation network and full convolution gate control network is constructed. Then
the full convolution interpolation network is used to calculate the non-reference repair data
the full convolution gate control network is used to calculate the weight coefficient of the non-reference repair data and the reference data
and the two kinds of data are weighted and summed to get the final repair data. Finally
the algorithm effect is verified using the data of two wind farms. The results show that
compared with other non-reference repair methods
the proposed method can use the reference wind speed data of similar nodes to improve the repair accuracy of wind speed time-series data of target nodes
