基于分布式实时数据库的线损一体化监测方法

Integrated Line Loss Monitoring Method Based on Distributed Real-time Database

针对数据特征量提取能力较差、难以准确监测出线路波形的问题,基于分布式实时数据库提出一种新的线损一体化监测方法。以区段为单位,从负荷形状数据中提取线损参数,并计算负荷形状系数、线损参数。将分布式实时数据库中的数据片段融入到各类节点中,形成等效节点网络,在等效节点网络中形成节点容量矩阵能够更有效地计算出支路功率。在线损四分监测与线损异常监测两个角度建立线损一体化监测模型,对比计算实时线损数值与线路分支接头处线损数值,判断是否存在窃电行为。实验结果表明,基于分布式实时数据库的线损一体化监测方法能够很好地提取数据特征量、分析线路波形、得到更准确的监测波形、提高监测效果、实现线损一体化监测。

Aiming at the problem that the ability of data feature extraction is poor and accurately monitor the line waveform is difficult,a new integrated line loss monitoring method based on distributed real-time database is studied.Taking the section as the unit,we extract the line loss parameters from the load shape data,calculate the load shape coefficient and line loss parameters,integrate the data fragments in the distributed real-time database into various nodes to form an equivalent node network,form a node capacity matrix in the equivalent node network,and calculate the branch power more effectively.An integrated line loss monitoring model is established from the perspectives of on-line loss quartering monitoring and line loss anomaly monitoring.The real-time line loss value is compared with the line loss at the line branch joint to judge whether there is a power theft.The experimental results show that the integrated line loss monitoring method based on distributed real-time database can well extract the data features and analyze the line waveform,also can obtain more accurate monitoring waveform,improve the monitoring effect and realize the integrated line loss monitoring.
