摘　　要：在传统的线损率异常诊断方法中,低压配电台区数据与诊断的线损异常数据之间的重叠部分存在较好的相关性,导致异常诊断的准确性降低。为此,设计了一种基于数据驱动技术的低压配电台区异常线损率诊断方法。提取低压配电台区线损数据的主要成分特征,对具有重叠分区的冗余数据进行处理,利用数据驱动技术和闭环低压智能运行分析平台构建线损率异常诊断模型,分析了低压配电台区线损的合理区间,实现了对低压配电台区线损率异常的准确诊断。通过与其他方法对比,验证了该方法诊断准确率较高,具有较高的实用价值。In the traditional diagnosis method of line loss rate,there is a good correlation between the overlapped data of low-voltage distribution area and the diagnosed line loss data,which leads to the decrease of the accuracy of the diagnosis.Therefore,a data-driven method for diagnosing abnormal line loss rate in low-voltage distribution area is designed.The main component characteristics of the line loss data in the low-voltage distribution area were extracted,the redundant data with overlapping partitions were processed,and the abnormal diagnosis model of line loss rate was constructed by using data-driven technology and closed-loop low-voltage intelligent operation analysis platform.The reasonable range of line loss rate in the low-voltage distribution area was analyzed,and the accurate diagnosis of abnormal line loss rate in the low-voltage distribution area was realized.Compared with other methods,it is proved that this method has high diagnostic accuracy and practical value.
