摘　　要：针对区域配电线路绝缘故障类型较多、故障监测难度较大的问题,设计一种基于时间序列的区域配电线路绝缘故障多类型精准监测方法。采用HHT信号处理技术分解信号,叠加分解后的信号分量和参与信号分量;建立配电线路绝缘故障时序模型,计算时域特征量、频域特征量与熵值域特征量,对任务优先级排序;引入欧氏距离中心点概念,融合故障结果,实现区域配电线路绝缘故障多类型监测。实验结果表明,该监测方法不仅提高了多种故障的监测准确性,还提高了监测的实时性。To address the issue of multiple types of insulation faults in regional distribution lines and the difficulty of fault monitoring,a multi type accurate monitoring method for insulation faults in regional distribution lines is designed based on time series.Using HHT signal processing technology to decompose the signal,overlaying the decomposed signal components and participating signal components,it establishes a time series model for insulation faults in distribution lines,calculates time-domain feature quantities,frequency-domain feature quantities,and entropy value domain feature quantities,and prioritizes tasks.It introduces the concept of Euclidean distance center point and integrating fault results to achieve multi type monitoring of insulation faults in regional distribution lines.The experimental results show that this monitoring method not only improves the monitoring accuracy of various faults,but also improves the real-time monitoring.
