Embodiment Construction

[0068] In order to better understand the present application scheme, the technical solutions in the present application embodiment will be apparent from the drawings in the present application, and the described embodiments are clearly described herein. It is an embodiment of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative labor premises, all of the present application protected.

[0069] Due to the large number of LTUs in the low-voltage distribution network, the overall amount of data is large, and it is often easy to detect in time due to abnormal working state, which in turn affects fault detection and processing, reducing the reliability of low voltage distribution network, and such The abnormality investigation is more time-consuming, and an additional amount of operational work is added; and for the low voltage distribution n...

Abstract

The invention discloses a low-voltage power distribution monitoring terminal data acquisition anomaly detection method and system, and the method comprises the steps: carrying out the clustering analysis of a pre-processed data sample of a low-voltage power distribution terminal through a clustering algorithm based on density, and obtaining an abnormal data sample; and judging whether the low-voltage power distribution terminal is abnormal in data acquisition or not according to the number of the abnormal data samples. According to the invention, anomaly detection is carried out on data acquisition of the low-voltage power distribution terminal, and meanwhile, the accuracy of anomaly detection is improved based on standardized processing and data cleaning of data samples of the low-voltage power distribution terminal.

Description

Technical field [0001] The present application relates to the field of networking and distribution thereof, more particularly to a low voltage power distribution monitoring terminal the data acquisition system and method of detecting abnormality. Background technique [0002] Endmost link low voltage distribution network distribution system is located, is directly facing the end user, thus, reliable operation of the low-pressure distribution grid is an important part of the overall power grid reliability chain. [0003] At present, my country's low-voltage distribution network has a wide geographical distribution, and other characteristics of complex network architectures, and most are not monitored in the state. To solve the problems of the conventional low-voltage distribution network blind tube, a large number of low-voltage distribution terminal (low-voltage terminalunit, LTU) is mounted on the low voltage distribution network for real-time collection line operating data, and...
