Problems solved by technology

For a long time, in order to prevent accidents caused by cable faults, it is necessary to insist on regular and fixed-point inspections of cables in operation, while traditional inspections require manual on-site inspections when the power is cut off, and the inspection cycle is long, and cables cannot be found in time. Failure, can no longer meet the current economic and social development requirements

Abstract

The present invention discloses a big data-based power cable monitoring system and monitoring method. The system comprises a sensor module, a task scheduling module, a storage module, a cable comprehensive diagnosis module and a monitoring module. The sensor module is used for acquiring the data of a monitored object. The task scheduling module is used for starting the task scheduling operation according to an operation request submitted by a user. The storage module is used for storing real-time monitoring data and off-line historical data. The cable comprehensive diagnosis module is used for analyzing and processing data and sending out a fault alarm. The monitoring module is used for displaying and monitoring the treatment result of the cable comprehensive diagnosis module. According to the technical scheme of the invention, based on the HDFS, massive text data are stored and managed. Based on the k-means clustering algorithm in combination with a Spark computing engine, the collected massive data are subjected to the clustering treatment and analysis. Therefore, the fault point of a power cable can be quickly positioned.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a power cable monitoring system and a monitoring method. Background technique [0002] In order to solve energy security and environmental protection issues, cope with climate change, seize the commanding heights of the industry, and create new economic growth points, the construction of smart grids in countries around the world has been fully launched. Smart grid technology is a new type of modern grid that highly integrates advanced sensor technology, information and communication technology, analysis and decision-making technology, automatic control technology, energy power technology and grid infrastructure to achieve a high management and control. The power cable plays a role of connecting resources in the resource allocation process of the entire power system. The performance of the power cable determines the safety of the production and operation of the power system. Therefor...
