Reliability monitoring system of power transmission line applied to smart grid

Abstract

The invention provides a reliability monitoring system of a power transmission line applied to a smart grid. The system comprises: a collection module arranged onsite and used for collecting image information of the monitored power transmission line and transmitting a collected power transmission line image to a monitoring center in real time; and the monitoring center used for receiving the powertransmission line image sent by the collection module, performing analysis processing on the image information to extract a contour of the power transmission line in the power transmission line imageand all foreign matter contours near the power transmission line, comparing the contour of the power transmission line and all foreign matter contours with a pre-stored power transmission line contour template and an electrical component contour template to judge whether a foreign matter exists around the power transmission line, and sending early warning information when discovering the foreignmatter. The reliability monitoring system provided by the invention analyzes the reliability of the power transmission line according to the image information of the power transmission line, so that the intelligence level is high, the operation is simple, no manual participation is required, the implementation property is high, no influence is generated by external factors such as weather, the workload of the operation and maintenance personnel is reduced, and the accuracy is high.

Description

technical field [0001] The invention relates to the technical field of smart grids, in particular to a reliable monitoring system for transmission lines applied to smart grids. Background technique [0002] With the rapid development of the national economy, electricity has become an indispensable product in daily life and industrial production, and the reliability of power transmission has an increasing impact on social development. At present, the reliability monitoring technology for the internal electrical signal of the transmission line is very mature, but with the increase of the operating life, the transmission line and its electrical components will inevitably be missing or attached to foreign objects, which will not only make the limit of the transmission line The discharge distance becomes shorter, and when foreign matter penetrates adjacent lines, it will also cause phase-to-phase short circuit or open circuit of the transmission line, resulting in large-scale pow...

Problems solved by technology

[0003] At present, the external monitoring of transmission lines mostly adopts the method of manual inspection. Since the transmission lines work in the wild all year round, the geographical conditions are diverse, the climate is complex and changeable, manual monitoring is difficult, costly, inefficient, and seriously affected by weather.
