Overhead Line Intelligent Power Transmission And Online Transmission Solution

Overview

In the power industry, most high-voltage transmission lines and tower baseshave linear distribution and aregeographically located atsparsely populated places. These locations are oftenunattended or lessattended, and thegeographical environment and climatic conditions are relatively harsh. In recent years, various accidents, such as icing on transmission lines, conductor galloping, tilting of towers, and damagecaused byexternal force, have occurred frequently in China, resulting in huge losses. Establishment of an overhead line intelligent transmissionandonline monitoring systemcan effectively prevent such problem. Based oncomprehensive online monitoring of overhead lines in all dimensions, real-timeperception ofthe line operation state hasgreat guiding significanceto operation and maintenance.

Application Scenarios

The solution can be applied to online monitoring of overhead lines for power transmission with various voltage levels.

Features

By employing advanced sensors for measurement, wireless ad-hoc network, micro power consumption, artificial intelligence and edge computing, the overhead line intelligent power transmission and online monitoring system constructs an IoT for power transmission equipment. Information, such as the strain clamp temperature of transmission line, weather conditions of line, conductor galloping, tilting of towers and micro-tick monitoring, is transmitted to the background monitoring center. This solution can achieve comprehensive perception of equipment, panoramic monitoring of channel and cloud-edge processing of data, so as to realize all-weather monitoring of the comprehensive situation of transmission lines. It provides an integrated solution for fault monitoring and early warning of overhead lines, At the same time, the system requires less manpower for transportation and inspection, which is of great significance to the operation and maintenance of overhead lines.

Performance Cases

AI visual online monitoring project for Guangdong Shenzhen East Area I 500kV Lingkun Line and East Area II 220kV Junbai A Line

This project is located in Shenzhen, Guangdong Province, which involves the Shenzhen East Area I 500kV Lingkun A Line, the East Area II 220kV Junbai A Line and the East Area III 220kV Junwu A and B Lines, with a total of more than 800 sets of AI visual online monitoring devices, and CYG Sunri provides the integrated solution for the project. The devices are installed on the poles and towers of power line to monitor transmission line channels, insulators, conductors and wire fittings in real time. The images and videos are uploaded to the transmission monitoring center via the APN power private network. Huawei Atlas200 module is built into the devices, which can realize front-end AI analysis and processing, and remotely monitors and alarms hidden dangers such as foreign bodies, construction vehicles and high trees, providing users with more comprehensive, scientific and advanced full-dimensional monitoring services.
