Online monitoring and early warning technology for the status of earth wire for overhead line

Abstract

Overhead lines for wind power transmission in the southern region have the characteristics of large tower-line elevation, across thick ice areas, harsh natural environments, and difficult maintenance. Unpredictable line breakage accidents often occur, affecting the stability of the social power supply. This paper designs and introduces a technology based on intelligent perception technique for online monitoring of the earth wire, which can realize long-term real-time online monitoring of the state of the earth wire of overhead lines and solve the problem of line monitoring from wind power transmission and fault inspection and troubleshooting. Now the test and monitoring work of an overhead transmission line has been completed during the ice period, and the test results show that the technology has good monitoring performance.

GPS/Beidou fusion positioning technology for transmission line grounding line

“…In the power system, the grounding wire is an important safety device during power maintenance, providing protection for the personal safety of workers [1]. The process of installing and removing transmission grounding wires mainly includes outbound delivery, transportation, on-site installation, removal completion, loading and return, and inventory management.…”
