Study of High Altitude Ultra High Voltage Transmission Line Monitoring System

文章介绍了依靠新通信、新供电、电磁防护、数据采集、数据可视化等技术,消除传统监测系统中的技术缺陷。并结合青海电网750kV输电线路实际应用环境特点,重点解决项目应用中通信、塔上供电、电磁防护等难题,实现实时高清晰度监控图像以及监测数据(如微气象、导线温度、泄露电流等)的采集、显示、分析、管理等功能,为电网安全生产提供支持,为智能电网、物联网在输电线路中的应用奠定了基础,并积极拓展输电线路信息采集量,提高输电线路在线监测智能分析及灾害预警的能力。

Relying on a combinatory of new communication technologies, power supply technologies, electromagnetic protection technologies, data acquisition technologies and data visualization technologies, this paper studies a high altitude ultra high voltage transmission line monitoring system, which considers the environment characteristics of 750kV transmission line in Qinghai power grid, removes the technique defects in the traditional monitoring system, solves the challenges of communication, power supply and electromagnetic protection, and implements several functions including collection, display, analysis and management of real-time high definition monitoring image and data. The system can not only provide a support for secure production and lay a good foundation for application of the system to the transmission lines of smart grid and internet of things, but also actively expand transmission lines information collection and improve the ability of intelligent online monitoring, analysis and disaster warning of transmission lines.
