摘要
为防止冰灾对输电设施造成大面积破坏,实时监测线路运行状况,广东电网公司借鉴国内外已有输电线路预警系统的经验,建设了广东电网覆冰在线监测系统。为此,对该系统的建设思路和原则、结构、功能和关键技术进行了详细的介绍,实际应用证明:该系统可实现对线路走廊图像、气象、覆冰、导线温度等的实时监测,并能发出预警信息,具有使用方便、运行可靠等特点。
To prevent large-area damage of power transmission facilities by icing disaster and enable real-time operation monitoring on power lines, Guangdong Power Grid Corporation drew on the experience of existing transmission line prewarning system at home and abroad, and constructed the on-line icing monitoring system for Guangdong power grid. The construction idea and principle, structure, function and key techniques of the system are described in detail. It is proved in practice that the system can realize real-time monitoring on line-corridor images, weather, icing, conductor temperature, etc. and send warning information, featuring ease of use and operational reliability.
