输电线路山火隐患可视化预警分析

Visualized Warning Analysis of the Wildfire Danger along Transmission Lines

输电线路周边燃起山火容易发展引起跳闸事故,对电网运行安全造成重大损害。随着输电线路可视化视频监控装置日臻完善,运维人员已可以从可视化预警中准确获取线路山火信息。为掌握线路山火发生特点,本文从线路运维的角度,利用青岛地区可视化监控中心山火预警台账,从山火起因、发生时间、重点电压等级、区域性等多个维度,对山火发生规律做出总结,进而给出线路山火防范建议。

The wildfire along transmission lines easily results in the tripping accidents,which threatens the safety of the power grid operation.As the development of visualized monitoring devices on the transmission tower,the early warning messages of wildfire can be obtained by the operators conveniently.In order to summarize the occurring characteristics of the wildfire along transmission lines,a dimensional analysis is made from the cause,occurrence time,focal voltage level and regions in this paper.So the occurrence of wildfires can be concluded and then the targeted countermeasures are provided to the transmission line operators.
