无人机用于输电线路巡检的作业流程及应用

相比人工巡检模式,采用无人机巡检将大幅提高电网运检效率。但无人机巡检作业目前仍处于试验阶段,缺乏统一、规范的巡检作业流程。根据无人机在南方电网贵州某超高压输变电工程的实际巡检作业应用,提出了一套科学合理的巡检作业流程,并对该套无人机巡检作业流程的高效性进行实地检验。试验结果表明:无人机巡检不仅可有效降低企业人工投入成本,而且能克服由于复杂地形、极端天气等人为不可控因素而无法进行巡检作业的情况,极大地提高了巡检作业范围和效率。

Operation process of the application of unmanned aerial vehicle (UAV) to transmission line inspection

In comparison with traditional manual inspection, the adoption of unmanned aerial vehicle (UAV) can improve the grid inspection efficiency. However, the application of UAV to electric inspection was still in trial stage. It lacked the unified standard operation process. Based on the practical inspection of an extra-high voltage transmission and transformation project in Guizhou South China Power Grid by UAV, a scientific and reasonable inspection process has been put forward. The field validation of this inspection process has been conducted. The results showed that UAV inspection could not only reduce the cost input of human resource, but also overcome the inspection failure caused by complex terrain, extreme weather and other uncontrollable factors. The scopes and efficiency of inspection operations have been improved significantly.
