多旋翼无人机巡查系统在特高压基建工程中的应用

针对冀北地区特高压电网基建现状,提出了利用无人机巡查作为建设管理新技术手段。对多旋翼无人机系统构成、飞行控制系统进行阐述,为满足控制需求对其进行建模并进行系统分析。结合电网基建工程实际特点,建立了无人机巡查评估方案,建立检查表法与专项方案事故树分析法,从定性和定量计算两方面对基建现场进行评估分析。最后根据实际应用效果,从巡查时间和费用、安全风险、外协赔偿、环评水质保护等方面衡量了无人机巡查效能。无人机巡查电网基建,能拓宽管控范围,减少管控漏洞,降低管控风险,提高工作效率。

Application of Multi-Rotor UAV Patrol System in UHV Power Grid Construction

In view of the present situation of ultra-high voltage(UHV) power grid construction in northern Hebei, the multi-rotor UAV patrol inspection is proposed as a new technique for construction management. Based on the characteristics of multi-rotor UAV’s structure and flight control system, a model is constructed to make a systematical analysis. In light of the actual characteristics of power grid construction, the UAV patrol and evaluation program, including checklist method and special program fault tree analysis method, is established to conduct qualitative and quantitative analysis of the construction sites. Finally, according to the actual application results, the effectiveness of UAV patrol is evaluated in terms of inspection time and cost saving, safety risk mitigation, compensation reduction, and environmental protection improvement. It is proved that UAV patrol used in grid construction can broaden the scope of construction management, reduce on-site construction control loopholes, lower on-site management risks, and improve working efficiency.
