大范围电网山火灾害“星地空”立体防控体系建设及应用

Construction and application of prevention and control system for massive wildfire near transmission line by coordinated helicopter,satellite and ground equipment

山火是危及电网安全运行的严重灾害。电网发生山火时,处置时限性要求极高,为提升电网山火的处置效率,构建"预测提前部署—卫星广域、空中机载巡查及时发现—空地联动灭火"的山火立体防治体系:研制直升机监测、通讯和灭火一体化装置,实现直升机监测、应急会商与灭火快速联动,携带直升机灭火装备巡查山火,发现山火快速灭火。实践中,该体系已扑灭现场危及电网安全运行的山火80余处,应用表明:直升机灭火装备40 min内灭火距离达100 km。

Wildfires near transmission lines seriously threat the power grid security. When the wildfire near transmission lines occures, it should be put out immediately. In order to promote the disposal efficiency of wildfires, a stereoscopic control system was proposed, which can predict wildfire to deployment fire-fighting equipment in advance, detect the wildfire in time by the airborne monitoring device and fight the wildfire combining air and ground. The integrated device with wildfire monitoring, communication and fire extinguishing was designed, which can realize the rapid linkage of helicopter monitoring, emergency consultation and fire-fighting. Fire-fighting equipment was carried to inspect wildfires and extinguish the wildfires quickly.The system had extinguished more than 80 wildfires that endanger the safe operation of the power grid. The application shows that the helicopter fire extinguishing equipment can put out 100 km wildfire within 40 minutes.
