The invention discloses a power distribution network disaster damage situation sensing method and
system based on emergency communication under rainfall flood. The method comprises the following steps: establishing a power distribution network disaster damage situation sensing model under urban rainstorm waterlogging; constructing a communication working point
site selection model, and determining possible parking points of the mobile unmanned aerial vehicle
station and the emergency communication vehicle; based on possible stop points of the mobile unmanned aerial vehicle
station and the emergency communication vehicle, considering path constraint and time constraint, determining a scheduling scheme and a transfer path of the mobile unmanned aerial vehicle
station and the emergency communication vehicle, and constructing a vehicle-aircraft cooperative communication
recovery model; and based on the constructed power distribution network disaster damage situation
perception model under the urban rainstorm waterlogging and the constructed vehicle-
machine cooperative communication
recovery model, constructing a power distribution network disaster damage situation
perception improvement model under the urban rainstorm waterlogging, and solving the power distribution network disaster damage situation
perception improvement model under the urban rainstorm waterlogging to obtain a situation perception improvement strategy. The disaster damage situation sensing capability of the power distribution network is improved, and rapid
recovery of the power distribution network after the disaster is realized.
