Abstract

The invention discloses a method for identifying hidden dangers of flood faults in power transmission towers based on SAR images. The identification method includes the following steps: step 1: filter the SAR image; step 2: use a threshold algorithm to extract the binary image of the water body area of ​​the SAR image ; Step 3: Using the tower center distance search algorithm and the tower base grid distance search algorithm, calculate the shortest distance from the tower to the flood area and the proportion of flood in the search area; Step 4: Based on the distance from the tower to the flood and the flood within the range of the tower Calculate the flood hazard coefficient according to the proportion, and judge the disaster situation of the tower.

Description

technical field [0001] The invention relates to the technical field of natural disaster event monitoring in electric power systems, in particular to a method for identifying hidden dangers of flood faults in power transmission towers based on SAR images. Background technique [0002] With the increase of power grid scale, the probability of power grid encountering sudden disasters is also increasing. Among the losses caused by various natural disasters in the world, flood disasters account for as high as 40%. In recent years, major flood events have caused high economic losses. Floods have washed away the foundations of transmission towers, resulting in disconnection of towers and submersion of power facilities, resulting in power supply interruptions and threatening power. The safe and stable operation of the system will bring huge losses to people's life and production. If the hidden danger of flood failure of the transmission line can be discovered in time, and the trans...
