 A multi-model online comprehensive calculation method for wind pressure of transmission lines caused by tropical cyclones, using the tropical cyclone meteorological information regularly released by the Meteorological Center, including the latitude and longitude coordinates of the center of the tropical cyclone, the maximum wind speed V max , Grade 7 wind circle radius R 7 and 10-level wind circle radius R 10 Information, a four-layer nested iterative structure including the outermost layer, the innermost layer, the second inner layer, and the second inner layer is designed. The specific implementation process is as follows:
 like figure 1 As shown, the outermost layer structure: According to the real-time information of the typhoon path released by the box , the box  judges whether to start, end or wait for the multi-model comprehensive parameter identification and transmission line wind pressure calculation function module;

 Tropical Cyclone No. 11 in 2012 "Hai Kui" entered the eastern part of the East my country Sea at 17:00 on August 5 and strengthened into a severe tropical storm. It landed in Xiangshan County, Zhejiang Province at 3:00 on the 8th, with a maximum wind force of 14 class. Select the meteorological data of "Sea Anemone" in some time periods (from 22:00 on the 7th to 8:00 on the 8th) to calculate the changes in the wind pressure on the overhead transmission lines around it during its movement, and compare it with the design value of the line wind pressure Compare to identify whether the line may be damaged. The relevant meteorological data of tropical cyclone "Hai Anemone" are shown in Table 3.
 Table 3 Data of Tropical Cyclone "Hai Anemone"
 The maximum wind speed radius R identified independently by a single model and comprehensively identified by multiple models max Listed in Table 4. Table 5 shows the calculation results of the weight coeff...
