Research on Wind Disaster Risk Assessment of Transmission and Distribution Lines

Based on the 10-year wind speed data, geographic data and grid data of Fujian Province, a wind disaster model of transmission and distribution lines including disaster-causing factor, disaster-embedded environment, disaster-bearing body and anti-disaster capability, is established. The geographical information system (GIS) technology is used to vectorize the wind disaster risk index of the transmission and distribution lines, and the distribution map of the wind disaster risk index based on the map of Fujian Province is obtained. The results show that the risk of wind disasters from coastal to inland is gradually decreasing. The risks from Fuzhou to Ningde and Xiamen to Quanzhou are the highest, and the maximum disaster index is 0.69 in Fuzhou.
