摘要：
It has always been a hotspot in the field of transmission engineering to study the wind-induced response of transmission tower-line system and improve the wind-fighting defense capability of transmission lines. Establishing accurate finite element models and wind speed simulation methods is the key to the research. A finite element analysis method of high-voltage transmission considering tower-line coupling factor was introduced firstly. Then the wind speed simulation method and wind-induced response analysis method taking spatial-temporal distribution of wind speed into consideration, based on linear shift transform, were discussed in detail, compared with the traditional research. Finally, one typical 220kV transmission line was chosen as an example to compare the wind-induced response of transmission lines with a comprehensive consideration of tower-line coupling factor and spatial-temporal distribution correlation of wind speed, and four key parameters such as axial force and displacement of the lowest sag point along the transmission lines, axial force of suspension point and displacement of the tower head were calculated and discussed contrastively. © 2019 Chin.
