A three-dimensional finite element model of a 500 kV high-voltage transmission tower-line coupling system is built using ANSYS software and verified with field-measured data. The dynamic responses the under different wind speeds directions are analyzed compared design code. results indicate that speed plays an important role in effect. Under low speed, effect less obvious can be neglected. With increased on tower gradually becomes prominent, possibly resulting risk premature failure system....
According to a generalized Hamilton’s principle, three‐dimensional (3D) nonlinear vibration equations for overhead transmission lines that consider geometric nonlinearity are established. Based on the characteristics of an actual line, 3D simplified two‐dimensional equations, and behavior is investigated by combining theoretical analysis with numerical simulation. The results show have inherently characteristics. When in free vibration, line can undergo internal resonance, even when its...
