Galloping Characteristics of 10kV Overhead Transmission Line Using Finite Element Analysis Method

10kV overhead transmission lines are easy to be affected by severe weather conditions such as strong wind and icing, which is prone to galloping fault. This seriously affects the safety and reliability of distribution network. For the galloping characteristics of 10kV overhead transmission line in severe weather conditions, ANSYS finite element analysis software is used for simulation calculations. The static and dynamic characteristics of overhead line under different conditions are obtained. The simulation results show that the deformation of overhead line is not only related to the wind level, but also the direction of wind blowing to the overhead line. The main reason for galloping of the overhead line is the wind load. Icing makes the galloping characteristics of overhead lines more obvious, but the galloping of overhead lines may still occur when there is no ice. The conclusion of this simulation is helpful to grasp the operation characteristics of 10kV overhead transmission lines in severe weather (icing, strong wind). It also can provide reference for the design, on-line monitoring and early warning of the overhead lines.
