| Title: |
Galloping
Overhead Transmission Lines (Master's Thesis Presentation)
|
Abstract
|
In this
thesis, galloping of overhead transmission lines is studied. This is a
low frequency, large amplitude, wind-induced vibrations of both a
single and a bundle of overhead transmission lines. The model for this
phenomenon is derived from the first principles of Newton's and Hooke's
laws.
We analyze the model and develop an algorithm for solving the system.
We will present two numerical schemes, that have been chosen for this
task, namely the upwind and ADER schemes. Lastly, conduct several
galloping simulations under practically relevant conditions.
