Abstract

The design ice thickness for the ultra-high voltage DC lines in ultra-heavy ice zones may arrives at 60 mm~80 mm, and isolated-span lines are usually employed. In this paper, the finite element models of the ultra-high voltage DC lines in ultra-heavy ice zones are set up, the dynamic responses of the lines with different span length, elevation difference ratio under different ice thickness, ice-shedding rate and wind speed are numerically simulated, and the dynamic response characteristics are analyzed. The conductor jump height envelop, transverse swing amplitude and axial unbalanced tension are defined. Combining the numerical simulations and the BP neural network algorithm, the prediction models for the dynamic response parameters with span length, elevation difference ratio, ice thickness, ice-shedding rate and wind speed as input are established. The prediction models provide instruction for the tower head design of the ultra-high voltage DC lines in ultra-heavy ice zones.

Key words
