Classification Method of Galloping Region for Transmission Lines

Abstract:

Transmission line gallopingis self-excited vibration of iced conductor with low frequency and largeamplitude, the countries almost all over the world have occurred transmissionline galloping, which caused a great economic loss. Drawing the effectivedistribution map for galloping plays an important role in guiding theanti-galloping design, the key of this work is to establish a scientific methodfor galloping region division. In this paper, several methods for gallopingregion division were introduced: frequency method, coefficient method andmeteorological-geographical method. This paper also compared the applicabilityof various methods and their advantages and disadvantages. It shows that themeteorological-geographical method is the best choice for us to dividegalloping region at the present time. However, in the practical application, weshould take all the applicability of the three methods into consideration toget a reasonable division for galloping region.
