Abstract:

This paper presented the rendering method of galloping distribution map for transmission line based on the meteorological-geographical method following the frequency method and the galloping coefficient method. Based on the statistics and analysis on the icing galloping conditions of transmission line over the years, the meteorological model and geographical model were built for icing galloping, through the summary of meteorological and topographic features, laws. In combination with operation experience, galloping area partition and classification standard were put forward. The standard technical system of rendering method for galloping distribution map was established. Finally, this paper used the meteorological-geographical method to draw the galloping distribution map for some province, and inspected its matching with the actual situation, which could conclude that the method was reasonable and correct.

Key words: transmission line galloping, meteorological-geographical model, render the galloping distribution map
