Dynamic capacity rating for wind cooled overhead lines

This paper shows that with presently applied static capacity rating for overhead lines there is a high unutilized capacity a large percentage of the time. The possibility for applying dynamic line rating in order to reduce or postpone reinforcements of overhead lines using weather measurements in the power line corridor and thus not causing delays for the wind power planners is assessed in this paper. Very few occasions of low wind cooling in the power line corridor at the same time as high wind at nacelle height have been observed.
