Dynamic Line Rating Protection for Wind Farm Connections

This paper describes how dynamic line rating is applied for load management and protection of a 132 kV line between Skegness and Boston (North East of England) thereby enabling a larger penetration of wind generation. The rating of the line is calculated dynamically from local weather measurements to co-ordinate allowed generation automatically. As a back-up system, in case for some reason the wind farm power output is not reduced on command by the control system, it is proposed that a relay will initiate tripping of wind generators.
