Due to economical and political trends, in the Netherlands the electricity produced by distributed generation units has increased significantly. From 2004 on in the Stedin area, three large greenhouse areas have been developed. In each greenhouse a CHP-plant is installed and as a DSO Stedin saw the number of new CHP-plant connections in its MV grid increasing. Legal rules oblige Stedin to connect CHP-plants in a much shorter time frame than normal project times for necessary grid extensions. This leads to a major grid planning problem, especially when a grid extension of the transmission grid is involved.

This paper describes how dynamic line rating(DLR) is applied for load management and protection of a 132kV doublecircuit 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, a relay is available to initiate tripping of the wind generators. The paper also includes an analysis of the field data gathered from site which is used to verify the accuracy of the relay algorithm.
