Field Measurement Based PLS Model for Dynamic Rating of Overhead Lines in Wind Intensive Areas

Abstract

This paper presents results of lab tests, field measurements and mathematical modelling for the Dynamic Rating (DR) of Over Head Transmission Line (OHTL) in a wind intensive area. In this paper, DR is done by developing a statistical line model. This model is based on Partial Least Squares (PLS) multi regression. DR provides extra capacity to the line, over the traditional seasonal static rating, which makes it possible to defer the need for reinforcement the existing network or building new lines.
