Capacidad dinámica de transporte en líneas eléctricas aéreas. Métodos de monitorización y aplicación en campo

Abstract

This paper presents different methods for overhead

transmission line monitoring and the calculation of dynamic

line rating. Some of these techniques are based on the

reading or the prediction of the whole set of meteorological

variables involved in the corresponding equations, whereas

other methods use direct or indirect measurements of the

conductor temperature. Additionally, a correction method will

be described for incomplete monitoring situations. Finally, a

real case study is presented for a 220-kV overhead line, where

a double monitoring technique is considered for the calculation

of the dynamic line rating, with a remarkable improvement in

the utilization of the assets, compared to the seasonal rating.
