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

Abstract

En este artículo se presentan diferentes métodos para la monitorización y el cálculo de la capacidad dinámica de transporte (DLR) en líneas aéreas, distinguiendo los basados en la medición o predicción de todas las variables meteorológicas involucradas en las correspondientes ecuaciones, y los que emplean medidas directas o indirectas de la temperatura del conductor. Además, se describirá un método de corrección para los casos en los que exista una monitorización incompleta de la línea bajo estudio. Finalmente se presentará un caso real de estudio en una línea de 220 kV, donde se aplicará un sistema de doble monitorización para el cálculo del DLR, obteniendo mejoras considerables en el aprovechamiento de las líneas, comparado con el uso de capacidad estacional.

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.
