The aim of this TB is to serve as a practical guide for preparing models and performing studies necessary during the assessment of the technical performance of HV/EHV systems with a large share of (long) AC cables with a nominal voltage of 72.5 kV and higher. The brochure is particularly focused on the differences in the technical performance of an electric power system with long AC cables as compared to one with AC overhead lines. These differences in performance are due to the different electrical properties of AC cables as compared to OHLs. To interpret the results of studies and identify how they are affected by the distinctive characteristics of the cable, it is necessary to be familiar with the characteristics of various cable models in terms of their performance and resultant range of applicability, the effect of input data and their practical availability at various study phases, and the effect of physical properties of cables on their electrical performance. The reader is provided with some essential information about requirements for cable models for system technical performance studies over a range of frequencies. This ranges from data gathering to model accuracy, effect of data on model performance, evaluation of available cable models and their applicability for various studies, methods of validation, etc.

Abstract
The aim of this TB is to serve as a practical guide for preparing models and performing studies necessary during the assessment of the technical performance of HV/EHV systems with a large share of (long) AC cables with a nominal voltage of 72.5 kV and higher. The brochure is particularly focused on the differences in the technical performance of an electric power system with long AC cables as compared to one with AC overhead lines. These differences in performance are due to the different electrical properties of AC cables as compared to OHLs. To interpret the results of studies and identify how they are affected by the distinctive characteristics of the cable, it is necessary to be familiar with the characteristics of various cable models in terms of their performance and resultant range of applicability, the effect of input data and their practical availability at various study phases, and the effect of physical properties of cables on their electrical performance. The reader is provided with some essential information about requirements for cable models for system technical performance studies over a range of frequencies. This ranges from data gathering to model accuracy, effect of data on model performance, evaluation of available cable models and their applicability for various studies, methods of validation, etc.Pubblicazioni consigliate
