Street, Hungary; email: szabo.david@vet.bme.hu AB - In order to adjust the electric power network to today’s trends—such as the charging of electric vehicles, design of the Internal Electricity Market (IEM), headway of renewable energy sources, etc.—the demand for flexible network solutions is increasingly significant. Dynamic line rating (DLR) technology offers a flexible solution for the uprating of overhead lines. Moreover, the DLR methodology can be used in a wider system approach in order to establish a line management system, including functions such as ice prevention subsystems or the real-time tracking of clearances. Therefore, the extension possibilities and operational features of DLR-based systems have been extensively researched in the last few years, which is also confirmed by the high number of pilot projects funded for research and development on the topic of DLR. The key question during the implementation of a DLR system is the obtainable operational safety of such a system. This mainly depends on the installation places of the field equipment and the accuracy of the line rating calculation models. The aim of this article is the comparison of the so far available international line rating calculation models and also to propose another way for the determination of the real-time line rating. Moreover, laboratory measurements and case studies are presented for the confirmation of the proposed model’s reliability.

AB - Upward lightning requires a distinct approach compared to downward (cloud-to-ground) lightning. Some lightning strikes are triggered by objects on the ground itself. The occurrence of such strikes depends on various factors, including the object’s geometric dimensions, structure, relative location within its environment, as well as the distribution and location of electrical charges within the thundercloud. This phenomenon takes place more and more often due to the spread of wind farms and higher buildings. In this article, simulation and calculation is carried out regarding the Gaisberg Tower in Austria which is actively used as a measurement and research site for lightning purposes. A finite element simulation is carried out to assess the electric field characteristics in the geometry. The close electric field measurement instruments are located 170 m away from the tower on an enclosure which must be considered during data analysis. The result of the created model is validated by former measurement data which confirms the arrangement of the model and creates the opportunity to directly transform the values of the electric field from the field mill to the tower during appropriate conditions.

AB - Dynamic line rating (DLR) is a cost-efficient method to increase transmission line transfer capacity. Its techno-economic advantages have already been presented in numerous scientific papers. At the same time, limited operational experience and financial calculations are available concerning such line monitoring projects. This paper aims to give a cost-benefit analysis of a DLR system. The costs and economic benefits of a pilot DLR project in Hungary support the theoretical concept. The paper discusses the financial indicators, capital and operating expenditures, and benefit elements in detail. The quantified and non-quantified benefits are handled separately. As a result of the calculation, it is possible to determine the viability of a DLR project. The paper's key finding is that a financially supported pilot DLR project can ensure both technical benefits and financial return on investment. © 2023 IEEE.
