High-voltage cables - energy transfer carriers of the future cities
Abstract
The topic of this presentation is high-voltage underground power cables, that we use for the transmission and distribution of energy in urban areas. Today, power cables have become that invisible part of the network, which enables us to live in cities, regardless of whether we energize large commercial buildings, shopping centers, housing complexes or charging stations for electric vehicles. In this presentation, first of all, an overview of the current situation in the 110 kV transmission cable network in Serbia is given, with a special focus on Belgrade as the largest consumer. Examples show the types of used cables, which have been installed over time, as well as typical sections and expected powers that these cables can transmit. Given that the high reliability of the cable network is expected, the audience will be presented with a brief overview of the testing methods and the necessary technical conditions for performing the tests, which enable the assessment of the condition of the cable lines. The tendency to reduce losses in the transmission network and the limitation of existing raw materials for making cables, determined the development of new technologies and the application of superconductors as the future in this area. At the end of this presentation, new solutions in cable construction and their current application are briefly presented.
Keywords: High-voltage cables, Transmission, Network, City.
Biography of the presenter
Ninoslav Simic was born in 1974. in Drvar, where he finished primary school, after which he relocated to Sremska Mitrovica, in which he finished high school of Electrical Engineering ”Nikola Tesla”, in the field of automation and computer technology. He graduated from the Faculty of Electrical Engineering in Belgrade, in the energy department. He finished postgraduate studies in the same University in 2009. and obtained the title of Master’s Degree in Electrical Engineering, in the Department of Power Plants and Equipment. He gained his first experience in the power industry in 2000 at TE Ugljevik, and then in 2001 he became part of the team of the Institute Nikola Tesla in Belgrade, where he is still employed as a senior advisor. For more than 20 years, working in the field of technical maintenance and supervision, testing and research, and finally consulting and solving non-standard failures of high-voltage equipment, he had the privilege of gaining great experience and familiarity with the power system in more detail. Areas of interest: Analyzes of phenomena in the operation of power plants and equipment, transients, overvoltages, analysis of the causes of breakdowns and fires, cable lines, tests of power equipment, grounding systems and lightning protection, low-voltage electrical installations, thermographic tests of the magnetic core of generator stators and energy equipment that includes equipment of all powers and voltage levels from 0.4 kV to 400 kV. He is the author of a number of the most notable papers at the conferences of CIGRE and CIRED national committees in Serbia, Montenegro and Bosnia and Herzegovina. He is a member of the international organization CIGRE Paris, SC A3, secretary of the A3 CIGRE Serbia committee and chairman of commission N064 at the Institute for Standardization of Serbia.
