“…As a starting point, the method uses the Neher McGrath [1] and IEC [2] standard equations, which have been verified in [12], and solves them by using a convex optimization algorithm that provides always convergent results. The convex optimization algorithm finds the ampacity of a fixed cable configuration and, thus, serves as a single iteration within an outer-level combinatorial optimization algorithm that attempts to find the best cable configuration, from the point of view of the total system ampacity.…”

This paper presents a method for configuring the locations of any number of cables, for the best total ampacity. The optimal configuration is determined through a proposed two-level optimization algorithm. At the outer level, a combinatorial optimization based on a genetic algorithm explores the different possible configurations. The performance of every configuration is evaluated according to its total ampacity, which is calculated by using a convex optimization algorithm. The convex optimization algorithm, which forms the inner level of the overall optimization procedure, is based on the barrier method. The proposed approach is tested for a duct bank installation containing 12 cables and 15 ducts, comprising two circuits and two cables per phase, and compared with a brute force method of considering all possible configurations. The proposed approach is also applied to an installation consisting of a single circuit inside a large magnetic steel casing.

“…Second, computational fluid dynamic (CFD) and finite element methods (FEM) can also be used to study this thermal balance and to recreate different types of conductors and operation and weather conditions [ 13 , 14 ] and finally, direct or indirect measurement methods of some line parameters can be used to estimate the temperature of the conductor [ 15 , 16 , 17 ]. All the previous methods were used to check the reliability of the infrared thermometer measurements.…”

Efficiency in power lines operation is becoming more crucial as the electrification increases and more renewable energies are connected into the grid. New methods and sensors are being added to create smart grids to face these challenges and conductor temperature sensors are one of them. Contact temperature sensors have several problems regarding safety and electronic damage due to the electromagnetic fields induced on the conductors. The goal of this paper is to describe an infrared temperature measurement sensor and to compare contact and non-contact temperature measurements to estimate the temperature of power lines. Measurements were done for almost a year, storing around 150,000 measures of contact and infrared thermometers for many different weather and load conditions. The results conclude that the infrared system can be successfully used to control the temperature of the overhead conductor within a range of less than 4 ∘C difference with respect to contact temperature methods for the 88% of the samples and less than 6 ∘C for the 99%.

“…Today, the greater majority of utilities and cable manufactures have been using the IEC standards based on the Neher-McGrath Model. An assessment on ampacity calculation has been presented comparing analytic and numerical methods [8]. IEC standards, steady-state (60287) and transient (60853), uses thermal model of power cable system included thermal resistances (T th ) and thermal capacitances (Q th ) similar to electrical circuits [9,10].…”

This paper presents a novel computer simulation program designed to aid teaching process in course of underground power cables for engineering students. The calculation of power cable ratings uses several different formulas and long analytical processes based on IEC 60287 and IEC 60853 standards. Therefore it is difficult to examine different variations such as power cable properties, installations and operation conditions, during the restrictive lesson time. For these reasons, a program has been developed to use for teaching process of the power cable course. The program allows the users to effectively learn the rating of underground power cables under different operation conditions with illustrative figures. The program details are presented and explained in this paper.
