Experimental validation of ultra-shortened 3D finite element electromagnetic modeling of three-core armored cables at power frequency
(Elsevier, 2022-02)
Due to recent advances, the numerical analysis of submarine three-core armored cables can nowadays be developed through the finite element method (FEM) in a small slice of the cable. This strongly reduces the computational ...

A Thermal Model for Three-Core Armored Submarine Cables Based on Distributed Temperature Sensing
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-06)
This paper presents a procedure for the derivation of an equivalent thermal network-based model applied to three-core armored submarine cables. The heat losses of the different metallic cable parts are represented as a ...

Direct torque control of multiphase doubly converter-fed asynchronous machines incorporating the harmonic torques
(ASTES Publishers, 2018)
Doubly fed asynchronous machines have an outstanding property: they can be operated up to twice rated speed delivering full rated torque. This paper presents, for the first time in the literature, a control system for ...

Towards a New Model of Evaluation of Transformation Losses in Solar Orchards
(European Association for the Development of Renewable Energies, Environment and Power Quality, 2007)
In this article is analyzed the economic yield that would turn out from replacing the conventional transformers currently used on solar orchards by others of higher performance. In this way, the losses would be ...

Hybrid 2D/3D fully coupled electrothermal model for three-core submarine armored cables
(COMSOL, 2020)
The computation of the power losses in submarine three-core lead sheathed armored cables is overestimated by the IEC 60287 standard, and hence its size and cost. 3D finite element simulations in COMSOL Multiphysics have ...

Use of 3D-FEM Tools to Improve Loss Allocation in Three-Core Armored Cables
(MDPI, 2021-04)
Loss allocation through analytical expressions in three-core lead-sheathed armored cables is challenging due to the complex geometry of this type of cable, commonly employed in submarine energy transmission systems (involving ...

Characterizing the Steady-State Performance of AC Lines Through a Dimensionless Universal Model
(IEEE, 2022-04)
This paper revisits the AC power line model. Based solely on three dimensionless parameters, a universal electrical model is first developed, which is valid for any kind of power line (overhead, underground/submarine or ...
