Simulation of losses in LV cables due to nonlinear loads

Optimization of Spatial Configuration of Multi-Strand Cable Lines

“…• interesting conclusions may be arrived at when one analyzes the results illustrating the current non-uniformity for the lumped and dispersed triangular layouts, cf. It is straightforward to compute that the barycenter coordinates for each phase are then the same and they are equal to (5,10). It means that the proposed criterion for choosing the optimal spatial configuration is fulfilled in this case.…”

“…In some situations it is necessary to use multi-strand cables connected in parallel. Since 1957, the publication year of the seminal paper by Neher and McGrath [1], much attention was paid by the engineering community to the problems related to computations of current distribution in such systems [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Current distribution in multi-strand cable systems is uneven due to several factors, to mention skin and proximity effects related to strand geometry [3,5], the conditions of heat exchange with neighborhood [8,18,19], soil inhomogeneity, moisture, installation depth (if the cables are buried) harmonic spectrum of currents flowing through the cables [11], the presence of buried metal objects etc., to mention but a few.…”

“…Desmet et al [10] estimate that cable losses reach 5% of the total power consumption. On the other hand the infrastructure grid has to be re-designed constantly in order to adapt to new conditions resulting from installation of new distributed generating capacities like wind farms etc.…”

Метод Оцінки Втрат Потужності У Кабелях Низької Напруги Промислових Електричних Мереж

“…Процедури вибору кабеля для несинусоїдних режимів електричної мережі наведені в літературі [1][2][3][4][5][6][7]. В роботі [1] проаналізовано проблему додаткового нагрівання кабелів в системах електропостачання нелінійних навантажень.…”

Optimization of Spatial Configuration of Multistrand Cable Lines

“…At the same time, it should be stated that the problem is not merely a theoretical one; as pointed out by Čiegis et al [13], many existing power lines are overdimensioned by up to 60% in terms of transmitted power, which means additional costs and waste of deficit core material (e.g., copper). Desmet et al [14] estimate that cable losses reach 5% of the total power consumption. On the other hand, the infrastructure grid has to be redesigned constantly in order to adapt to new conditions resulting from installation of new distributed generating capacities like wind farms and so forth.…”
