Voltage magnitude deviations in a low-voltage distribution network due to increase in impedance of Y-connected load node to ground and unbalanced load
 Blažek, Ondřej ; Paar, Martin (referee) ; Drápela, Jiří (advisor)
This work deals with the issue of an unbalanced power load of a three-phase main load and the associated network load of a PEN conductor. The introduction discusses the various types of systems where the distribution networks are implemented. Followed by the description of network segments causing issues discussed in this paper. The theoretical part discusses the possible operating conditions which lead to balancing the flow of neutral current, also shows the relation of the size of countervailing power charges and the form of the network load. There are also hints of possible risks that the mentioned situations may cause to the network operation in terms of function and safety. The practical part deals with the mathematical simulation model created in MATLAB. There are simulations based on which there is a description of the network behavior for the cases of induced adverse factors. The conclusion summarizes the most important results and findings produced by the simulations.
