Evaluation and Comparison of Power Quality Changes from Multiple Measured Points
Koštialik, Marek ; Kopička, Marek (referee) ; Paar, Martin (advisor)
This diploma thesis deal with the description of electrical energy quality in low voltage. A test data model is created in the thesis which can automatically evaluate the state of the quality of electric energy in terms of higher harmonic voltages in the MATLAB programming environment. To verify the correct design of the model, two possible views of simulated data are created in the form of tables and graphical dependencies. An user interface is created for more complex control of each model states of the data being considered.

Voltage profile regulation in Low-Voltage distribution systems
Koštialik, Marek ; Kopička, Marek (referee) ; Drápela, Jiří (advisor)
This paper deals with controlling the voltage profile in low voltage distribution networks. In the first part of the theoretical analysis is the solution view of inadequate elimination connecting renewable energy sources on distribution network. Subsequently, in a published review of factors representing the power quality in LV. The second part is a detailed search of the individual voltage regulators in consideration their specific solvability in LV. In the practical part will followed by the selection and realization of serial voltage regulator and consequently it´s experimental verification functions in low-voltage network.
