Issued topics of Doctoral Study Program

2. round (applications submitted from 01.07.2019 to 31.07.2019)

  1. Conducted disturbances in power systems in audio-frequency range

    Increasing deployment of power converters in distribution systems leads to rise in high-frequency conducted disturbance level related to the converters switching frequencies. The switching disturbances occur dominantly in frequency range from 2 kHz to 150 kHz. Current experience shows that such disturbance may lead to serious malfunction of grid-connected sensing, measuring and/or controlling systems of analog or digital nature. At the same time there is significant gap in EMC coordination and standardization since the frequency range was for a long time out of interest. It is just between low-frequency disturbances connected to power quality and radio-frequency disturbance. The project is focused firstly on development of suitable measuring apparatus and procedure to monitor the disturbances in distribution systems in the audio-frequency range. Then origin and propagation of the disturbance should be studied and finally EMC concept is expected to be proposed. The theme takes a part of research project in cooperation with Czech utilities and with foreign universities (Germany, Italy). An intership at a foreign research institution, for instance TU Dresden, DE, is expected. Ask for more details at

  5. Chromatic flicker perception modeling in flickermeters

    Visible light variation may leads to disturbance of human’s visual perception. The origin of such negative effect is in the eye anatomy and physiology. The major influence on the flickering light perception can be found in eye viewing field, photoreceptors (cones of three types and rods) and their distribution at retina as a part of eye anatomy and in eye adaptation mechanisms like pupil, photo-chemical and neural adaptation (response) to luminous variations (including the photoreceptors spectral luminous efficiency) as a part of eye physiology. The human eye can be seen as specialized luminance multi-detector where the stimulation contrast is as important as radiant density. There are differentiated three types of flicker: temporal, spatial and chromatic. All of these flickers are joyless and may involve many psychological interactions. In artificially illuminated areas, lamps light variations due to variations in supply voltage may also lead to flicker perception. Such lamp possibly will produce light with time-varying radiant flux and its spectral distribution. The lamps flickering is produced by a voltage Phase Modulation (PM), mainly by Phase Jumps (PJ) and by Interharmonic Voltages (IH) superimposed on a voltage waveform. Thesis is focused on the voltage fluctuation to lamps time-varying radiant flux and its spectral distribution fluctuation transfer analysis and on the utilization of the analysis results for development and realization of an objective flickermeter having response to both the temporal luminance and chromatic flicker. The thesis aim is the realization of the new flickermeter types implemented in LabVIEW, with the experimental verification. The thesis covers theoretical-analytical, developmental and also practical-experimental part of study. An intership at a foreign research institution is expected. More information:

  6. Modeling of current interruption in electric fuses

    Electric fuses are protection elements widely used in low- and medium voltage power distribution networks. Fuses are typically designed to have fuse elements as segmented thin metal conductors that are embedded in silica sand. Due to over currents and short circuit currents the fuse elements are heated up and melted, an electric arc is ignited. Thus the mode of operation can be separated into a pre-arcing and a arcing phase. In the arcing phase the generated plasma is interacting with the filler medium (sand) and the fault energy is stored in the sand, leading to melting of the sand. The morphometric properties of the filler have an influence on the arc plasma, e.g. the plasma composition, thermodynamic and transport properties. The approach for this thesis is to first identify existing modeling approaches and evaluate from a numerical and result quality point of view. Starting point are existing arc models that are developed mainly for atmospheric gas discharge, but have limited validity in this application. As a second step a suitable model should be adopted or implemented and the identified model shortcomings should be addressed. The necessary transport, thermodynamic and absorption coefficients for the metal vapor and silica sand mixture need to be gathered. As a third step the model is applied to predict the interruption process for a specified fuse. By means of comparison of test results and simulation results the model accuracy and sensitivity is evaluated. This thesis will include close cooperation with Eaton. The student is expected to spend at least one month internship in Eaton.

  7. Modeling of switching arcs in mineral oil

    Mineral oil is used as an insulation medium in medium voltage power distribution equipment, like transformers or pad mount switchgear. In different applications switching is performed by means of electromechanical contacts that are submerged in mineral oil. During contact opening, an electric arc is formed and energy is transferred into the mineral oil, mainly by heat conduction and radiation. As a result, mineral oil is vaporized and gas bubbles are formed that are interacting with the oil. Close to current zero, the gas bubble starts collapsing since the energy input is decreasing. This will change the plasma conditions like pressure and temperature, which influences the plasma decay and therefore the dielectric recovery. The main goal of the thesis is to develop and implement a stable and performant multiphase flow solver in order to be able to simulate the complex interactions that occur during arc switching/arc interruption in mineral oil. This includes the modeling of phase change (oil  oil vapor) and determining the necessary thermodynamic, transport and radiation properties. Starting point are existing arc models that are developed mainly for atmospheric gas discharged, but have limited validity in this application. In a second step the processes during recovery should be investigated, since a prediction of successful interruption is determined by the rise of transient recovery voltage vs. dielectric recovery. In a third step the model accuracy and sensitivity is evaluated by comparison with actual test results. This thesis will include close cooperation with Eaton. The student is expected to spend at least one month internship in Eaton.

  8. Power system with electric energy accumulation

    Stability of electric power supply is - as a term - closely related with electrical energy production gained from renewable power sources (mainly from wind and photovoltaic power plants). The research will be focused on possibilities of accumulation of electric energy produced from renewable power sources with the help of modern technologies while focusing on hydrogen (VRB systems) utilization, accumulators based on Lithium and pumped storage hydro plants for its accumulation. The result of the work will be the draft measures in the energy system, which can solve time disproportion between electrical energy supply and take-off from the renewable power sources. The solution is connected with computer simulation (Matlab) and experimental measuring on a real model.

  10. The identification of power system faults

    Tutor: Toman Petr, doc. Ing., Ph.D.

  11. The voltage regulation in distribution networks with a high proportion of stochastic sources

    An increasing proportion of stochastic resources in networks affect the voltage stability during the day. Variable power delivery to the grid from these sources causes fluctuations in voltage variations during the daily diagram. Current devices used to the voltage regulation are unable to provide the required voltage level at all points of the network. The aim is to describe new possibilities and means for voltage regulation in distribution system and design concept of this regulation with regard to the current development of the resource base.

    Tutor: Mastný Petr, doc. Ing., Ph.D.

The example could be worse insulation state of transformers, grommets, single phase fault in line with covered conductors etc.
