  1. Alternative energy systems in the concept of sustainability

    The topic is focused on energy systems that offer high sustainability potential. The acquisition of energy will still be the focus of modern society, and with the development of technologies, it is clear that the current concept will need to be significantly modified towards renewable resources. However, the renewable resource is not the only condition. Future technology will necessarily evolve with regard to material recovery and very low maintenance costs. However, it is not possible to rely only on technologies already produced such as wind or photovoltaic power plants. Great potential is offered by biomass, but not in the form of direct combustion but using biodegradation processes. Very resonant technology, based on the optimization of energy flow and minimization of transmission losses, is a very interesting and not very scientifically researched area. It is not only electromagnetic resonance but also mechanical only at the molecular or atomic level. A significant part of the work should therefore be devoted to the shape configuration of the power equipment and its influence on the resulting parameters. In this section, the greatest experimental benefit is expected.

  3. Comprehensive lighting systems in a sustainable concept

    Lighting technology is experiencing a further stormy development period, as we have very efficient light sources, very sophisticated control technology and technology to develop virtually any luminaire. At first glance, a well-researched area of ​​physiology of visual perception has now significantly expanded discoveries in the area of ​​light influence on humans in the area of ​​biological processes. The influence of light has been demonstrated to a molecular level and this important fact can not be ignored in future technologies. At the same time, however, extreme pressure on energy savings and the search for ways to reduce the energy demands of buildings is emerging, which is also avoided by lighting techniques. The topic of doctoral work will therefore address these seemingly contradictory demands and look for ways to meet both requirements at once. Lighting technologies will have to respect not only energy but also material and environmental issues. These aspects will also be addressed in the work. The outcome of the work should be a new vision for lighting technology that motivates both manufacturers and users to focus more on long-term perspective solutions, rather than on short-term economic ones.

  6. 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.

  17. 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.

  7. Non-traditional resonant and quasi-resonant DC/DC converters with transformer.

    The soft-switching techniques of DC/DC converters enable to eliminate switching losses. Then the switching frequency can be increased without decreasing the converter efficiency. The high switching frequency is highly desired since it enables reducing of dimensions, mass and volume of wound converter components (coils, transformers). Further using the progressive technology SiC the switching frequency can be increased much more. The resonant principle can be advantageously used in the DC/DC converter with a high output voltage (resonant compensation of parasitic capacities) or in the devices for a wireless (inductive) energy transfer. A limited controllability of resonant converters is a substantial problem of resonant converters. Its elimination will be one of the most important tasks of this work.

  9. The VVER spent nuclear fuel characterization

    Spent nuclear fuel parameters like residual heat generation, neutron or gamma emission or reactivity, are very important information, which has completely been defined by nuclear fuel inventory. Spent nuclear fuel inventory means a vector of nuclear fuel nuclide concentration, especially fission products, activation products, and decay products. Such data together with fuel history, initial enrichment and/or initial burnup absorbers concentration, define physical quantity called burn-up (mean assembly burn-up; fuel rod burn-up; etc.). Burn-up values for core off-loaded and/or stored fuel assemblies are calculated using reactor-physics codes; as well as other parameters of spent fuel, like inventory. However, experimental verification of calculated values is very difficult and requires complex utilization of passive and active detection methods and simulated values. Investigation of experimental methods of spent nuclear fuel characterization as well as simulation is the main task for a PhD candidate registered to the topic. Resulted methodology would be utilized by safeguards or by authorities responsible for long term storage and/or final repositories of spent nuclear fuel. Doctoral research will be supported by the internship at foreign research institution.

  10. The VVER spent nuclear fuel characterization

    Spent nuclear fuel parameters like residual heat generation, neutron or gamma emission or reactivity, are very important information, which has completely been defined by nuclear fuel inventory. Spent nuclear fuel inventory means a vector of nuclear fuel nuclide concentration, especially fission products, activation products, and decay products. Such data together with fuel history, initial enrichment and/or initial burnup absorbers concentration, define physical quantity called burn-up (mean assembly burn-up; fuel rod burn-up; etc.). Burn-up values for core off-loaded and/or stored fuel assemblies are calculated using reactor-physics codes; as well as other parameters of spent fuel, like inventory. However, experimental verification of calculated values is very difficult and requires complex utilization of passive and active detection methods and simulated values. Investigation of experimental methods of spent nuclear fuel characterization as well as simulation is the main task for a PhD candidate registered to the topic. Resulted methodology would be utilized by safeguards or by authorities responsible for long term storage and/or final repositories of spent nuclear fuel. Doctoral research will be supported by the internship at foreign research institution.

  11. Use of the cooperation of energy storage and renewable energy systems to support the distribution network operation

    The thesis is focused on the design and the development of a model representing the cooperation of battery and photovoltaic systems connected via hybrid inverters into the distribution network (DG). The main object of the research is to specify the possible use of this concept to support of the distribution network operation, i.e. voltage regulation, reactive power compensation, distribution congestion relief, asymmetry compensation, power microoutages limitation, backup source for crisis management, distribution capacity compensation, etc. Research results are the definition and the establishment of criteria for the inverter management and for using of this concept within the system network services at level of low and medium voltages. The research is also targeted on the identification and the development of other new possibilities for DG operation supporting.
