Modeling and fault detection of electric power system
 Kluz, Jan ; Huzlík, Rostislav (referee) ; Vlach, Radek (advisor)
Thesis focuses on the topic of fault detection of power systems. First part presents a comprehensive review of area of reactive, preventive and predictive maintenace of power systems based on physical or AI–driven models. Important part is design and subsequent assembly of an experimental testing device. This device incorporates four faults: heightened contact resistance, low contact area, parallel load imbalance and sparking. Device contains precise current and linear Hall sensors. The device has successfully been assembled and tested with positive results. A lumped parameter thermal networks has been created on this experimental device and results were verified with measured data. Thesis also contains statistical analysis of voltage and current signals, that were captured during spark discharges with 10 – 90 voltage supply.
