Diagnostics and measurement in the high voltage systems
- Branch of study: Electrical Engineering and Communications
- Department: Department of Electrical Power Engineering
-
Description:
The topic deals with advanced diagnostic methods for electric power equipment insulation systems, e.g. frequency response analysis, dielectric spectroscopy and partial discharges. The topic also covers operation monitoring of key parameters and transient phenomena. This monitoring is based on high precision measurement of ultra high voltage and high current in wide frequency range. The research focus on advanced sensors and measurement systems in electrical power networks. Diagnostics and monitoring systems results are used to determine component state.

Integration of Renewables and Electricity Storage Technologies into Power Systems
- Branch of study: Electrical Engineering and Communications
- Department: Department of Electrotechnology
-
Description:
The topic focuses on innovative simulation models of power systems and individual components, with a specific emphasis on the integration of renewable energy sources and prospective storage elements. The aim is to achieve the highest possible reliability and stability of electricity supply. This involves conducting experimental measurements, evaluating observed data, and modeling transients of complex and hybrid power systems. The ultimate goal is to extend these models to a macroscopic scale, incorporating selected technologies. Additionally, the research includes optimization of parameters, operating characteristics, and factors affecting the lifetime of individual components, while considering the requirements of the upstream networks.
