6. Transmission line protection performance in presence of power electronic-interfaced devices : Impact and needed countermeasures in the Swedish transmission system
University essay from Uppsala universitet/ElektricitetsläraAbstract : The penetration level of power electronic-interfaced devices (PEID:s) in power systems isincreasing, including wind- and solar power, HVDC and FACTS devices. Fault current injectedby PEID:s is lower in magnitude, may lack or contain a reduced negative sequence componentand can have a wide range of phase angles, as opposed to fault current supplied bysynchronous generators (SG:s).

7. Gearbox fault detection, based on Machine Learning of multiple sensors
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : The increasing demand for higher efficiency and lower environmental impact of transmissions, used in automotive and wind energy industries has created a need for more advanced technical solutions to fulfil those requirements. Condition monitoring plays an important role in the transmission life cycle, saving resources and time. READ MORE

8. Smart components : Creating a competitive edge through smart connected drive train on mining machines
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : Major drivetrain components of the Epiroc machines like axles, gearboxes, transmission, torqueconverter, clutch, and bearings are critical components which are focused upon in this thesis. Failure of these major component results in breakdown of the vehicle and if early fault detection is not existing, then this causes engineers and technicians to spend a substantial amount of time to identify the root cause of the failure.

9. Resonant overvoltages caused by transformer energization and saturation : Two EMT case studies conducted using models of the grid in Stockholm and an off-shore wind farm
University essay from Uppsala universitet/ElektricitetsläraAbstract : This thesis investigates the impact of resonant overvoltages and their origin. Series and parallel resonances are present in any electrical grid. The frequency of which this resonance occurs is called resonance frequency. READ MORE

10. Large Scale Analysis of Massive Deployment of Converter-based Generation equipped with Grid- forming Strategies
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : To mitigate the carbon footprint and the need to fulfil the energy goals in terms of sustainability, it is required to deploy a large integration of green energies. Therefore, in the previous and the coming years, there will be a high research and technological interest in the high penetration of converter-based generation. READ MORE
