Fast and accurate cable fault localization using sensors integrated into cable ends and/or joints KU Leuven
This project focuses on developing sensors possibly integrated into a HVDC cable joint, for use in an online and/or offline fault localization measurement. By using measurements integrated into the cable joint, we are able to achieve a higher fault localization accuracy compared to measurements at the cable end given that attenuation and distortion of the wavefronts will be lower. Furthermore, it puts no special requirements on the location ...
Fault detection and diagnosis in bearings and gears using fiber-optic sensors KU Leuven
Bearings and gears are critical machine components for many applications. For that reason, a plethora of methodologies have been proposed for monitoring their operational condition. Most methodologies are focused on indirect measurements, with the sensors being mounted away from the critical components, especially in complicated structures. This often results in lack of accuracy, robustness and interpretability of the measurements but also ...
Deterministic seismic hazard assessment in the Belgian Campine basin at the Mol/Dessel site: From seismic source to site effect KU Leuven
The objective of this PhD is to perform a deterministic seismic hazard assessment in comparison with existing probabilistic hazard assessments for the specific case of the Mol-Dessel site, which comprises different nuclear industries. In the rare case of a large earthquake, these might pose a threat to population and environment.
The expected results will consist in ground motion response spectra at the ground surface of the Mol-Dessel ...
A Methodological Approach to Short Circuit Protection for Low Voltage DC Grids KU Leuven
This thesis aspires to contribute to the technical and regulatory knowledge on LVDC protection that is necessary for a breakthrough of LVDC grids. To this end, the operation of an LVDC grid in normal and fault conditions was analysed extensively. This revealed that a major obstacle for the widespread implementation of LVDC grids is the need for consistent, universally adopted methodologies for the development of their protection, especially ...
Machine learning for failure identification and reliable mitigation of rotor eccentricity in electrical drives KU Leuven
Mechanical vibrations are the curse of electrically driven mechatronic systems, like robots, autonomous vehicles. They cause those systems to degrade and result in lower-quality processes and products, higher costs, more extended system downtimes and reduced reliability. Studies show that on average 5 % of production capacity is lost due to unplanned shutdowns, of which nearly half (46 %) are the result of mechanical failures (source: Marsh ...
Protection of future distribution grids KU Leuven
The integration of renewable energy resources in the distribution grids and transmission lines will change the fault level and produce a current waveforms that are significantly different from those of traditional synchronous or asynchronous generators. Short circuit level and fault current behavior are pre-assumption of most existing protection schemes. Therefore, the design and adaptation of the protection scheme are essential for reliable ...
Realizing safe and stable bipolar low-voltage DC power and data backbones KU Leuven
The project aims to define the essential network code and to realize the hardware and software to enable a stable and safe bipolar DC power and data backbone for industrial, commercial and residential areas. These are demonstrated and validated in a 100 kW bipolar +/- 350 ... 380 V DC test installation. The network code is intended as a guideline for bipolar DC micro grids and will be shared with international standardization ...
