Lafuente Arjona, Oscar (author)Military ground vehicles require protection against ballistic threats encountered in the battlefield. Traditionally used armour steel dramatically increases the weight of a vehicle, decreasing its mobility and hampering its capability of carrying payload. The development of new material and protection concepts, namely non-metallic armours, that...master thesis 2023

Bakhshi, Ali (author), Bigdeli, Mehdi (author), Behdani, B. (author), Hojabri, Mojgan (author)Ferroresonance, as an undesirable disturbance, leads to significant overvoltage and distorted waveforms. This phenomenon can be highly damaging to voltage transformers and other parallel-connected equipment and can entail catastrophic consequences. This paper aims to design and study a solid-state ferroresonance-suppressing circuit (SSFSC) to...journal article 2023

Heidary, Amir (author), Ghaffarian Niasar, M. (author), Popov, M. (author), Lekić, A. (author)Due to the extension of the power grid with many complex and compact pieces of power equipment, transformers will be more exposed to fast transient, resulting from various resonance conditions. Transformer resonance can result in severe overvoltage on internal parts of the winding, leading to insulation failure and, consequently, transformer...journal article 2023

KOUROS, Michail (author)To ensure a safe power system which operates correctly, a proper grounding system is necessary to provide connections to the ground at specific points. A grounding system is generally designed: (1) to reduce voltages occurring in the grounding system for short circuit situations (at power frequency) to an acceptable level in terms of step and...master thesis 2020

Rivera Diez, Laura (author)The electrical infrastructure is evolving, shifting into a decentralized grid that allows the incorporation of renewable energies and mitigates the negative effects of power outages. It is predicted that this will lead to a substantial increase in the amount of microgrids deployed worldwide. Especially in locationswith a less reliable grid, the...master thesis 2020

Peyghami, S. (author), Palensky, P. (author), Blaabjerg, Frede (author)Renewable energy resources are becoming the dominating element in power systems. Along with de-carbonization, they transform power systems into a more distributed, autonomous, bottom-up style one. We speak of Smart Grid and Microgrid when distributed energy resources take over. While being a means to improve technical and financial efficiency,...journal article 2020

Liu, Lian (author), Liu, Zhou (author), Popov, M. (author), Palensky, P. (author), van der Meijden, M.A.M.M. (author)HVDC technologies are widely acknowledged as one of solutions for the interconnection of renewable energy resources with the main electric power grid. The application of the latest modular multi-level converter (MMC) makes power conversion much more efficient. Due to the relatively low impedance in a DC system, DC fault currents may rise to an...journal article 2020

van den Berg, Mario (author)Design criteria for the stability of rock filters on river beds (i.e. rock bed protection) are extensively researched and successfully applied in practice. The most common stability criteria are the Izbash and Shields criteria. These methods define a critical flow (Izbash) or parameter (Shields). Rijkswaterstaat (RWS) wants to explore a more...master thesis 2019

de Jong, Sander (author), Knoester, Ferdi (author), Alferink, Christian (author), Quast, Arnout (author), Smits, Misiu (author)The beach adjacent to the Tasikoki Wildlife Rescue and Education Centre is one of the many beaches worldwide suffering from coastline recession. This loss of coast has a negative impact on the environment, local society and ecology. In general, shoreline retreat is caused by sea level rise (SLR) and erosion. The main objective of this research...student report 2019

Verhaert, Danilo (author)Tock is an embedded operating system that can run multiple concurrent, mutually distrustful processes, concurrently. Tock is written in Rust, a novel system programming language enforcing type safety at compile-time, and takes advantage of Rust's strong safety features. However, since Tock allows user-level applications to be written in any...master thesis 2018

Mackay, L.J. (author)The traditional ac power system is challenged by emerging distributed renewable energy sources and an increase in installed load capacity, e.g., electric vehicles. Most of these new resources use inherently dc as do more and more appliances. This poses the question, if they should still be connected on ac in the low voltage grid, which was...doctoral thesis 2018

Papadakis, Haris (author)Nowadays there is a movement towards the creation of HVDC grids. The massive integration of renewable energy sources, the operation of the current grid close to its limits and the need to facilitate the power trade are some of the reasons driving the research on HVDC grids. Towards HVDC grids, there are still some obstacles and technical...master thesis 2017
