Protection in electrical power system plays an important role in human and material safety during abnormal operating conditions. The heart of electrical protection system is the relay which senses abnormalities and commands the switches to break the circuit during a fault. Hence, optimization of protection parameters has gained paramount...

In deze thesis wordt het ontwerpproces van het Bachelor Afstudeer Project beschreven. De bedoe- ling van dit project is om een softwaresysteem te maken voor een oplaadstation voor elektrische fietsen. Het speciale aan dit oplaadstation is dat de fietsen voornamelijk opgeladen worden door energie opgewekt door zonnepanelen. Een gebruiker moet bij...

De opkomst van e-bikes doet de vraag naar oplaadpunten sterk toenemen. Hierbij speelt duurzaamheid een grote rol in de stroomvoorziening van deze oplaadpunten. Hierom wordt er op de TU Delft campus een oplaadstation gebouwd die zijn energie voornamelijk van zonnepanelen ontvangt. Dit zal een proeftuin zijn voor gelijksoortige toekomstige...

Power transformers are valuable assets in the power network, and have as the primary function to regulate the transmission and distribution voltage. A large amount of capital is required to manufacture, transport, install and maintain them. As the load in the network changes, the voltage needs to be regulated. Load change is the result of demand...

Silicon nanoparticles (NPs) embedded in a dielectric matrix, such as silicon oxide, pose a promising candidate for all-silicon multi-junction solar cells. This material is often analysed with photoluminescence (PL) measurements. In literature, the intensities of different PL measurements are either directly compared or normalized. Normalization...

Arguably the most important challenge of our time is climate change. In The Netherlands in 2014, 30% and 21.5% of total CO2 emissions were emitted by the electricity producing and transportation sector, respectively. Electric vehicles (EVs) have therefore gained interest as they do not emit carbon dioxide whilst driving and therefore do not...

Brushless doubly-fed induction generator (BDFIG) has the potential to replace current-popular doubly-fed induction generator in wind turbine market due to its higher stability and lower cost. The steady-state performance of BDFIG can be characterized by its equivalent circuit (EC). However precisely determining its equivalent circuit (EC)...

The traditional power grid map has drastically changed with the advent of renewable energy technologies. The intermittent nature of renewable energy sources hours. In order to deal with issues related to the fundamental quantities of a power grid system (frequency, voltage and current), smart grid systems have been introduced to ensure that...

The optical analysis of optically-textured and electrically-flat ultra-thin crystalline silicon (c-Si) slabs is presented. These slabs were endowed with decoupled front titanium-dioxide (TiO2) / back silicon-dioxide (SiO2) dielectric textures and were studied as function of two types of back reflectors: standard silver (Ag) and dielectric...

We have used 3-D optical modelling to investigate light management concepts based on periodic textures and material optimization for photovoltaic devices based on Cu(In,Ga)Se2 (CIGS) absorber material. At first, calibration of the software based on the characterization of a reference (1500-nm thick) CIGS device was carried out. The effects of 1...

High Voltage Direct Current (HVDC) transmission system technology has recently attracted a lot of attention within the power system community. Modular Multilevel Converter (MMC) HVDC is the state of the art HVDC transmission technology, which contains hundreds and even thousands of submodules. It is the modularity, scalability and efficiency...

The economic viability of on-road wireless charging of electric vehicles (EVs) strongly depends on the choice of the inductive power transfer (IPT) system configuration (static or dynamic charging), charging power level and the percentage of road coverage of dynamic charging. In this paper, a case study is carried out to determine the expected...

The addition of microsized fillers to polymers, in order to tailor their properties, has been extensively used in many industrial applications since the 1960s. The same approach applies to the field of electrical insulation. Epoxy resin is a widely used polymer in the electrical power sector, but it is usually loaded with microsized fillers,...

One of the important obstacles on the way to application of Si nanocrystals for development of practical devices is their typically low emissivity. In this study we explore the limits of external quantum yield of photoluminescence of solid-state dispersions of Si nanocrystals in SiO2. By making use of a low-temperature hydrogen passivation...

Magnetic cores like powdered iron cores have a variable permeability, which is dependent on the magnetic motive force of the inductor windings. When inductors are designed using such materials, the inductance varies as a function of the inductor current. This causes a non-linear current to flow through the inductor. In this paper, mathematical...
