  1. 1. Major Component Replacement on Floating Wind Turbines

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Kilian Galle; [2023]
    Keywords : ;

    Abstract : Among the challenges that floating offshore wind (FOW) energy faces today, operation and maintenanc ecosts, and especially major component replacements (MCR), are an important cost reduction lever. MCRs are defined as any failure on a wind turbine requiring the change of an entire main component of the turbine, such as a gearbox, generator, blade, nacelle, etc. READ MORE

  3. 2. Design and implementation of an energy harvesting system in a prosthetic limb

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Ódinn K. Rúnarsson; [2023]
    Keywords : Energy harvesting; Prosthetic limbs; Supercapacitors; Printed circuit boards; 3D printing; Energiinsamling; Lemmproteser; Superkondensatorer; Tryckta kretskort; 3D Utskrivning; Orkuöflun; Gervilimir; Ofurþéttar; Prentaðar rafrásir; Þrívíddarprentun;

    Abstract : Energy Harvesting, also known as power harvesting or ambient power, is the process of obtaining small amounts of power from secondary sources, such as vibrations, light, temperature variations and even radio-frequency emissions. These systems have been uncommon in personal and wearable electronics in the past, however they are slowly gaining traction. READ MORE

  4. 3. The influence of the built environment on the climate in different Swedish urban fabrics

    University essay from Högskolan Dalarna/Institutionen för information och teknik

    Author : Reem Mutwali; [2023]
    Keywords : Urban heat island; Urban morphology; The urban weather generator;

    Abstract : The urban heat island effect is usually disregarded when considering energy-efficient measures for the built environment. This study aims to present and analyze the effect of the urban built environment on the Swedish urban climate. This analysis is done in terms of assessing the mean urban heat island and monthly average air temperature. READ MORE

  5. 4. Relay settings for frequency derivative protection against islanding : Optimizing RoCoF-Hysteresis and Delay for the Swedish power grid: An investigation of relevant values

    University essay from KTH/Hälsoinformatik och logistik

    Author : Ahmad Safari; [2023]
    Keywords : Islanding; unintentional islanding; distributed energy resources; main grid; RoCoF; hysteresis; delay; Ödrift; oavsiktlig ödrift; distribuerade energiresurser; stamnät; RoCoF; hysteres; fördröjning;

    Abstract : This report addresses the parameter settings for a protective relay designed to safeguard a 15 kW wind turbine located in Rimbo, Norrtälje municipality, against unintentional islanding. This type of situation arises when distributed energy resources continue to supply local loads, even if the main grid has been unintentionally disconnected. READ MORE

  6. 5. Software Defined VNA : Measure Coupling Between Elements in an Antenna Array

    University essay from Uppsala universitet/Signaler och system

    Author : Alexander Söderlund; [2023]
    Keywords : VNA; Vector Network Analyser; SDR; KrakenSDR; S-parameter; Antenna Coupling;

    Abstract : With improvements in hardware of antenna receivers, fully digital arrays have been made possible to use in real time systems. These systems have a greater complexity, with the advantage of more dynamic system design since the use of the communication system can be changed with only a software change. READ MORE
