  1. 1. 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

  3. 2. Streamlining 3D City Modeling for Urban Flow Simulations by Automatic Integration of Multisource Topography

    University essay from Umeå universitet/Institutionen för fysik

    Author : Klara Lindroth; [2023]
    Keywords : automatic 3D city models; surface reconstruction; geometry pre-processing; CFD; OSM height attributes;

    Abstract : In the workflow of computational fluid dynamics, geometry preparation is commonly the most time-consuming step. For a fast CFD simulation, automatic surface reconstruction to obtain 3D city models for a chosen area is essential. To address this need, a literature study was conducted to map available data suitable for 3D city models. READ MORE

  4. 3. Causes of and solutions to reduce excess material in production processes : A study of electrical motors and generators at ABB Machines

    University essay from Linköpings universitet/Industriell miljöteknik

    Author : Wilma Fager; Hanna Engberg; [2023]
    Keywords : Excess material; investigation; production processes; reduce; material usage; minimize; components;

    Abstract : This thesis focus on the investigation of material usage in the production processes of electrical motors and generators at ABB Machines, a company based in Västerås, Sweden. The study aims to understand the reasons for the occurrence of excess material after the assembly of a motor or generator and explore possible solutions to minimize its occurrence. READ MORE

  5. 4. Paletto: An Interactive Colour Palette Generator : Facilitating Designers’ Colour Selection Processes

    University essay from Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Author : Rema Salman; [2022]
    Keywords : Colour-palettes design; Colour extraction; Machine-learning; K-means algorithm; Human-computer interaction; Human-automation collaboration; User experience; User engagement.;

    Abstract : Digital growth and the adaption of internet-based solutions, particularly artificial intelligence and machine learning, have dramatically changed the way design is done today. This rapid change in technology has challenged the level of automation, which influences the human-automation interactions with the available colour-design tools (academic and commercial). READ MORE

  6. 5. "Resonance frequency, Q-factor, coupling of a cylindrical cavity and the effect on graphite from an alternating electric field".

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Jakob Gölén; Simon Persson; [2021]
    Keywords : Q-factor; Resonance frequency; Cavity; Microwaves; Heating; Q-faktor; Resonansfrekvens; Kavitet; Mikrovågor; Uppvärmning;

    Abstract : The purpose of this project was to investigate a cylindrical cavity resonator and use microwaves to heat up a material in the cavity. This was done by measuring the Q-factor and the resonance frequency of the cavity, both with and without material inside. READ MORE
