  1. 1. Investigation of inductive electric fields in Earth’s magnetotail using Magnetospheric Multiscale (MMS) multipoint measurements

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

    Author : Marco Guerra; [2022]
    Keywords : ;

    Abstract : The mutual interaction between the solar wind and the geomagnetic field generates the magnetosphere. The magnetosphere is characterized by many large-scale perturbations, such as substorms, which are responsible for variations in the magnetic field. READ MORE

  3. 2. Simulation of Transformer Inrush Currents and Their Impact on the Grid

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Juan de la Peña Toledo; [2022]
    Keywords : Transformer; Energization; PSS E; PSCAD; Simulation; Magnetizing current; Inrush current; Technology and Engineering;

    Abstract : This MSc Thesis’s main objective is to determine the impact of transformer inrush currents in the grid and develop a tool that helps E.ON Energidistribution AB evaluate transformer sizing. The motivation of E. READ MORE

  4. 3. Soft Energization and Blackout Recovery of Offshore Wind Farm Export System

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

    Author : Nicolas Mile; [2022]

    Abstract : Power generation of the future will be dominated by renewable energy sources. This is a positive trend as society aims to improve sustainability, energy security, and reduce CO2 emissions. This progress however bears challenges for the power systems of the future. READ MORE

  5. 4. Resonant overvoltages caused by transformer energization and saturation : Two EMT case studies conducted using models of the grid in Stockholm and an off-shore wind farm

    University essay from Uppsala universitet/Elektricitetslära

    Author : Gustav Sundberg; [2021]
    Keywords : Resonant overvoltages; Resonance frequency; Parallel resonance; EMT studies; Transformer saturation; Off-shore wind power; Inrush current; Sympathetic Inrush; Resonanta överspänningar; Resonansfrekvens; Parallellresonans; EMT-studier; Magnetiseringsström; Havsbaserad vindkraft;

    Abstract : This thesis investigates the impact of resonant overvoltages and their origin. Series and parallel resonances are present in any electrical grid. The frequency of which this resonance occurs is called resonance frequency. READ MORE

  6. 5. Eliminating zero-missing phenomenon in long, high voltage, underground cables

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

    Author : Agnes Linnet; [2019]
    Keywords : Underground cable; zero-missing phenomenon; switching transients; shunt reactors; underexcited generators; Underjordisk kabel; nollbristande fenomen; växlingstransienter; shuntreaktorer; underexiterad generatorer;

    Abstract : The maximum length of an high voltage underground cable (HV UGC) cable is oftenconstrained by the criterion that the cable cannot have more than 50% reactivepower compensation. If this limit is exceeded the current in the circuit breaker maynot have a zero crossing after energization, which is referred to as the zero missingphenomenon. READ MORE
