  1. 1. Local voltage control in a low voltage grid with high photovoltaic penetration

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Joakim Bakklund; [2024]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This thesis examines how active power control (Volt-Watt control) and reactive power compensation (Volt-VAr control) can help limit voltage increases on the low voltage grid due to high photovoltaic (PV), installations. Due to the large increase in interest to install small scale PV-systems within residential areas the Distribution System Operator E. LÄS MER

  3. 2. Closed-loop control and data- recording of a modular-multilevel converter (MMC)

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Longgang Su; [2022]
    Nyckelord :Modular multilevel converters MMCs ; filed programmable gate array FPGA ; direct memory access DMA ; energy closed-loop control; data recording; ethernet.; Modulära multilevel-omvandlare MMC ; filed programmeable gate array FPGA ; direkt minnesåtkomst DMA ; energistyrning med sluten slinga; datainspelning; ethernet.;

    Sammanfattning : Modular multilevel converters (MMCs) are the preferred converter solution in flexible ac transmission systems (FACTS) and high-voltage direct current (HVDC) applications. This is due to the high quality of the voltage and current signals, lower overall losses, and fewer problems with switching-related EMI. LÄS MER

  4. 3. Excitation system – simulation, tuning and evaluation

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Philip von Heideken; [2021]
    Nyckelord :;

    Sammanfattning : Swedish Electrical and Power Control AB (Svea Power) offers excitation systems for electrical production plants. An excitation system controls the electrical performance of the generator’s three phase outputs and must meet requirements set out in the business agency “Svenska Kraftnäts (SvK:s) föreskrifter, SvKFS 2005:2”.

  5. 4. Modular Battery Management System interface to integrated Vehicle Control Unit : Creating a BMS playground using Arduino

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Joel André; [2020]
    Nyckelord :;

    Sammanfattning : Development today has moved more towards battery technology, partly due to the increased demand of electric vehicles (EVs). The quest for a sustainable society is at an all-time high, with electrification of almost all devices only being the beginning. LÄS MER

  7. 5. Implementation of an Automatic Voltage Regulator for Synchronous Machines on an FPGA

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :Eric Fjärstedt; [2019]
    Nyckelord :hydro power; synchronous machine; magnetisation; LabVIEW; FPGA;

    Sammanfattning : Synchronous generators used for hydro power and nuclear power is a well known topology but there is a vast amount of intricate technologies and methods to making them function properly. This masters thesis covers the development, implementation and verification of a magnetisation system for a synchronous generator. LÄS MER
