  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. Control Aid Implementation -Modelling and simulation of triple extruder-

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Karl Langsér; [2023]
    Nyckelord :Machine Learning; Extruder; Modelling; Simulation; Extreme learning machine; Chemical engineering; Technology and Engineering;

    Sammanfattning : In the production of their High Voltage Direct Current Cables (HVDC) and High Voltage Alternating Current Cables (HVAC), NKT uses triple extruders to create layers of insulation and semi-conduction. A model to predict the effect of extruder inputs on the cable’s insulation and semi-conducting layers has been created and trained to predict the extruder in discrete time. LÄS MER

  4. 3. Investigation of charge injection at electrode-dielectric interface relevant for HVDC cables : Simulation of charge injection and transport dynamics in electrical insulation for HVDC cables

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad mekanik

    Författare :Mohammed Mosa; [2023]
    Nyckelord :BCT model; charge injection; space charge density; electric field distribution; Fowler-Nordheim; Richardson-Schottky;

    Sammanfattning : A bipolar charge transport (BCT) model is used to simulate charge injection and transportdynamics inside insulation material which are used in a high voltage direct current (HVDC)cable. Gaining knowledge about space charge density and electric field distribution in theinsulation material enables minimising charge injection at the metal-insulator interface andavoiding unnecessary energy loss.

  5. 4. Power-sourced charging over PoE to enable high power peaks

    Master-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Deshane Devis; Babak Abedpour; [2023]
    Nyckelord :;

    Sammanfattning : In contrast with well-known traditional Closed Circuit Television cam-eras, nowadays most electronic devices including Internet Protocol surveil-lance cameras , Wireless Access Point, Network Routers, Voice over Internet Protocol technologies ,and so forth are all powered throughPower over Ethernet cables. These cables are capable of delivering bothDirect Current power and data simultaneously using a single main cable for the Local area network, this tremendously assisted system integra-tors and network installers to deploy electronic devices in locations that lack electrical circuitry and eventually eliminating the extra expensesof installing additional electrical wiring as well as power supplies.
