  1. 1. Centralised MPC for Long-term Voltage Stability Control of Power System

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

    Author : Johan Hallberg; [2023]
    Keywords : Voltage stability; Model predictive control; Tap-changing transformer; Capacitor bank; Spänningsstabilitet; Model prediktiv reglering; Lindningskopplare; Kondensatorbank;

    Abstract : In a power system it is important to keep voltages at specific levels at network buses. Deviations from that can lead to reduced efficiency of transferred power or, in more severe cases, widespread power outages affecting large parts of society. There exists a variety of power system devices that have the ability to regulate the voltage levels. READ MORE

  3. 2. Characterizing coil windings noise due to compressive fault currents : A study to determine if there is a characteristic noise from transformer windings due to fault currents

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

    Author : Simon Lundgren; [2022]
    Keywords : Transformer windings; short circuit forces; current pulses; microphone; Comsol Multiphysics; FFT; Transformator lindningar; strömpulser; mikrofon; kortslutingskrafter; Comsol Multiphysics; FFT;

    Abstract : Transformers are essential for modern power distribution system. They are efficient and enable the voltages to be transformed up for transportation of electricity and back down for consumer use. The reliability of the transformer is affected by faults and fatigue of the copper. READ MORE

  4. 3. Pre-study of optical LED units for shunting signals

    University essay from KTH/Hälsoinformatik och logistik

    Author : Tobias Adolfsson; Axel Dellenby; [2021]
    Keywords : LED - Light Emitting Diode; Booster Converter; MLCC - Multi-layer capacitor; ESR - Equivalent Serie Resistance; OU - Optical Unit; Reactive compensation; LED - lysdiod; step-up omvandlare; MLCC - flerskiktskeramisk kondensator; ESR - ekvivalent serie motstånd; OU - optiskt enhet; reaktiv kompensering;

    Abstract : Alstom wanted to investigate the possibility of adapting its light emitting diode (LED) technology for shunting signals in train traffic. The LED technology uses 50V, but Alstom wants to adapt it for 12V. The LED technology is energy efficient but needs to be adapted for existing signal interlocking by drawing a higher current.

  5. 4. High Magnetic Field in Low Temperature Vacuum Conditions : Magnet Design, Modeling and Testing

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Nehir Schmid; [2020]
    Keywords : magnet; pulsed magnet; X-ray diffraction; crystallography; zylon; magnet design; magnetic field; high magnetic field; strong magnetic field; split-coil magnet;

    Abstract : The Swiss Free Electron Laser (SwissFEL) at the Paul Scherrer Institute is a national prestige project that will enable ground breaking new x-ray scattering experiments in areas such as biology, chemistry and physics. A plannedactivity is to generate possibility for x-ray diffraction under high pulsed magnetic fields to explore quantum mattermaterials. READ MORE

  6. 5. Developing Verification Models for Corona Discharge Suppression in High Voltage Capacitor Banks

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Mohammadjavad Javadi; [2020]
    Keywords : Corona discharge; Suppression ring; High voltage capacitor banks;

    Abstract : Due to the universal considerable population and economic growth rate, demands for energy have risen significantly over the past decade. This means that the integration of renewable energies in the power grid has escalated as well as requests for reactive power compensation, voltage stability, and mitigation of harmonic filters.
