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

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

    Author : Longgang Su; [2022]
    Keywords : 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.;

    Abstract : 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. READ MORE

  3. 2. Analysis of Different Switching Patterns to Minimize Losses in a Six- Phase Drive for Marine Application

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

    Author : Yanick Patrick Frei; [2021]
    Keywords : Multiphase machines; Switching patterns; Winding conduction losses; Converter losses; MATLAB SIMULINK; Flerfasmaskiner; Modulatorer; Spolledningsförluster; Omvandlarförluster; MATLAB SIMULINK;

    Abstract : Multiphase machines have gained a lot of popularity during the recent years, as they offer certain benefits over their three- phase counterparts. This work investigates the losses of a six- phase drive system for a marine application when supplied by four different switching patterns (also referred to as modulators). READ MORE

  4. 3. Integrating Wind Power into The Electric Grid : Predictive Current Control Implementation

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

    Author : Ahmad Badran; [2020]
    Keywords : Model predictive control; Wind turbine; Predictive current control; Inverter; Simulink; Active power; Reactive power.;

    Abstract : The increasing penetration of wind power into the power system dominated by variable-speed wind turbines among the installed wind turbines will require further development of control methods. Power electronic converters are widely used to improve power quality in conjunction with the integration of variable speed wind turbines into the grid. READ MORE

  5. 4. Analysis of harmonic cross-modulation in HVDC line-commutated converters for practical design purposes

    University essay from Högskolan Väst/Avdelningen för Industriell ekonomi, Elektro- och Maskinteknik

    Author : Casper Karlsson; [2018]
    Keywords : Power transmission; design; filters;

    Abstract : The use of HVDC has many benefits over HVAC for some specific power transmission purposes. However, two major problems with HVDC links are that the converters produce harmonics and consume reactive power. Electrical filters are used to compensate for this and are a major cost driver of HVDC links. READ MORE

  6. 5. Automatically measuring the losses of a transformer

    University essay from Blekinge Tekniska Högskola/Institutionen för signalbehandling

    Author : Murad Junaydin Mohamed; [2016]
    Keywords : ;

    Abstract : This thesis is an ongoing project of Alstom Power Sweden AB, Växjö with a collaboration of Blekinge Institute of Technology [BTH] to automatically measure the losses of a transformer. So far the company performed the measurements manually to get this loss, and they decided to automatize the measurement process. READ MORE
