  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. Design and performance comparison of Two-level and Multilevel Converters for HVDC Applications

    University essay from

    Author : Carlos Castillo Bonilla; Sweta Merilyn Tigga; [2019-07-03T12:44:07Z 2019-07-03T12:44:07Z 2011]
    Keywords : Elkraftteknik; Electric power engineering;

    Abstract : The purpose of this thesis is to compare a two-level and a multilevel converter for HVDC substation. For this study, both topologies were designed with different modulation strategies and compared on the basis of size, power losses and impact on power quality. READ MORE

  4. 3. Detection and location of HVDC commutation faults from PMU data

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Alejandro Belinchon Calderon; [2018]
    Keywords : HVDC-links; HVDC converters; Commutation failures; Phasor measurement units PMUs ; Electric power systems; Wide Area Measurement systems WAMS ; Standard IEEEC 37.118; Single-line to ground faults; Three-Phase faults; Fault detection and location; Nordic 32; DigSilent-PowerFactory; PSCAD; MATLAB-Simulink; Symmetrical components.; Technology and Engineering;

    Abstract : Commutation Failures in LCC HVDC converters is a topic that is normally addressed from the component perspective, looking at converters’ internal signals. How these commutation failures affect the outer AC network is not deeply understood yet. READ MORE

  5. 4. Power Loss Evaluation of Submarine Cables in 500 MW Offshore Wind Farm

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Lahiru Kushan Jayasinghe; [2017]
    Keywords : Power Loss; Offshore Windfarm; Submarine Cables; HVAC; HVDC LCC; HVDC VSC; MATLAB Simulink;

    Abstract : The main objective of this thesis is to develop a new methodology to evaluate the transmission cable losses of wind-generated electricity. The research included the power loss variations of submarine cables in relation to the line length, cable capacity and the transmission technology in an offshore wind farm having a capacity of 500 MW.

  6. 5. High Level Synthesis of FPGA-Based Digital Filters

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Gerald Baguma; [2014]
    Keywords : ;

    Abstract : This thesis work is aimed at the high level synthesis of FPGA based IIR digital filters using Vivado HLS produced by Xilinx and HDL coder produced by MathWorks. The Higher Layer Model of the filter was designed in Vivado HLS, MATLAB and Simulink. Simulations, verification and Synthesis of the RTL code was done for both tools. READ MORE
