  1. 1. A Digital Test Bench for Pneumatic Brakes

    University essay from KTH/Spårfordon

    Author : Bastian Schick; [2021]
    Keywords : Compressed air brake; Freight train; Modular simulation; Pneumatics; Railways; System modelling; Tryckluftsbroms; Godståg; Modulär Simulering; Pneumatik; Järnväg; Systemmodellering;

    Abstract : This master’s thesis covers the structuring and implementation of a digital testbench for the air brake system of freight trains. The test bench will serveto further improve the existing brake models at Transrail Sweden AB. Theseare used for the optimised calculation of train speed profiles by the DriverAdvisory System CATO.

  2. 2. Study of an Isolated and a Non-Isolated Modular DC/DC Converter : In Multi-Terminal HVDC/MVDC grid systems

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

    Author : Ranjithh Raj Ram Prakash; [2019]
    Keywords : High power high voltage DC-DC converter; Isolated non-isolated DC-DC converter; HVDC MVDC interconnection; HVDC HVDC point-to-point link; Modular multilevel converter; Transformer driven MMC; Steady state transient DC fault analysis; High Power DC DC-omvandlare med hög spänning; Isolerad och icke-isolerad DC-DC-omvandlare; HVDC MVDC-anslutning; HVDC HVDC-punkt-till-punkt-länk; Modulär multilevelomvandlare; Transformatorstyrd MMC; Stabilitet DC felanalys;

    Abstract : För sammankoppling av multi-terminala HVDC-system med punkt-till-punkt kopplingar ärDC-DC-omvandlaren den enda möjliga sammankopplingen. Därför genomgår problemenmed spänningsmatchning och likspänningsströmbegränsning i högspännings DC-systemomfattande forskning samt ligger i fokus för denna avhandling. READ MORE

  3. 3. A New Cell Bypass Arrangement and Control for Modular Multilevel Converters based on Thyristor Forced Commutation Circuit

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Soteris Poyiadjis; [2017]
    Keywords : ;

    Abstract : HVDC transmission lines are a competitive and in some cases are proven to bea superior choice compared to AC transmission applications. Suitable convertershave been developed for that matter where Modulär Multilevel Converters (MMC)are highly preferred due to their low losses, no filtering requirementsand direct andfast control of AC and DC side.

  4. 4. Modularity of a heater simulator and implementation in a prototype HIL-system

    University essay from KTH/Maskinkonstruktion (Inst.); KTH/Maskinkonstruktion (Inst.)

    Author : Christoffer Lindahl; Mattias Nilsson; [2017]
    Keywords : ;

    Abstract : The thesis is about a modular low budget prototype hardware-in-the-loop system for testing diesel heaters. A modular plant model of the heater has been developed using model-based development in Simulink. The model has been derived mathematically from tests and empirical investigations. READ MORE
