  1. 1. Development and Analysis of Small Signal DQ-Frame Model for Low Frequency Stability of Train Converters

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

    Author : Fabian Tidner; [2023]
    Keywords : Low Frequency stability; DQ-frame modeling; Single phase converter; Electric rail way systems; Lågfrekvent stabilitet; DQ-ram modellering; Enfasig likriktare; Elektriska järnvägssystem;

    Abstract : In order to meet the increasing demand for sustainable transportation, trains need to run with tighter schedules, more departures and more trains in depot. Multiple trains in depot has been linked to low frequency instability at many locations around the world. READ MORE

  3. 2. Alternative traction system for road-rail vehicles

    University essay from Lunds universitet/Innovation

    Author : Jakob Runevad; [2023]
    Keywords : Product development; electric traction; construction equipment; road-rail vehicles.; Technology and Engineering;

    Abstract : Excavators have traditionally been diesel driven with hydraulic actuators, but with the ongoing electrification of vehicles, smaller electric excavators are getting more common. Larger electrical excavators are still in a prototyping or early production stage but can be expected to grow. READ MORE

  4. 3. Paratransit and Bus Rapid Transit Interaction Approaches and Corresponding Barriers

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Messner Laura; [2020]
    Keywords : informal public transport; multi-regimes; socio-technical transition theory; stakeholder theory; Sub- Saharan Africa; sustainable development;

    Abstract : Public transport in many Sub-Saharan African cities consists of paratransit, mini-to-medium-sized buses, which provide public transport and operate demand-driven and unscheduled. This form of public transport is often seen as less safe, less dependable, and environmentally unfriendly. READ MORE

  5. 4. Pressurizing of high-pressure fuel system forsingle cylinder test cell

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Gustaf Glaad; [2019]
    Keywords : Alternative fuels; Ultra high-pressure fuel system; Common rail direct injection fuel system; Diesel-like fuels; Compression ignited fuels;

    Abstract : This master thesis covers the development of a high-pressure fuel system for compression ignitedfuels such as diesel and diesel-like fuels that will be deployed into a single cylinder test cell at AVLMTC Södertälje, Sweden. The test cell is used by AVL to conduct research and testing of new fuelsfor their customers and this new fuel system will widen the span of fuels able to be tested by theequipment. READ MORE

  6. 5. Modelling of high-pressure fuel system for controller development

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Eric Pettersson; [2019]
    Keywords : Common-Rail Direct Injection; fuel system; water hammer; pressure oscillations; physical modelling; state-space representation;

    Abstract : This master thesis treats the modelling of a common-rail direct fuel injection system where pressure generation is decoupled from the injection process. It has been shown that the fuel pressure plays a vital role for the general performance of the engine, affecting both emissions and efficiency, and it is carefully regulated to achieve optimal performance at different operating points.
