  1. 1. Harmonic Filters For Electronic Drive Systems Targeting Aircraft Applications

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Emelie Berglund; [2023]
    Keywords : Active Cancellation Filter; BLDC;

    Abstract : Climate change pressures fossil-driven vehicles into electrification to sustain a healthy planet and environment for its inhabitants. Air traffic contributes to the ongoing climate crisis, and electric aircraft is taking its toll on the avionics market. READ MORE

  3. 2. Damping of sub-synchronous control interactions with a STATCOM : Wind farms & series compensated power lines

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Leonardo Alvarez Urrutia; [2022]
    Keywords : Sub-Synchronous Control Interactions; Power Systems; STATCOM; Network Stability; Doubly-Fed Induction Generator; Impedance-Based Stability Analysis;

    Abstract : The power converter is one of the key components in power system applications such as high voltage direct current (HVDC) systems and the grid connection of intermittent sources such as wind and solar power. However, the increased penetration of converter-based generation introduces challenges, such as sub-synchronous interaction between the converter control system and the grid. READ MORE

  4. 3. Role of damping in NVH CAE procedures

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Rahul Sharma; [2021]
    Keywords : NVH; CAE; Damping;

    Abstract :   Automotive manufacturers currently face a challenge with expeditious enhancement of the vibro-acoustic properties of their vehicles. A major reason for this setback is the limited design information available during initial development stages added with limited knowledge of damping within complex structures. READ MORE

  5. 4. Active Control of High­-Speed Flexible Rotors on Controllable Tilting­-Pad Journal Bearings : Theory and Experiment

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Paul-Henrik Bull; [2021]
    Keywords : ATPJB; Fluid-Film Lubrication; Model based control; Vibration Control;

    Abstract : A common choice of bearing for industrial applications such as turbomachinery and rotating compressors is the Tilting-Pad Journal Bearing (TPJB) due to its excellent stability properties. TPJB's are however limited by the reduction of damping in the fluid film at high velocities. READ MORE

  6. 5. Experimental Investigation of Fluid-added Parameters on a Kaplan Runner

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Malin Strandberg; [2021]
    Keywords : Added mass; added inertia; fluid dynamics; hydropower; Kaplan turbine; fluid-solid interaction;

    Abstract : In order to reach climate and environmental goals, Sweden is increasing the implementation of intermittent renewable energy sources such as wind and solar power to the electricity grid. The increase of intermittent energy sources is rising power regulation requirement towards hydropower, which increasingly exposes the hydraulic turbines to high loads and fluctuating hydraulic forces.
