    Författare :Nicklas Johansson; Hans-Peter Nee; Göran Andersson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adaptive Control; Controlled Series Compensator; Dynamic Power Flow Controller; Frequency Scanning; Phase-Shifting Transformer; Power Controller Plane; Power Flow Control; Power Oscillation Damping; Subsynchronous Resonance; Thyristor Controlled Series Compensator; Thyristor Switched Series Compensator; Transient Stability; Electrical engineering; Elektroteknik;

    Sammanfattning : This thesis studies different aspects of Flexible AC Transmission System (FACTS) devices which are used to improve the power transfer capability and increase the controllability in electric power systems. In the thesis, different aspects on the usage and control of Dynamic Power Flow Controllers (DPFC) and related FACTS devices are studied. LÄS MER

  3. 2. Power System Damping - Structural Aspects of Controlling Active Power

    Författare :Olof Samuelsson; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics and Electrical technology; controller interaction; mode controllability; mode observability; mechanical equivalent; linear differential-algebraic equations; modal analysis; active power; power system damping; electro-mechanical oscillations; Elektronik och elektroteknik; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : Environmental and economical aspects make it difficult to build new power lines and to reinforce existing ones. The continued growth in demand for electric power must therefore to a great extent be met by increased loading of available lines. LÄS MER

  4. 3. The Robustness and Energy Evaluation of a Linear Quadratic Regulator for a Rehabilitation Hip Exoskeleton

    Författare :Rabé Andersson; Niclas Björsell; Daniel Rönnow; Gianni Borghesan; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hip Rehabilitation Exoskeleton; Robust Controller; Energy Consumption; Series Elastic Actuator SEA ; LQR Control; Luenberger State Observer; Torque Control; Höftexoskelett för rehabilitering; Robust reglering; Energiförbrukning; serieelastiskt manöverdon SEA ; LQR reglering; Luenberger State Obser-ver; Moment reglering;

    Sammanfattning : The implications of gait disorder, muscle weakness, and spinal cord injuries for work and age-related mobility degradation have increased the need for rehabilitation exoskeletons. Specifically, the hip rehabilitation exoskeletons due to a high percentage of the mechanical power is generated by this join during the gait cycle. LÄS MER

  5. 4. SDN-Enabled Resiliency in Computer Networks

    Författare :Jonathan Vestin; Andreas Kassler; Yan Zhang; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; networking; sdn; openflow; resiliency; icn; mmwave; 5g; wlan; Computer Science; Datavetenskap;

    Sammanfattning : In computer networking, failures, such as breaking equipment, cable cuts, power failures and human errors continuously cause communication interruptions. Such failures may result in dissatisfied customers, loss of product reputation, violation of SLAs and even critical failures in industrial systems. LÄS MER

  7. 5. Numerical computations of wind turbine wakes and wake interaction

    Författare :Karl Nilsson; Dan Henningson; Stefan Ivanell; Thorsten Lutz; KTH; []
    Nyckelord :;

    Sammanfattning : When wind turbines are placed in farms, wake effects reduce the overall power production. Also, turbine loads are significantly increased since turbulence levels are high within the wake flow. LÄS MER
