  3. 3. Power System Oscillations - Detection, Estimation and Control

    University dissertation from Department of Industrial Electrical Engineering and Automation, Lund Institute of Technology

    Author : Morten Hemmingsson; Lund University.; Lunds universitet.; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik; oscillation; power system; damping; power swing; distance protection; detection; estimation; real-time; reactive co-variation; control; Electrical engineering; load modulation; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Abstract : The topic of this thesis is the electro-mechanical oscillations which to some extent always are present in a power system. The demand of electric power is ever increasing. At the same time, the tolerance of disruptions in the power supply is decreasing. READ MORE

  4. 4. On the Load Distribution and Design of a Chain Drive

    University dissertation from Machine Elements Division, P.O.Box 118,SE- 22100 Lund,Sweden

    Author : Ingvar Troedsson; Lund University.; Lunds universitet.; [1999]

    Abstract : Three methods are presented to calculate the load distribution in a chain drive containing two sprockets and one chain. The rollers, which are in contact with the sprockets, can move along the tooth flanks and their positions are given by force equilibrium. READ MORE

  5. 5. Laser-Driven Particle Acceleration - Improving Performance Through Smart Target Design

    University dissertation from Camilla Nilsson, Department of Physics, Division of Atomic Physics, Lund University

    Author : Matthias Burza; Lund University.; Lunds universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; wakefield; ultra-relativistic; ultra-intense; TNSA; Terawatt; sheath; proton; polarimetry; plasma mirror; plasma; Petawatt; particle; oscillation; Normarski; micromachining; LWFA; laser; interferometry; electron; contrast; acceleration; bubble; Fysicumarkivet A:2012:Burza;

    Abstract : Laser-driven particle acceleration makes use of sub-picosecond, pulsed, high-power laser systems, capable of producing intensities ~10^{19} W/cm^2 at the laser focus to form plasmas, and use ultra-relativistic and nonlinear dynamics to produce quasistatic acceleration fields. This allows electrons to be accelerated to ~100 MeV over sub-centimetre distances, while protons may be accelerated to the ~10 MeV regime. READ MORE
