  2. 11. Control and optimization of structures with fluid interaction

    Author : Dan Borglund; KTH; []
    Keywords : ;

    Abstract : Various problems on the optimal design of elastic structures subject to nonconservative fluid-dynamic forces are considered. The optimal design problem istypically posed as minimizing structural weight subject to constraints on structural stability. READ MORE

  4. 12. Synthesis of Controllers from a Range of Controller Architectures

    Author : Viktor Öwall; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : An algorithm specific digital signal processor is a powerful alternative to a general purpose signal processor for demanding specifications such as high throughput, low power, small size, etc. These properties are achieved as the processor architecture is tailored to the algorithm as opposed to the general purpose architecture which must suit a wide range of algorithms.

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

    Author : Karl Nilsson; Dan Henningson; Stefan Ivanell; Thorsten Lutz; KTH; []
    Keywords : ;

    Abstract : 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. READ MORE

  6. 14. Subsynchronous Resonance in Doubly-Fed Induction Generator Based Wind Farms

    Author : Selam Chernet; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Induction Generator Effect IGE ; Doubly-Fed Induction Generator DFIG ; SubSynchronous Resonance SSR ; passivity.; Wind power; impedance-based analysis; SubSynchronous Controller Interaction SSCI ;

    Abstract : The objective of this thesis is to investigate the risk for instabilities due to SubSynchronousResonances (SSR) conditions in large wind farms connected to series-compensated transmissionlines. In particular, the focus is on Doubly-Fed Induction Generator (DFIG) based windfarms. READ MORE
