  1. 16. Wind turbine dynamic - application to foundations

    University essay from KTH/Bro- och stålbyggnad

    Author : Cyril Bailly; [2014]
    Keywords : Wind turbine dynamic; Foundation; Finite element analysis;

    Abstract : These latest years, the green energy is highlighted and new technologies appeared. It is the case for wind turbines. The aim of latest developments has been to increase the power output. The use of new material enables the design of wind turbine with an impressive height, more and more flexible, inducing significant dynamic forces. READ MORE

  3. 17. Improving Low Voltage Ride-Through Requirements (LVRT) Based on Hybrid PMU, Conventional Measurements in Wind Power Systems

    University essay from Avdelningen för fysik och elektroteknik

    Author : Chinedum Ekechukwu; [2014]
    Keywords : State Estimation; Power Systems; Unscented Kalman Filters; Phasor Measurement Units;

    Abstract : Previously, conventional state estimation techniques have been used for state estimation in power systems. These conventional methods are based on steady state models. As a result of this, power system dynamics during disturbances or transient conditions are not adequately captured. READ MORE

  4. 18. Effects of Asymmetry and Other Non-Standard Excitations on Structural Dynamic Forced Response Analysis of Turbomachinery Flow-Path Components

    University essay from KTH/Kraft- och värmeteknologi

    Author : Anton Gagne; [2014]
    Keywords : ;

    Abstract : A recent paper explored a potential deficiency in the single frequency harmonic response structural dynamic analysis approach typically used to assess a resonant condition in turbomachinery flow path components. This deficiency is prevalent in supersonic flow conditions when non-adjacent stages are present. READ MORE

  5. 19. Simulation of a Self-bearing Cone-shaped Lorentz-type Electrical Machine

    University essay from Elektricitetslära

    Author : Jim Ögren; [2013]
    Keywords : Self-bearing machine; bearingless machine; cone-shaped flywheel; 6 degrees of freedom control;

    Abstract : Self-bearing machines for kinetic energy storage have the advantage of integrating the magnetic bearing in the stator/rotor configuration, which reduces the number of mechanical components needed compared with using separated active magnetic bearings. This master's thesis focus on building a MATLAB/Simulink simulation model for a self-bearing cone-shaped Lorenz-type electrical machine. READ MORE

  6. 20. Design of a High Altitude Wind Power Generation System

    University essay from Maskinkonstruktion

    Author : Imran Aziz; [2013]
    Keywords : High altitude wind power; Renewable energy; Kite; Driveline; Design; CAD; Simulation;

    Abstract : One of the key points to reduce the world dependence on fossil fuels and the emissions of greenhouse gases is the use of renewable energy sources. Recent studies showed that wind energy is a significant source of renewable energy which is capable to meet the global energy demands. READ MORE
