  1. 1. Simulations of vertical axis wind turbines with PMSG and diode rectification to a mutual DC-bus

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Fjellstedt Christoffer; [2017]
    Keywords : vertical axis wind turbines; VAWT; mutual DC-bus; mutual topology; simulations; diode rectification;

    Abstract : Transient simulations were performed with MATLAB Simulink on a mutual wind park topology, where three vertical axis wind turbines equipped with permanent magnet synchronous generators were connected to a mutual DC-bus through passive diode rectification. The aim with the work was to show the effects of two different kinds of loads on the system in respect to generator torque, rotor speed, produced power by the generators and the power on the DC-bus.

  3. 3. Model calibration of a vertical wind power plant using Dymola/Modelica

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Stefan Andersson; Jonatan Strömner; [2013]
    Keywords : Technology and Engineering;

    Abstract : Wind energy has been used by mankind since ancient times and the last decades have seen large technological advancements in the field of wind turbines. One technology, although not very common, for harnessing the energy in the wind is the vertical axis wind turbine (VAWT). READ MORE

  4. 4. Modification of Aeroelastic Model for Vertical Axes Wind Turbines

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Damoon Rastegar; [2013]
    Keywords : vertical axis wind turbine VAWT ; finite element method FEM ; Timoshenko beam theory; structural damping; modal measurement.;

    Abstract : In wind turbines, flow pressure variations on the air-structure interface cause aerodynamic forces. Consequently the structure deforms and starts to move. The interaction between aerodynamic forces and structural deformations mainly concerns aeroelasticity. READ MORE
