1. Methods for including stiffness parameters from reduced finite element models in simulations of multibody systems
University essay from Uppsala universitet/Fasta tillståndets elektronikAbstract : Two methods using lumped element (lumped parameter) methods to model flexible bodies have been presented. The methods are based on the concept of using a Guyan reduced stiffness matrix to describe the elasticity of a body. READ MORE

2. Simulations of vertical axis wind turbines with PMSG and diode rectification to a mutual DC-bus
University essay from Uppsala universitet/Institutionen för teknikvetenskaperAbstract : 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.
