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

   Uppsats för yrkesexamina på avancerad nivå, Elektricitetslära

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

   Sammanfattning : 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. LÄS MER

3. 2. PLL design for inverter grid connection : Simulations for ideal and non-ideal grid conditions

   Kandidat-uppsats, Teknisk-naturvetenskapliga vetenskapsområdet

   Författare :Jim Ögren; [2010]
   Nyckelord :PLL; inverter; Phase locked loop; symmetrical optimum method;

   Sammanfattning : In this report a phase locked loop (PLL) system for grid voltage phase tracking has been investigated. The grid voltage phase angle contains critical information for connecting a power plant, such as a wave energy converter, to the grid. LÄS MER
