1. 1. Kilowatt Three-phase Rotary Transformer Design for Permanent Magnet DC Motor with On-rotor Drive System

   Master-uppsats, Mittuniversitetet/Avdelningen för elektronikkonstruktion

   Författare :Ye Xu; [2016]
   Nyckelord :contactless energy transfer; transformer power loss; iron loss; iron loss model; rotary transformer; three-phase transformer; finite element method; COMSOL Multiphysics; electrical steel; electrical steel manufacturing process;

   Sammanfattning : The aim of this thesis is to design a kilowatt three-phase step-down rotary transformer for a permanent magnet DC motor. The permanent magnet DC motor has an on-rotor drive system, and therefore requiring a power supply that can transfer power to its drive unit without mechanical contact. LÄS MER

3. 2. Load flow control and optimization of Banverket’s 132 kV 16 2/3 Hz high voltage grid

   Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

   Författare :Annica Lindén; Anna Ågren; [2005]
   Nyckelord :132 kV; rotary converter; load flow; power flow; feeding line; catenary; tap changer; control system; railway; electrification;

   Sammanfattning : The purpose of this thesis was to investigate the possibility of power flow control, on a section of a railway grid fed by rotary converters, using an extra feeding line. Two possible solutions for the power flow control were examined. LÄS MER
