   Sammanfattning : Synchronous generators have been used in hydropower from more than a century where, traditionally, the field current is transferred to the rotor using slip rings and carbon brushes. There are some major disadvantages following the use static excitation; regular and expensive maintenance, as well as a source of carbon dust which, due to buildup, may cause short circuits. LÄS MER

3. 2. Technical Feasibility Study of an IGBT-based Excitation System

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

   Författare :Johan Frisk; [2017]
   Nyckelord :Cabinet design; inverter cabinet; IGBT; excitation system; EMC; electrical connection; Skåpdesign; IGBT; magnetiseringssystem; EMC; elektrisk anslutning;

   Sammanfattning : This thesis aims to design a cabinet to house some of the required hardware to realize a 1000 A IGBT inverter controlled static excitation system. In the thesis practical design considerations are identified and solved. The suggested excitation system requires a cabinet to house the inverters. LÄS MER
