   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Pengpeng Sun; [2022]
   Nyckelord :Sparse Neutral Point Clamped Converter; Industrial Variable Speed Drives; Silicon IGBT; Calorimetric Measurement; Reverse Recovery Energy; Sparse Neutral Point Clamped Converter; Industriella Varvtalsstyrda Motordrifter; Silicon IGBT; Kalorimetrisk Mätning; Energi för Återhämtningsprocess;

   Sammanfattning : This thesis project focuses on the simulation, design, hardware realization, and performance evaluation of a Three-phase Three-level (3-L) Sparse Neutral Point Clamped Converter (SNPCC) for Industrial Variable Speed Drives (VSDs). The basic operating principle of the SNPCC is briefly described based on switching functions. LÄS MER

   Magister-uppsats, Karlstads universitet/Avdelningen för fysik och elektroteknik

   Författare :Agha Rehmat Ali; [2018]
   Nyckelord :Predicted Speed;

   Sammanfattning : In order to achieve energy savings for belt conveyor system, speed control provides one of the best solutions. Most of the traditional belt conveyors used in the industries are based on constant speed for all operational times. LÄS MER

4. 3. Elkvalitéproblem vid varvtalsstyrd motordrift i industrimiljö

   M1-uppsats, KTH/Data- och elektroteknik

   Författare :Rick Gerkens; David Berg; [2013]
   Nyckelord :Harmonics; variable speed motor operations; frequency inverter control; power quality; power quality problems; harmonics modulation; Ramboll; Sandvik Mining; övertoner; varvtalsstyrd motordrift; frekvensstyrning; elkvalitè; elkvalitèproblem; modellering av övertoner; Ramböll; Sandvik Mining;

   Sammanfattning : Övertoner orsakade av varvtalsstyrda motordrifter ger problem i industrisystem. Syftet med studien är att identifiera problemen och ge rekommendationer för att undvika dem. Studien utfördes som examensjobb på KTH för konsultföretaget Ramböll. En litteraturstudie i ämnet kombinerades med elkvalitémätningar på drifter hos Sandvik Mining. LÄS MER

5. 4. Evaluation of Economical Impact of Energy Optimization Functions in VFDs for Industrial Applications

   Master-uppsats, KTH/Elektrisk energiomvandling

   Författare :Qiang Dong; [2011]
   Nyckelord :;

   Sammanfattning : Electric motor systems are the most important types of loads which consume up to 70% of total consumed electricity in industry, so the reduction of energy  consumption in electric motor systems has become an important goal for all countries. In many of these applications, big energy savings are possible if the motors operate at variable speeds rather than at a fixed speed. LÄS MER
