  1. 1. Investigation of Variable Speed Technology when Converting Hydropower Kaplan Turbines into Fixed Propeller Turbines

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Johannes Ansved; [2022]
    Keywords : hydropower; variable speed; kaplan; turbines; model; simulation;

    Abstract : With an evolving energy system, an increased flexibility is necessary, placing additional demand on hydropower plants. New technology, in particular full size frequency converters (FSFC) and doubly fed induction machines (DFIM), allows hydropower turbines to run at different speeds than originally designed, thus making the turbine more flexible.

  3. 3. Development of an experimental six-phase induction machine drive

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Adam Bianchi; [2021]
    Keywords : Asymmetrical six-phase induction machine; indirect rotor field oriented control; machine rewinding; multiphase electrical machines; PCB design; speed control; the star of the slot .; Asymmetrisk sexfasig asynkronmaskin; flerfasiga elektriska maskiner; hastighetsreglering; indirekt rotorfälts orienterad reglering; kretskorts design; maskinomlindning; the star of the slot .;

    Abstract : Electrical machines with more than three phases are usually called multiphase electrical machines and they can have several advantages compared to conventional three-phase electrical machines such as a lower content of space-harmonics, lower torque ripple and better fault tolerance. This degree project involves rewinding of a three-phase induction machine into an asymmetrical six-phase machine. READ MORE

  4. 4. Electromagnetic Sizing of Axial-Flux Induction Machines and Experimental Validation

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Leonardo Colombo; [2021]
    Keywords : Sizing algorithm; Double-stator axial-flux machines; Finite-element method; Material identification.; Dimensioneringsalgoritm; Dubbel statoriska axiella flödesinduktionsmaskiner; Finita-element metoden; Material-identifieringsprocedurer;

    Abstract : With a rising drive towards greener means of transportation, electrical machines for propulsion are becoming a scientific field of major interest. In particular, part of the research studying these devices focuses its efforts on axial-flux machines, which compared to radial-flux machines can offer a better length-to-diameter ratio and higher torque arm for similar ratings.

  5. 5. Condition monitoring of induction machines using a signal injection technique

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Sathiya Lingam Senthil Kumar; [2020]
    Keywords : Condition monitoring; fault detection; fault diagnosis; stator winding fault; inter-turn fault.; Tillståndsövervakning; feldetektering; feldiagnos; statorlindningsfel; kortslutning mellan varv.;

    Abstract : Condition monitoring techniques can be employed to enhance reliability of electric machinery. The stator winding fault is one of the dominant causes for the failure of induction machines. In this work, the condition monitoring of an inverter-fed induction machine using high-frequency signal injection based technique is investigated. READ MORE
