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

    Author : Linus Eriksson; [2022]
    Keywords : Sub-synchronous control interaction SSCI ; damping of SSCI; DFIG; PSCAD; Power Oscillation Damper POD ; Harmonic Injection; Subsynkrona kontrollinteraktioner SSCI ; dämpning av SSCI; DFIG; PSCAD; Dämptillsats POD ; Harmonisk Injection;

    Abstract : Wind farms are commonly connected to the main grid through compensated lines which increases the power transfer capability of the line. Double Fed Induction Generator (DFIG) wind turbines in connection to compensated lines can experience Sub-Synchronous Control Interaction (SSCI) which can bring system quantities above allowed levels.

    Keywords : Multi-phase machine; asymmetrical six-phase induction machine; harmonic plane decomposition; indirect rotor field oriented control; parameter estimation; Flerfasmaskin; asymmetrisk sexfasinduktionsmaskin; harmonisk plan sönderdelning; indirekt rotorfältorienterad styrning; parameteruppskattning;

    Abstract : As a new type of machine, the multi-phase machine has the advantages ofhigher power rating, higher fault tolerance capability and more degrees offreedom to control compared with the traditional machine. Aiming at runninga multi-phase machine with different phase-pole configurations smoothly,a new method called harmonic plane decomposition is presented. READ MORE

  5. 4. Torque Ripple Analysis and Compensation of Servo Drives for Robot Application

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : August Millqvist; [2021]
    Keywords : Technology and Engineering;

    Abstract : Permanent magnet synchronous motors or PMSMs are commonly used in multiple applications, both in industry and commercial use. These motors have many pros when compared to other electrical machines but do present the issue of torque ripple, especially cogging torque. READ MORE

  6. 5. Modelling of air-gap harmonic torques and its impact on vibrations in electric drivetrains : Modelling interaction between electromagnetics and vibration of an electrical machine

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