    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

  4. 3. New Topology for STATCOM

    University essay from KTH/Elkraftteknik

    Author : Marta Ibáñez Sánchez; [2017]
    Keywords : STATCOM; Modular Multilevel Converter; Chain-Link; negative sequence capability; common dc-link; bi-directional switches;

    Abstract : Static compensators (STATCOM) based on high-power converters are widely used for utilitiesand industrial applications in order to enhance the power system reliability. Nowadays,the Chain-Link Modular Multilevel Converter is the best solution for such applications,providing high eciency and reliability, and good harmonic performance. READ MORE
