  3. 2. Power Electronic Enhanced Distribution Transformer : Seamless Voltage Regulation with Extended Functionalities

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

    Author : Nils Johansson; [2022]
    Keywords : Hybrid distribution transformer; Power converters; Voltage control; Hybrid power system; Reactive power; Hybrid distrubitionstransformator; Effektomvandlare; Spänningskontroll; Hybrida elnät; Reaktiv effekt;

    Abstract : On-load tap changers and static synchronous compensators (STATCOM) are the main components for voltage regulation and power quality optimization in the power system. STATCOMs are used in both industrial applications and utility to stabilize the grid and reduce downtime. READ MORE

  5. 4. 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

  6. 5. An MMC-based topology with Dual-Active-Bridge power channels for load balancing in 50 Hz-railway applications

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Andreas Zafeiropoluos; [2017]
    Keywords : Power electronics; STATCOM; MMC; power channel; power quality; negativesequence compensation; high-speed trains;

    Abstract : The purpose of this thesis report is to investigate challenges related to railway electrification. Inac-railway systems, trains are most often single-phase loads, which can create significantunbalances in the grid, when fed directly from two adjacent phases. READ MORE
