  1. 1. Glyoxylic-Modified Lignin for Synthesis of Smart Elastomer and Composite Materials

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Xinyi Wei; [2023]
    Nyckelord :Lignin; lignin-based elastomer; nanocomposites; Lignin; ligninbaserad elastomer; nanokompositer;

    Sammanfattning : Sustainable development has become a global goal and the utilization of bioresources is a key way to achieve this crucial goal. Glyoxylic acid-functionalized lignin (GA-lignin) is one of the novel lignin derivatives extracted from beech wood (hardwood) and has great potential to be an industrially important bioresource.

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

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

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

    Sammanfattning : 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. LÄS MER

  4. 3. Developing Verification Models for Corona Discharge Suppression in High Voltage Capacitor Banks

    Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :Mohammadjavad Javadi; [2020]
    Nyckelord :Corona discharge; Suppression ring; High voltage capacitor banks;

    Sammanfattning : Due to the universal considerable population and economic growth rate, demands for energy have risen significantly over the past decade. This means that the integration of renewable energies in the power grid has escalated as well as requests for reactive power compensation, voltage stability, and mitigation of harmonic filters.
