  1. 11. Current measurements of low-power battery driven devices

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Marcus Wahlberg; [2022]
    Nyckelord :Current meter; current measurement; shunt resistor; auto-range; current-range;

    Sammanfattning : A current meter has been designed, intended for surveillance of low-power battery driven devices with a large dynamic range in their current consumption. Among such devices may, for example, be nodes in a wireless sensor network (WSN). LÄS MER

  3. 12. Optimal collection grid and transmission line topology for the grid connection of an offshore multi-source park.

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Alfred Nerby; [2022]
    Nyckelord :Renewable; Wind; Solar; multi-source; park; collection grid; substation; transmission; HVAC; HVDC; converters; shunt reactors; transformer; losses; CAPEX; OPEX;

    Sammanfattning : As spacial restrictions become more and more of an issue for renewable energy parks onshore, more developers are turning offshore to develop future production. The desire for a diversity of energy sources combined with a desire to utilize space efficiently has sparked an interest in renewable energy parks where more than one energy source occupy the space.

  4. 13. 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

  5. 14. Model verification and common mode current analysis of grid connected three phase two level converters

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Simon Lindvall; Richard Haraldsson; [2021]
    Nyckelord :active filter; EMC; EMI; converter; common mode; differential mode; shunt active filter; parasitic elements; Technology and Engineering;

    Sammanfattning : In this Master’s thesis an in-depth model of a shunt active filter for high frequency analysis is constructed. The purpose is to enable analysis of higher frequency behavior reaching 1MHz. Using the high frequency model, common mode currents can be simulated. LÄS MER

  7. 15. Review and Design Adaptations of a SrCl2-NH3 bench-scale Thermochemical Heat Storage system

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)
