  1. 31. Analys av mätdata från nätstationer

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Martin Eklöf; [2014]
    Nyckelord :Fortum; mätdata; nätstation;

    Sammanfattning : Fortum has in a pilot project installed metering equipment with wireless communication in secondary substations in Stockholm. So far, the collected data are used only in specific projects. This master thesis was carried out at Fortum Distribution AB in Stockholm during 2013. LÄS MER

  3. 32. Underlag till energieffektiviserande åtgärder i nätstationer

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Sebastian Krantz; [2014]
    Nyckelord :elkraft; elkraftingenjör; elkraftsingenjör; nätstationer; nätstation; elnät; energiförluster; energieffektivisering; transformatorförluster;

    Sammanfattning : Umeå Energi are working towards a goal, that in the year of 2018, they will be completely climate neutral. As a part of this, one target is to reduce their grid losses by 4 % of the 2012 level, which corresponds to an overall reduction of the grid losses of just over 1.7 GWh. LÄS MER

  4. 33. Magnetfält alstrade kring nätstationer i samband med lokaldistribution av elkraft : Magnetic fields generated by electrical substations during distribution of electric power

    Kandidat-uppsats, Institutionen för datavetenskap, fysik och matematik, DFM

    Författare :Fredrik Strömberg; [2012]
    Nyckelord :Electrical substation; electromagnetism; transformer; radiation measurements; Nätstation; elektromagnetism; transformator; strålningsmätning;

    Sammanfattning : Abstract: This report covers primarily the work of documenting electromagnetic fields generated by one of the later parts in the electrical power distribution chain: The electrical substation, wherein 10 kV is transformed to 400 V for use by private consumers. Thus it is one of the most widespread and frequently occurring parts in the Swedish power grid and of particular interest, as electrical substations are found everywhere in populated areas, often in close vicinity to people and animals.
