  1. 1. Unwillingly Advised : A field study on the dynamics of policy advice in developmentcooperation

    Master-uppsats, Uppsala universitet/Statsvetenskapliga institutionen

    Författare :Linnéa Åström Tolf; [2019]
    Nyckelord :policy advice; development cooperation; SCL model; postcolonialism; critical postcolonial theory; technical assistance.;

    Sammanfattning : While development cooperation largely consists of policy advice, the suggestions and inputs on development that policymakers in the Global South receive from donors and other international actors, little research exists on what makes policy advice useful to these policymakers. The aim of this study was to find out why policymakers in the Global South find some advice useful and some not. LÄS MER

  3. 2. Digital secondary substations with auto-configuration of station monitoring through IEC 61850 and CIM

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Johan Wistedt; [2018]
    Nyckelord :IEC61850; RTU communication; HMI; grid protection; CIM; Network information system; intelligent electrical devices; secondary substation;

    Sammanfattning : This thesis explore the possibility to automate a process for configuration of secondary substations monitoring and control. By using a network information system (NIS), information of secondary substations can be extracted, such as feeder naming, primary equipment type, rating and model. LÄS MER

  4. 3. Strömbegränsare i synkrongeneratorer : En studie av strömbegränsarmodeller i PSS/E

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Axel Thornström; [2016]
    Nyckelord :Power systems; overexcitation limiter; stator current limiter; dynamic simulation; PSS E; automatic voltage regulator; Kraftsystem; fältströmbegränsare; statorströmbegränsare; strömbegränsare; PSS E; spänningsreglering; dynamisk simulering;

    Sammanfattning : It is well known that a crucial factor determining the transmission capacity with regards to the voltage stability limit of a stressed power system, is the limitation of field and stator current of overexcited generators. These limiters are commonly referred to as overexcitation limiters (OEL) and stator current limiters (SCL). LÄS MER
