    Abstract : Popular Abstract in Swedish Återkoppling är en fundamental princip inom reglertekniken. Genom att mäta vissa variabler kan andra påverkas så att ett system uppför sig på önskat vis. Denna doktorsavhandling behandlar två typer av återkoppling: reläåterkoppling och flervariabel återkoppling. READ MORE

  3. 3. Tools for Autonomous Process Control

    University dissertation from Department of Automatic Control, Lund Institute of Technology (LTH)

    Author : Anders Wallén; Lunds universitet.; Lund University.; [2000]

  4. 4. The Frequency of the Frequency On Hydropower and Grid Frequency Control

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Linn Saarinen; Uppsala universitet.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydropower; frequency control; governors; power system stability; inertia; primary control; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : Variations in the electricity consumption and production connected to the power system have to be balanced by active control. Hydropower is the most important balancing resource in the Nordic system, and will become even more important as the share of variable renewable energy sources increases. READ MORE
