  2. 1. Characterising Resistance to Electrical Treeing in New XLPE-Based Materials for High-Voltage Cables

    Author : Anette Johansson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electrical treeing; partial discharge; cross-linked polyethylene; voltage stabiliser; degradation; power cables;

    Abstract : This work looks into electrical treeing in cross-linked polyethylene-based materials (XLPE), where the ability to resist tree development is considered as an indicator of improved applicability for insulation in high voltage power cables. The thesis presents results of a twin PhD project involving joint work of two students. READ MORE

  4. 2. Voltage Stabilisers for XLPE Cable Insulation

    Author : Villgot Englund; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polyethylene; insulation; electrical treeing; degradation; cable; stabilisers; XLPE;

    Abstract : The demand for energy in the Western world has istorically increased steadily and a steady increase is forecasted for the next decades. This steady increase together with the huge merging markets in India and China are setting new standards for the energy transmission. READ MORE

  5. 3. The Dynamic Impact of Large Wind Farms on Power System Stability

    Author : Katherine Elkington; Mehrdad Ghandhari; Ana Estanqueiro; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : As the installed capacity of wind power increases across the world, its impact on power systems is becoming more important. To ensure the reliable operation of a power system which is significantly fed by wind power, the dynamics of the system must be understood. READ MORE

  6. 4. Modelling and Control of Doubly Fed Induction Generators in Power Systems : Towards understanding the impact of large wind parks on power system stability

    Author : Katherine Elkington; Lennart Söder; Evert Agneholm; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric power engineering; Elkraftteknik;

    Abstract : The rapid development of wind power technology is reshaping conventional power grids in many countries across the world. As the installed capacity of wind power increases, its impact on power grids is becoming more important. READ MORE
