  2. 21. Studies of safety and critical work situations in nuclear power plants : a human factors perspective

    Author : Lena Kecklund; Erik Hollnagel; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Safety; nuclear power; operators; work-related factors; performance; human error; annual outage; MTO; Psychology; Psykologi; psykologi; Psychology;

    Abstract : The purpose of this thesis was to develop and apply different approaches for analyzing safety in critical work situations in real work settings in nuclear power plants, and also to identify safety enhancing measures by using the framework of interaction between human, organizational and technical subsystems (MTO, man-technology-organization). A Cognitive Psychology as well as a Stress Psychology framework was used. READ MORE

  4. 22. On Harmonic Emission, Propagation and Aggregation in Wind Power Plants

    Author : Kai Yang; Roberto Langella; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric Power Engineering; Elkraftteknik;

    Abstract : The increasing use of wind energy is a global trend as part of the overall transition to a more sustainable energy system. By using modern technologies, the wind energy is converted into electric power which is transported to the consumers by means of the electric power system. READ MORE

  5. 23. Dynamic Processes and Active Power Control of Hydropower Plants

    Author : Weijia Yang; Per Norrlund; Torbjørn Kristian Nielsen; Uppsala universitet; []
    Keywords : Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : Hydro-electricity plays an important role in the safe, stable and efficient operation of electric power systems. Frequency stability of power systems refers to the ability to maintain steady frequency following a severe system upset resulting in a significant imbalance between generation and load. READ MORE

  6. 24. CO2 capture from oxy-fuel combustion power plants

    Author : Yukun Hu; Jinyue Yan; Erik Dahlquist; Mats Westermark; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 capture; oxy-fuel combustion; flue gas recycle; evaporative gas turbine; techno- economic evaluation;

    Abstract : To mitigate the global greenhouse gases (GHGs) emissions, carbon dioxide (CO2) capture and storage (CCS) has the potential to play a significant role for reaching mitigation target. Oxy-fuel combustion is a promising technology for CO2 capture in power plants. READ MORE

  7. 25. Voltage Support of Transmission Grids Using Resources Located in the Underlying Lower Voltage Networks : Unlocking the Potential of Distributed Generation Reactive Power Capabilities

    Author : Stefan Stanković; Lennart Söder; Andrew Keane; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reactive power support; voltage control; voltage stability; reactive power planning; inverter-based generation; active distribution networks; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The path to sustainable, fossil-free future leads to inevitable energy transition towards renewable energy sources. A part of this transition includes replacement of conventional transmission system connected power plants with distributed renewables plants such as wind power. READ MORE
