  1. 21. Condition-based Failure Rate Modelling for Individual Components in the Power System

    Författare :Jan Henning Jürgensen; Patrik Hilber; Lars Nordström; Thomas Welte; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Asset management; condition monitoring; diagnostic measures; failure rate; failure rate modeling; transformer diagnostics; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The electrical power grid is one of the most important infrastructures in the modernsociety. It supplies industrial and private customers with electricity and supportsother critical infrastructures such as the water supply. Thus, it is significant that the power grid is a reliable system.

  3. 22. Modeling of Combustion, Mixing and Heat Transfer in Oxy-Fuel CFB Power Plants

    Författare :Sadegh Seddighi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : An important contribution to anthropogenic emissions of CO2 is from electricity generation, i.e. emissions from large fossil fuelled power plants. Carbon Capture and Storage technologies offer the possibility for continued use of fossil fuels while almost eliminating the CO2 emissions. LÄS MER

  4. 23. Climate impacts of woody biomass use for heat and power production in Sweden

    Författare :Torun Hammar; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Global warming is a result of human-induced greenhouse gas emissions, primarily from fossil fuel use, but also from land use changes. To mitigate climate change, fossil fuel-based energy systems need to be replaced with alternative energy sources. LÄS MER

  5. 24. Assessment of energy storage systems for power system applications based on equivalent circuit modeling

    Författare :Cong-Toan Pham; Daniel Månsson; Alfred Rufer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy storage system; Assessment; Equivalent circuit model; Suitability; ; Electrical Engineering; Elektro- och systemteknik; Energy Technology; Energiteknik;

    Sammanfattning : Climate change triggered the rethinking of our current energy system. A restructuring is necessary and in progress with the goal to improve our energy supplychain in efficiency and sustainability. This has led to the increased use of renewable energy sources such as solar and wind power. LÄS MER

  7. 25. Potential of fly ashes for neutralisation of acid mine drainage from coal mine waste rock

    Författare :Asif Qureshi; Josef Mácsik; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Sammanfattning : Many countries around the world use coal as fuel for the purpose of power generation. The extraction of coal produces large volumes of waste rock (WR) that are sometimes sulphide rich (principally containing iron sulphides such as pyrite (FeS2) and pyrrhotite (Fe1-xS)), with varying quantities of trace elements such as As, Si, Cu, Zn, Ni, Co, Mo and Cr etc).
