    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Communication networks; digital signal processing; digital substation; field-programmable gate array; filter design; IEC 61850; IEC 61869; power system protection; substation automation; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Future power systems will be dominated by power electronic (PE) converter connected generation. This trend is primarily driven by the increasing penetration of wind power as well as the increasing integration of photovoltaic (PV) based generation. LÄS MER

  4. 3. On Industrial Automation Software Components

    Författare :Oscar Ljungkrantz; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; IEC 61131; Programmable Logic Controller PLC ; IEC 61499; formal verification; Manufacturing automation software; software reusability; Reusable Automation Component RAC ; software specification;

    Sammanfattning : This thesis deals with Programmable Logic Controller (PLC) programs in the manufacturing industry, that is to say programs that coordinate robots and machines. The last years there has been increased competition and shorter life-cycles of many mass-produced products. LÄS MER

  5. 4. Magnetic Properties of Epitaxial Metal/Oxide Heterostructures

    Författare :Tobias Warnatz; Björgvin Hjörvarsson; Fridrik Magnus; Vassilios Kapaklis; Stuart S.P. Parkin; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fe MgO; interlayer exchange coupling; anisotropy; IEC; superlattice; multilayer; polarized neutron reflectometry; PNR; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Sammanfattning : The work in this dissertation is devoted to tailoring and studying magnetic properties of epitaxial metal/oxide heterostructures. The aim is to understand the fundamental principles governing these properties and how they affect each other. The acquired knowledge can prove useful for the development of future spintronic devices. LÄS MER

  7. 5. On Formal Methods in Development of Control Logic Using IEC 61499

    Författare :Goran Cengic; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Modeling; Synthesis; Verification; Formal Methods; Supervisory Control Theory; IEC 61499; Control Logic Development;

    Sammanfattning : In the present global economy the manufacturing industry is faced with the challenges that need to be overcome in order to remain competitive and avoid outsourcing. One of the challenges is the efficient development of the control logicfor the distributed control systems that are often used to control the manufacturing equipment in the industry. LÄS MER
