  1. 21. Passive Island Detection of Microgrid by Grid Forming Inverter

    Författare :Shoaib Salim Inamdar; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microgrid; passive island detection; Grid forming; rotor angle deviation; non-detection zone; inertia; virtual synchronous machine; voltage vector shift.;

    Sammanfattning : The supply reliability of a local grid will be improved if the local grid is managed as a microgrid, with the ability to operate in island mode when the main grid is temporarily unavailable. This thesis focuses on microgrids powered by inverter-based resources (IBRs), one or several of which need to be equipped with grid forming (GFM) capability for establishing and controlling the voltage and frequency of the microgrid during island operation.

  2. 22. Numerical Study of Fluid-Structure Interaction with Application to Oscillating Cylinders

    Författare :Mikhail Lazarkov; Strömningsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lock-in.; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik; synchronization; flow-induced vibration; LES; Volume of Solid method; Virtual Boundary method; vortex-shedding; confined cylinder; Fluid-structure interaction; wake;

    Sammanfattning : The problem of fluid-structure interaction, occurring in many industrial and engineering applications, are of great importance, since interaction of a flow and a structure in it can lead to serious damages of the structure. The fluid-structure interaction gives rise to a variety of different physical phenomena such as flow-induced vibration, noise generation, etc. LÄS MER

  3. 23. On intelligent automation systems

    Författare :Endre Erös; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automated planning; Automation; testing and coverability.; modeling; virtual preparation and commissioning; robot operating system;

    Sammanfattning : Developing automation systems that are capable of handling dynamic and unpredictable situations is a challenging task, as it requires adapting to a changing environment and managing potentially unforeseen action outcomes. In contrast to traditional automation, where control code is explicitly pro- grammed, a model-based approach might be a more appropriate solution for automating such systems. LÄS MER

  4. 24. Exploring trade-offs between Latency and Throughput in the Nostrum Network on Chip

    Författare :Erland Nilsson; Johnny Öberg; Daniel Wiklund; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Micro electronics; Nostrum; Network on Chip; NoC; on-chip networks; micro networks; Nätverk på kisel; Nätverk på chip; Other electrical engineering; electronics and photonics; Övrig elektroteknik; elektronik och fotonik;

    Sammanfattning : During the past years has the Nostrum Network on Chip (NoC) been developed to become a competitive platform for network based on-chip communication. The Nostrum NoC provides a versatile communication platform to connect a large number of intellectual properties (IP) on a single chip. LÄS MER

  5. 25. Methods for Early Model Validation : Applied on Simulation Models of Aircraft Vehicle Systems

    Författare :Magnus Carlsson; Johan Ölvander; Hampus Gavel; Lars Eriksson; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Simulation  models of physical systems, with or without control software, are widely used in the aeronautic industry in applications ranging from system development to verification and end-user training. With the main drivers of reducing the cost of physical testing and in general enhancing the ability to take early model-based design decisions, there is an ongoing trend of further increasing the portion of modeling and simulation.
