  4. 2. Vibrant bodies of swirling flow : On the limits of mechanical power transformation

    Author : Ida Jansson; Don-Hyun Kim; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : This thesis pinpoints the intertwined nature of inertia. A vibrant body of a swirling flow is neither just a flow nor a body. It is both. READ MORE

  6. 4. Multiple Aspects of Dynamic Rating in the Power System

    Author : Seyede Fatemeh Hajeforosh; Math Bollen; Sarah Rönnberg; Alfredo Vaccaro; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic rating; Transmission lines; Overload Protection; Stochastic analysis; Hosting capacity; Transformers; Electric Power Engineering; Elkraftteknik;

    Abstract : Increased consumption and increased use of renewable energy make overhead lines and transformers more often congested. Dynamic rating (DR) uses a time-depending maximum permissible current instead of a long-term-fixed rating; it is an effective solution to upgrade the capacity of existing grid assets to minimize this congestion.

  7. 5. Dynamic Rating with Applications to Renewable Energy

    Author : Kateryna Morozovska; Patrik Hilber; Tor Laneryd; Hans Ezz Edin; Adamantios Marinakis; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic rating; dynamic line rating; dynamic transformer rating; power transformers; power system optimization; wind farm planning; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Dynamic rating (DR) of power components is a method for assessing real-time capacity of large scale power transmission and distribution devices (commonly: transmission lines, power transformers, underground cables) and using this knowledge for adjusting loading limits of these components. Dynamic rating of power lines or dynamic line rating (DLR) is a pioneering technology in the area of dynamic rating.
