  1. 11. The impacts of series compensated EHV lines on distance protection, and a proposed new mitigation solution

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Syed Arif Ullah Shah; [2017]
    Keywords : Series compensation; metal oxide varistor; voltage inversion; current inversion; sub-synchronous oscillation; quadrilateral characteristic distance relay; digital high-pass filter; Seriekompensation; metalloxidvaristor; spänningsinversion; ströminversion; subsynkron oscillation; fyrsidig karakteristiskt distansrelä; digitalt högpassfilter;

    Abstract : Series compensation is extensively applied to the transmission lines to increase the power transfer capability of transmission lines, reduce transmission losses, improve voltage profiles, and improve power oscillation damping and transient stability of power systems. But it modifies the apparent impedance of the transmission lines during fault conditions and might cause the distance protection of transmission lines to encounter directional discrimination issues and reach problems.

  3. 12. MPC Design For Autonomous Drifting

    University essay from KTH/Reglerteknik

    Author : Corvin Kück; [2017]
    Keywords : ;

    Abstract : The goal of this thesis is to evaluate the performance of different controllers to keep a remotecontrolledvehicle in a sustained drift. A bicycle model and an empirical tyre model are used formodelling the vehicle. READ MORE

  4. 13. Self-Leveling pedestal for a movable Industrial Robot

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Roshan Arun N.S; [2016]
    Keywords : ;

    Abstract : ABBs kollaborativa robot YUMI, är en industrirobot med sju frihetsgrader. Den har två armar, vilka är avsedda att samverka med människor i arbete. Roboten var ursprungligen avsedd att monteras på ett bord, men olika tillämpningar och krav för förflyttning av sådana samarbetsrobotar motiverade en ny rörlig piedestal. READ MORE

  5. 14. Detection and interpretation of weak signals

    University essay from Linköpings universitet/Interaktiva och kognitiva system

    Author : Richard Wiik; [2016]
    Keywords : resilience; stability; SyReS; nuclear; Human Performance; Human factors; weak signals; pre-job briefing; human performance tools; drift into failure; drift; views on safety;

    Abstract : Managing safety at a nuclear power plant is about a complex system with demanding technology under time pressure where the cost of failure is exceptionally high. Swedish nuclear power plants have over the last few years introduced Pre-job Briefing and other so called Human Performance Tools to advert errors and strengthen control. READ MORE

  6. 15. Global Analysis and Structural Performance of the Tubed Mega Frame

    University essay from KTH/Betongbyggnad

    Author : Han Zhang; [2014]
    Keywords : Tubed Mega Frame; high-rise buildings; ETABS; wind load; design response spectrum;

    Abstract : The Tubed Mega Frame is a new structure concept for high-rise buildings which is developed by Tyréns. In order to study the structural performance as well as the efficiency of this new concept, a global analysis of the Tubed Mega Frame structure is performed using finite element analysis software ETABS.
