  2. 1. Model-Implemented Fault Injection for Robustness Assessment

    Author : Rickard Svenningsson; Martin Törngren; Sasikumar Punnekkat; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fault Injection; Model-Implemented Fault Injection; Robustness; Assessment; ISO 26262; ISO 61508; Software;

    Abstract : The complexity of safety-related embedded computer systems is steadilyincreasing. Besides verifying that such systems implement the correct functionality, it is essential to verify that they also present an acceptable level of robustness. READ MORE

  4. 2. Faults and their influence on the dynamic behaviour of electric vehicles

    Author : Daniel Wanner; Annika Stensson Trigell; Lars Drugge; Jonas Sjöberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fault classification; vehicle dynamics; electric vehicle; failure; fault-tolerant control; reconfiguration; fault handling; Järnvägsgruppen - Fordonsteknik; Järnvägsgruppen - Fordonsteknik;

    Abstract : The increase of electronics in road vehicles comes along with a broad variety of possibilitiesin terms of safety, handling and comfort for the users. A rising complexityof the vehicle subsystems and components accompanies this development and has tobe managed by increased electronic control. READ MORE

  5. 3. Fault location in resonant earthed medium voltage distribution systems

    Author : Md Zakaria Habib; Nathaniel Taylor; Mohamed F. Abdelfattah; Matti Lehtonen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical distribution; Distribution network; Reliability; SAIDI; Fault location; FL; Fault passage indicator; FPI; Compensated neutral; Resonant earthing; Resonant grounding; Petersen coil; Arc suppression coil.; Distributionsnät; Tillförlitlighet; Fellokalisering; FL; Felpassageindikation; FPI; Kompenserat nät; Spoljordat nät; Petersenspole.; Electrical Engineering; Elektro- och systemteknik;

    Abstract : A major challenge in electric distribution systems is to increase the reliability of the electricity supply in an economical way. At the final medium-voltage level in the system, such as 10 kV or 20 kV, a single feeder may supply tens of medium/low-voltage transformers and hundreds of customers, with many branches of lines and cables where faults can occur.

  6. 4. A Fault Detection Framework Using Recurrent Neural Networks for Condition Monitoring of Wind Turbines

    Author : Yue Cui; Lina Bertling; Pramod Bangalore; Bikash C Pal; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; asset management; condition monitoring; fault detection; preventive maintenance; recurrent neural networks; two-stage threshold; wind power; kapitalförvaltning; underhållsstyrning; tillståndsövervakning; feldetektering; förebyggande underhåll; återkommande neurala nätverk; tvåstegs tröskel; vindkraft; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The global energy system is experiencing a transition to a sustainable system with ambitious targets for increased use of renewable energy. One key trend for this transition has been the large introduction of wind power and integration into the electricity grid. READ MORE

  7. 5. A Bayesian approach to fault isolation with application to diesel engine diagnosis

    Author : Anna Pernestål; Bo Wahlberg; Stefan Arnborg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bayesian probability; fault diagnosis; fault isolation; Bayesian inference; Automatic control; Reglerteknik;

    Abstract : Users of heavy trucks, as well as legislation, put increasing demands on heavy trucks. The vehicles should be more comfortable, reliable and safe. Furthermore, they should consume less fuel and be more environmentally friendly. For example, this means that faults that cause the emissions to increase must be detected early. READ MORE
