    Abstract : Two important physical aspects that determine the performance of a running train are the total running resistance that acts on the whole train moving forward, and the available adhesion (utilizable wheel-rail-friction) for propulsion and breaking. Using the measured and available signals, online identification of the current running resistance and available adhesion and also prediction of future values for a distance ahead of the train, is desired.

  4. 3. Modelling of Ice Storms and their Impact on a part of the Swedish Transmission Network

    University essay from KTH/Elektriska energisystem

    Author : Jesper Ahlberg; [2006]
    Keywords : ;

    Abstract : In this master thesis a weather model to simulate an ice storm is developed. Precipitation, wind and movement are modelled by mathematical functions to create a realistic model. The weather model is used to calculate wind and ice loads on power lines. Two dierent models for the ice accretion on the power lines are used and compared. READ MORE
