  1. 1. INDUCTIVE RAILWAY SWITCH POINT HEATING : Improved control algorithm and phase compensation analysis for an inductive turnout heating system, and comparison with a resistive heating system

    University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Author : Erik Nordlund; [2023]
    Keywords : Inductive switch point heating; Turnout heating; railway turnout heating; Inductive heating;

    Abstract : Railway turnout heating is essential during the winter because snow and ice can hinder the movement of the switch. In Sweden, heating has traditionally been done using resistive heating wires mounted to the stock rail, but the technology is outdated and generally exhibits low efficiency and performance.

  3. 2. Fault diagnosis of a variable pole-phase motor

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Claes Henriksson; [2023]
    Keywords : Multiphase machine; variable pole-phase machine; fault diagnosis; switch fault; phase fault; harmonic plane decomposition; wound independently controlled stator coil machine; Multifasmaskin; variabel polfasmaskin; feldiagnosticering; brytarfel; fasfel; harmonic plane decomposition; WICSC-maskin;

    Abstract : Wound Independently Controlled Stator Coil (WICSC) machines are a novel type of multiphase machine with the ability to change its pole-phase configuration during operation. This enables improved post-fault control and thus prolonged continuous operation. READ MORE

  4. 3. Substation digitalization and fault isolation : A study of the influence of degree of digitalization to regulatory indicators in the power grid

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Ili Atalla; [2023]
    Keywords : ;

    Abstract : With changes in the energy sector, more demand is set on the power grid as electricity consumption is seen to increase and more decentralized renewable energy production is connecting to the grid. Svenska Kraftnät, electric system transmission operator in Sweden, describes the importance a more secure operation of the power system. READ MORE

  5. 4. Modeling fault probability in single railroad turnouts in Eastern Region, Sweden, with the use of logistic regression models : A step from preventive to predictive preventive maintenance in railway maintenance planning

    University essay from KTH/Transportplanering

    Author : Filipp Zarov; [2019]
    Keywords : maintenance planning; railway turnouts; malfunction probability modeling; object-oriented databases; logistic regression models; underhållsplanering; spårväxlar; felsannolikhet modellering; objektorienterad databas; logistiska regressionsmodeller;

    Abstract : Turnouts are an important part of railway infrastructure for two reasons: infrastructure andmaintenance. For the infrastructure they provide the flexibility to allow the formulation and branchingof railway network and for maintenance they consume a large part of maintenance budget and have aprominent place in maintenance planning policy and activities.

  6. 5. Evaluating performance of a fault-tolerant system that implements replication and load balancing

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Oskar Gustafsson; Rickard Hellenberg; [2017]
    Keywords : ;

    Abstract : Companies and organizations increasingly depend on their computer systems to help them in their work. This means that the availability of these computer systems becomes even more important as organizations are increasingly dependent on it to function. Therefore, fault tolerance needs to be considered when designing a computer system. READ MORE
