  1. 6. 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heating has traditionally been done using resistive heating wires mounted to the stock rail, but the technology is outdated and generally exhibits low efficiency and performance.

    Abstract : The transition towards renewable energy and electrification is expected to accelerate in the coming decades. This change is being studied by several actors, in Sweden most notably by Svenska kraft- nät, the Swedish TSO. READ MORE

  3. 8. Evaluating Security Mechanisms of Substation Automation Systems

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

    Author : Ziyang Zhou; [2023]
    Keywords : Substation automation system; Threat modeling; Meta attack language; Stationsautomationssystem; Hotmodellering; Meta attack language;

    Abstract : Substations are important components for transforming voltage and distributing power in electrical infrastructure. Modern substations are usually automated by substation automation systems, which offload the work of operators and reduce potential human error. READ MORE

  4. 9. Sensorless Hybrid Field-Oriented Control Two-Phase Stepper Motor Driver

    University essay from Linköpings universitet/Reglerteknik

    Author : Emil Lydell; [2023]
    Keywords : Stepper motor; Field-Oriented Control; FOC; Driver; Two-Phase; 2-Phase;

    Abstract : Hybrid stepper motors are small electrical motors with high torque production, compared with other electrical motors of the same size. Hybrid stepper motors are reliable in open-loop systems, in Sinusoidal mode, but with a drawback of high power consumption. READ MORE

  5. 10. Addressing Water Scarcity in La Guajira: A Comparative Analysis of Four Water Systems

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Johan Hedstrand Welander; [2023]
