  1. 1. Radio Environment Compensation in a Narrowband IoT Positioning System : Using Radio Signal Metrics Between Stationary Devices

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

    Author : Elin Berglund; [2023]
    Keywords : Positioning; IoT; machine learning; range estimation; Positionering; IoT; maskininlärning; avståndsuppskattning;

    Abstract : The Internet of Things (IoT) has emerged as a powerful tool for meeting our need to collect information about and interact with our environments. One important aspect of this technology is positioning which imposes requirements on both the energy consumption and the arrangement of the systems. READ MORE

  3. 2. Cross coupling in a two-axis control system for stabilized platforms

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

    Author : Bill Lavebratt; [2022]
    Keywords : MIMO; Modeling; Two-axis gimbal system; Decoupler; Inner loop disturbance compensation; Control theory.;

    Abstract : Inertial stabilized platforms consisting of a two-axis gimbal assembly are often modelled as two independent SISO systems, describing the dynamics of the elevation axis and the azimuth axis respectively. In reality the state of the elevation channel and the state of the azimuth channel affect each other. READ MORE

  4. 3. Voltage Stability and Reactive Power - Introduction of Intermittent Renewable Energy Sources in a Power System

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

    Author : Erik Hagström; Tobias Jansson; [2022]
    Keywords : Voltage Stability; Reactive Power; Renewable Energy; Wind Power; Power Flow Analysis; MATPOWER;

    Abstract : The electricity demand increases rapidly, and in order to mitigate climate change the power production needs to be renewable and free from green house gas emissions. When solar and wind power are introduced in the system, voltage instability might become a problem. READ MORE

  5. 4. Power Electronic Enhanced Distribution Transformer : Seamless Voltage Regulation with Extended Functionalities

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

    Author : Nils Johansson; [2022]
    Keywords : Hybrid distribution transformer; Power converters; Voltage control; Hybrid power system; Reactive power; Hybrid distrubitionstransformator; Effektomvandlare; Spänningskontroll; Hybrida elnät; Reaktiv effekt;

    Abstract : On-load tap changers and static synchronous compensators (STATCOM) are the main components for voltage regulation and power quality optimization in the power system. STATCOMs are used in both industrial applications and utility to stabilize the grid and reduce downtime. READ MORE

  6. 5. Pre-study of optical LED units for shunting signals

    University essay from KTH/Hälsoinformatik och logistik

    Author : Tobias Adolfsson; Axel Dellenby; [2021]
    Keywords : LED - Light Emitting Diode; Booster Converter; MLCC - Multi-layer capacitor; ESR - Equivalent Serie Resistance; OU - Optical Unit; Reactive compensation; LED - lysdiod; step-up omvandlare; MLCC - flerskiktskeramisk kondensator; ESR - ekvivalent serie motstånd; OU - optiskt enhet; reaktiv kompensering;

    Abstract : Alstom wanted to investigate the possibility of adapting its light emitting diode (LED) technology for shunting signals in train traffic. The LED technology uses 50V, but Alstom wants to adapt it for 12V. The LED technology is energy efficient but needs to be adapted for existing signal interlocking by drawing a higher current.
