  1. 36. Sensorless Control of Synchronous Machines in Python Using Signal Injection : An implementation of a High-Frequency Square-Wave Injection Algorithm on a Linear and Non-Linear Synchronous Machine Model in open-source Software Motulator

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

    Author : Simon Lundberg; [2022]
    Keywords : High-frequency signal injection; Permanent Magnet Synchronous Motor; sensorless speed control; Synchronous Reluctance Machine; square-Wave injection; Fyrkantsvågsinjektering; högfrekvent signalinjektering; Permanentmagnetsmotor; sensorlös hastighetskontroll; synkron reluktansmotor;

    Abstract : The importance of accurately controlling the speed and torque of Synchronous Machines (SMs) in industry, transportation, aerospace, to name a few, can not be overstated. The driving unit to control the machines are called Variable Speed Drives (VSDs) and they can be designed in many different ways. READ MORE

  3. 37. Microsatellite Constellation for Wildfire Monitoring

    University essay from KTH/Geoinformatik

    Author : Citlali Bruce Rosete; [2022]
    Keywords : microsatellite; shortwave infrared sensor; active fire monitoring; burned area detection; satellite constellation; mikrosatellit; kortvågig infraröd sensor; aktiv brandövervakning; detektion av brandhärjat område; satellitkonstellation;

    Abstract : I flera års tid har antalet svåra och okontrollerade skogsbränder ökat i antal. Det finns ett behov av att detektera skogsbränder med hjälp av satelliter som har högre tidsupplösning samt högre geometrisk upplösning än de satelliter som är i bruk idag. READ MORE

  4. 38. Asynchronous Multi-Agent Games With Imperfect Information and Knowledge Based Strategies

    University essay from KTH/Datavetenskap

    Author : Daniel Hartler; Jakob Ewaldsson; [2022]
    Keywords : ;

    Abstract : This project investigates abstract games, which model real life tasks that are projected onto graphs. Strategic planning within these games provide a way of coordinating the participants in order for them to reach some desired objective. READ MORE

  5. 39. The Biogeographical Extent and Global Synchronicity of the Late Miocene Reticulofenestra pseudoumbilicus Paracme

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Joseph Asanbe; [2022]
    Keywords : late Miocene; biogenic bloom; nannofossil biostratigraphy; paleo-productivity; Reticulofenestra size variation;

    Abstract : Previous biostratigraphic studies in the Indian Ocean, equatorial Pacific, Atlantic Ocean and the Caribbean Sea document the temporal disappearance of Reticulofenestra pseudoumbilicus in the late Miocene (Tortonian age). This interval has been subsequently defined as the R. pseudoumbilicus paracme. READ MORE

  6. 40. Frequency Stability of Power Electronic Based Power System with 100% Renewable Energy.

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

    Author : Abdullah Albalali; [2022]
    Keywords : energy storage; frequency control; synchronous generators; distributed power generation; virtual synchronous machine VSM ; PSCAD.; energilagringssystem; frekvenskontroll; synkrona generatorer; distribuerad kraftproduktion; virtuell synkron maskin; PSCAD.;

    Abstract : The modern power system is aiming to progress away from conventional synchronous machine  based power generation towards converter dominated system that leads to extensively high penetration of renewable energy such as wind and PV. This transition of modern power system toward converter based renewable energy comes with new challenges as the conventional synchronous generation is being replaced by converter based power system (CBPS).
