1. 6. Analysis of Resin Impregnated Non-woven : In collaboration with Hitachi Energy

   University essay from Uppsala universitet/Institutionen för materialvetenskap

   Author : Ahmed Abdulkareem Najm Al-Saedi; Anders Hedenfeldt; Andrea García; Anna-Karin Kron; Cornelia Bergström; Lova Källkvist; [2022]
   Keywords : resin impregnated non-woven; bushings; composite; resin impregnated paper; tensile; bending; permeability; mechanical properties;

   Abstract : High voltage bushings are the most critical components of power transformers. A common material used in bushings is resin impregnated paper (RIP). Hitachi Energy is investigating whether this can be replaced with a new material, resin impregnated non-woven (RIN). READ MORE

3. 7. Commissioning of a FPGA/DSP unit for Centralized Control of a Variable Phase Pole Multiphase Machine

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

   Author : Jonas Hansson; [2022]
   Keywords : Harmonic Plane Decomposition; Multiphase Electrical Machine; Wound Independently-Controlled Stator Coils; System on a chip; Control Implementation; Hardware Design ; Motorstyrning; Asynkronmotor; Multifasmaskin; Programmering; Systemkrets; Hårdvarukonstruktion;

   Abstract : Multiphase Electrical Machines (MPEMs) with variable phase-pole configurations have recently gained interest as it offers advantages such as a larger operating range and improved fault tolerance compared to more traditional MPEMs. The current state-of-the-art modeling and control method, Vector Space Decomposition (VSD), has the drawback of introducing discontinuities in the model when transitioning from one phase-pole configuration to another.

4. 8. Field Oriented Current Control with Harmonic Injection in a Six-Phase Induction Machine

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

   Author : Xinyue Shan; [2021]
   Keywords : Multi-phase machine; asymmetrical six-phase induction machine; harmonic plane decomposition; indirect rotor field oriented control; parameter estimation; Flerfasmaskin; asymmetrisk sexfasinduktionsmaskin; harmonisk plan sönderdelning; indirekt rotorfältorienterad styrning; parameteruppskattning;

   Abstract : As a new type of machine, the multi-phase machine has the advantages ofhigher power rating, higher fault tolerance capability and more degrees offreedom to control compared with the traditional machine. Aiming at runninga multi-phase machine with different phase-pole configurations smoothly,a new method called harmonic plane decomposition is presented. READ MORE

5. 9. Geological characterisation of geophysical lineaments as part of the expanded site descriptive model around the planned repository site for high-level nuclear waste, Forsmark, Sweden

   University essay from Lunds universitet/Geologiska institutionen

   Author : Aron Bakker; [2021]
   Keywords : Forsmark; deformation zones; Svecokarelian; Sveconorwegian; ductile-brittle transition; brittle deformation; mylonite; Earth and Environmental Sciences;

   Abstract : The Swedish Nuclear Fuel and Waste Management Co. (SKB) started a project in 2020 near Forsmark, Sweden with the aim to expand the deformation zone model to encompass the entire catchment area around the planned repository for spent nuclear fuel. READ MORE

6. 10. Attenuation of fan noise with passive methods : An experimental study in the implementation of a ducted fan inside the body of a blended wing body UAV

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Mustafa Kulbay; [2021]
   Keywords : ;

   Abstract : This report is about a novel approach to attenuation of fan noise in aerial vehicles, by way of implementing a ducted fan in the chassis of a four meter blended wing body plane. Three different one meter PVC pipes were used and their performances as silencers were tested by measuring the sound power level and calculating the insulation loss compared to a fan by itself.
