1. 6. Ride through Capability of medium-sized Gas Turbine Generators : Modelling and Simulation of Low Voltage Ride through Capability of Siemens Energy's medium-sized GTG and Low Voltage Ride through Grid Codes requirements at point of connection

   University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Author : Daniel Almailea; [2023]
   Keywords : Gas Turbines; Synchronous Machines; Generators; Turbogenerators; Fault Ride Through FRT ; Low Voltage Ride Through LVRT ; Grid Codes; Frequency; Inertia; Generator Inertia; Power System; MATLAB; Simulink; Modeling; Excitation System; Automatic Voltage Regulator AVR ; Saturation Curve; Capability Curve; Load Angle; Siemens Energy.;

   Abstract : In order to reduce emissions and achieve sustainable energy systems, renewable energy is increasingly being integrated into the power grid. However, the integration of renewable energy into the grid poses several challenges, including maintaining a stable power supply under changing and unpredictable conditions. READ MORE

3. 7. Software Defined VNA : Measure Coupling Between Elements in an Antenna Array

   University essay from Uppsala universitet/Signaler och system

   Author : Alexander Söderlund; [2023]
   Keywords : VNA; Vector Network Analyser; SDR; KrakenSDR; S-parameter; Antenna Coupling;

   Abstract : With improvements in hardware of antenna receivers, fully digital arrays have been made possible to use in real time systems. These systems have a greater complexity, with the advantage of more dynamic system design since the use of the communication system can be changed with only a software change. READ MORE

4. 8. Exploring true random number generators Build on commercial-off-the-shelve Components

   University essay from Malmö universitet/Institutionen för datavetenskap och medieteknik (DVMT)

   Author : Linnéa Mörk; [2023]
   Keywords : TRNG; RNG; Random number generator; commercial-off-the-shelve;

   Abstract : Generating random numbers can be accomplished through various methods, with the primary distinction lying between pseudo-random number generators (PRNGs), which are commonly used for applications that require a large amount of random data, and true random number generators (TRNGs), which are commonly used for applications that need security and unpredictability. This thesis explores the feasibility of harnessing frequency variations in the electrical grid as a source of entropy for a TRNG. READ MORE

5. 9. Forced response numerical investigation of a transonic compressor rotor

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

   Author : Mariana Pires Gonçalves Toco Dias; [2023]
   Keywords : Compressor; rotor; blisk; aeroelasticity; aerodynamic damping; CFD; transient; forced response;

   Abstract : The present thesis discusses the forced response of a rotor’s bladed-disk when excited by the periodic force produced by a wake generator, or Inlet Guide Vane (IGV),with 8 equally-spaced blades. These components are part of an axial transonic compressor rig, moreover the Transonic Compressor Darmstadt 1 (TCD1), located at the Technical University of Darmstadt. READ MORE

6. 10. Application of harmonic injection method to analyse Sub-Synchronous Control Interactions (SSCI)

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

   Author : Linus Eriksson; [2022]
   Keywords : Sub-synchronous control interaction SSCI ; damping of SSCI; DFIG; PSCAD; Power Oscillation Damper POD ; Harmonic Injection; Subsynkrona kontrollinteraktioner SSCI ; dämpning av SSCI; DFIG; PSCAD; Dämptillsats POD ; Harmonisk Injection;

   Abstract : Wind farms are commonly connected to the main grid through compensated lines which increases the power transfer capability of the line. Double Fed Induction Generator (DFIG) wind turbines in connection to compensated lines can experience Sub-Synchronous Control Interaction (SSCI) which can bring system quantities above allowed levels.
