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

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

   Sammanfattning : 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).

3. 2. Small Signal Stability of Power Systems With Increased Converter Based Power Production

   Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Gustav Kjellson; Josefin Gustafsson; [2022]
   Nyckelord :Small signal stability; Power system stabilizer; Renewable energy; Grid following converters; Grid forming converters;

   Sammanfattning : The aim of this project is to analyze how increasing the share of converter-based power production in a power system affects the small signal stability. The project also aims to stabilize systems using Power System Stabilizers (PSSs), and examine the effect of two different types of power electronic converters: grid following (GFL) and grid forming (GFM).

4. 3. Comparison of control strategies for Peltonturbines in Wave Energy Converters

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :PHILIP HAMILTON; ANDREAS SJÖGREN; [2021]
   Nyckelord :Permanent Magnet Synchronous Generator; Synchronous Motor; Wave Energy Converter; Pelton Turbine; Velocity Control Strategies; Dead-time Strategies; Cascaded Control; Permanentmagnetgenerator; Synkrongenerator; Synkronmotor; Vågenergiomvandlare; Peltonturbin; Hastighetskontrollstrategier; Mellantidsstrategier; Kaskadreglering;

   Sammanfattning : Wave energy is a promising renewable resource with a higher energy density than both wind and solar. Waves can travel thousands of kilometers with minimal energy loss, making them more reliable than the previously mentioned alternatives. A device that utilizes wave energy to generate electricity is calleda Wave Energy Converter. LÄS MER

5. 4. Pre-study and system design of a mobile platform simulator system

   M1-uppsats, KTH/Hälsoinformatik och logistik

   Författare :Luis Katewa; [2018]
   Nyckelord :Automatic voltage regulator; control systems; synchronous generator; gas turbines; PID control; simulator; Automatisk spänningsregulator; styrsystem; synkrongenerator; gasturbiner; PID-kontroll; simulator;

   Sammanfattning : There are many ways to produce energy, using e.g. gas or hydro turbines. To guarantee a stable power output, it is important to consider components that could control and adjust the output power automatically. LÄS MER

7. 5. Construction, testing and verification of a brushless excitation system with wireless control of the field current in a synchronous generator.

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

   Författare :Rickard Larsson; Kenny Andersson; [2018]
   Nyckelord :Brushless excitation; synchronous generator; bluetooth; torque ripple; Borstlös matning; synkrongenerator; blåtand; momentpulsationer;

   Sammanfattning : Synchronous generators have been used in hydropower from more than a century where, traditionally, the field current is transferred to the rotor using slip rings and carbon brushes. There are some major disadvantages following the use static excitation; regular and expensive maintenance, as well as a source of carbon dust which, due to buildup, may cause short circuits. LÄS MER
