1. 1. Electromagnetic compatibility of unmanned aircraft : Examination of legislation and evaluation of two commercial systems

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Alex Bergdahl; [2022]
   Keywords : Electromagnetic compatibility; Unmanned aircraft; Electromagnetic compatibility legislation;

   Abstract : Electromagnetic compatibility (EMC), or the field of reducing emissions from and increasing immunity against electromagnetic interference, is an essential part of designing modern electronics. As one would expect, EMC is especially important for things such as aircraft and aviation equipment where outages or disturbances could have severe consequences. READ MORE

3. 2. 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).

4. 3. Mitigating SSCI in a hybrid wind and PV farm utilizing PV-STATCOM : A Swedish case study

   University essay from Högskolan Dalarna/Institutionen för information och teknik

   Author : Isabelle Löfgren; [2022]
   Keywords : impedance analysis; PV-STATCOM; SSCI; SSO; SSR; sub-synchronous control interaction;

   Abstract : The share of electricity generation in the power system being based on power electronics is increasing, which will impact the system in different ways, such as an increased risk for undesired interactions. An example is doubly fed induction generator (DFIG) based windfarms which have been shown to present negative resistance in (parts of) the sub-synchronous range (i. READ MORE

5. 4. Investigations of the Transient Luminous Events with the small satellites, balloons and ground-based instruments

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Safura Mirzayeva; [2022]
   Keywords : TLE; sprite; jet; elve; halo; lightning; lighting detection; upper-atmospheric lightning; lightning location; nanosatellite; CubeSat;

   Abstract : The lightning is the natural source of electromagnetic radiation. It is an atmospheric electrical discharge.  However, since recent times, it was discovered that there are other types of lightning besides those that are visible to the naked eye. They are called TLEs (Transient Luminous Event) and take place above the clouds during thunderstorms. READ MORE

6. 5. Evaluation of DC Fault Current in Grid Connected Converters in HVDC Stations

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Soham SinhaRoy; [2022]
   Keywords : Symmetrical monopole; HVDC LCC and VSC; CTL; MMC; Converter reactor; DC smoothing reactor; DC pole-to-pole fault; Peak factor; SCC; SCR; PSCAD EMTDC;

   Abstract : The main circuit equipment in an HVDC station must be rated for continuous operation as well as for stresses during ground faults and other short circuits. The component impedances are thus selected for proper operation during both continuous operation and short circuit events. READ MORE
