1. 1. 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

3. 2. Model verification and common mode current analysis of grid connected three phase two level converters

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Simon Lindvall; Richard Haraldsson; [2021]
   Keywords : active filter; EMC; EMI; converter; common mode; differential mode; shunt active filter; parasitic elements; Technology and Engineering;

   Abstract : In this Master’s thesis an in-depth model of a shunt active filter for high frequency analysis is constructed. The purpose is to enable analysis of higher frequency behavior reaching 1MHz. Using the high frequency model, common mode currents can be simulated. READ MORE

4. 3. Test setup for LDMX HCal readout

   University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Joshua Greaves; [2020]
   Keywords : Dark matter; LDMX; dark photon; hadronic calorimeter; photomultiplier tube; Physics and Astronomy;

   Abstract : It is evident from cosmological observations such as the Cosmic Microwave Background, and the motion of galaxies, that the universe consists of approximately 5 times more mass than visible matter can account for. The Light Dark Matter eXperiment (LDMX) will take a unique approach in its hunt for dark matter; it will look for missing momentum signals in electron collisions with a Tungsten target, and will be looking in the sub GeV energy range for evidence of dark matter interactions.

5. 4. High Temperature Co-Electrolysis Model for Sector Coupling : Thermodynamic and Detailed Models of Solid Oxide Electrolysis Cells and Systems

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

   Author : FAISAL SEDEQI; [2020]
   Keywords : ;

   Abstract : The increased development of intermittent renewable energy supplies not only demands robust storage technology, but also alternative means to produce materials in ways to avoid fossil fuel consumption and make use of the increasing electricity supply. Power to gas (PtG) through solid oxide cell (SOC) co-electrolysis reactors provide an attractive manner to overcome both challenges. READ MORE

6. 5. Design of a Test Equipment : Quality Control on Hydraulic Quick Couplings Used in the Excavation Industry

   University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

   Author : Daniel Andersson; Robin Florbrant; [2020]
   Keywords : Industrial design engineering; mechanical engineering; product design; ergonomics; anthropometrics; machine safety; repetitive work; test equipment; hydraulic quick coupling and excavator.; Teknisk design; maskiningenjör; produktdesign; ergonomi; antropometri; maskinsäkerhet; repetativt arbete; testutrustning; hydraulisk snabbkoppling och grävmaskin.;

   Abstract : Construction machines use quick couplers to rapidly change the attached tool. The gear lets the machine operator control the hooking and unhooking of the tool from inside of the cabin. This saves time and makes construction work much easier for the workers. READ MORE
