1. 21. Design of an electric motor (PMSM) & manufacturing lab

   Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

   Författare :Lama Awawda; [2021]
   Nyckelord :Permanent magnet synchronous machine; PMSM; Finite element analysis FEA ; FEMM; Hairpin winding; Motor assembly; Prototype;

   Sammanfattning : The thesis presents deals with the design, analysis, test and control of permanent magnetsynchronous motor(PMSM). An analytical model was carried out based on the d-q frame and the equivalent circuit of PMSM, theanalytical model gives an approximation value of the machine parameters and is carried out byequations from the listed references.

   Nyckelord :Voltage source converter; Synthetic inertia; Fast frequency response; Power system; STATCOM; Energy storage; Power electronics; Syntetisk svängmassa; Frekvensreglering; Elkraftsystem; energilager; kraftelektronik;

   Sammanfattning : Variable renewable energy sources are today increasingly integrated in the power system as a step towards the renewable society. The large-scale introduction of converter-based energy sources brings challenges in terms of reduced damping to the power system due to the reduced number of synchronous generators. LÄS MER

7. 25. Design of a Simulation Startup Model for a Marine Current Turbine

   Kandidat-uppsats, Uppsala universitet/Elektricitetslära

   Författare :Isak Carlénius; Valle Johansson; [2020]
   Nyckelord :;

   Sammanfattning : This project is aimed at developing a simulation model in Simulink for a new startup system controlling the marine current turbine at Uppsala university's research facility in Söderfors. The goal is to design a circuit that is able to switch between feeding power to and extracting power from the synchronous machine in order to control the rotational speed of the turbine. LÄS MER
