  3. 7. High-Frequency Voltage Distribution Modelling of a Slotless PMSM from a Machine Design Perspective

    University essay from KTH/Elkraftteknik

    Author : Patrik Brauer; [2018]
    Keywords : Windings; drives; transients; surges; steep-fronted; slotless; litz-wire; effective relative permeability; Lindningar; elektriska drivlinor; transienter; spänningspulser; litz-tråd; effektiv relativ permeabilitet;

    Abstract : The introduction of inverters utilizing wide band-gap semiconductors allow for higher switching frequency and improved machine drive energy efficiency. However, inverter switching results in fast voltage surges which cause overvoltage at the stator terminals and uneven voltage distribution in the stator winding. READ MORE

  4. 8. Calculating the Risk of Power Shortage in the Nordic Power System

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

    Author : Alessandro Crosara; [2018]
    Keywords : ;

    Abstract : In the near future, the decommissioning of large power plants is planned in the Nordicelectric power system, due to environmental and market reasons. This will be counteredby an increase in the wind power installed capacity, as well as by signicant investmentsin the transmission system. READ MORE
