  1. 1. Fault diagnosis of a variable pole-phase motor

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

    Author : Claes Henriksson; [2023]
    Keywords : Multiphase machine; variable pole-phase machine; fault diagnosis; switch fault; phase fault; harmonic plane decomposition; wound independently controlled stator coil machine; Multifasmaskin; variabel polfasmaskin; feldiagnosticering; brytarfel; fasfel; harmonic plane decomposition; WICSC-maskin;

    Abstract : Wound Independently Controlled Stator Coil (WICSC) machines are a novel type of multiphase machine with the ability to change its pole-phase configuration during operation. This enables improved post-fault control and thus prolonged continuous operation. READ MORE

  3. 2. Line Distance Protection in Power Grids with Variable Renewable Energy Sources : An Investigation on Time Domain Distance Protection via Parameter Estimation

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