  1. 1. Resonant overvoltages caused by transformer energization and saturation : Two EMT case studies conducted using models of the grid in Stockholm and an off-shore wind farm

    University essay from Uppsala universitet/Elektricitetslära

    Author : Gustav Sundberg; [2021]
    Keywords : Resonant overvoltages; Resonance frequency; Parallel resonance; EMT studies; Transformer saturation; Off-shore wind power; Inrush current; Sympathetic Inrush; Resonanta överspänningar; Resonansfrekvens; Parallellresonans; EMT-studier; Magnetiseringsström; Havsbaserad vindkraft;

    Abstract : This thesis investigates the impact of resonant overvoltages and their origin. Series and parallel resonances are present in any electrical grid. The frequency of which this resonance occurs is called resonance frequency. READ MORE

  3. 2. Detection of stator interturn fault of synchronous machine by rotor current analysis : A SIMULATION APPROACH

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Ata-E Rabbi; [2016]
    Keywords : Synchronous machine; interturn fault; stator fault; rotor current; harmonic current; generator protection; motor protection; inductance matrix.; synkronmaskin; varvfel; statorström; rotorström; strömöverton;

    Abstract : One of the major electrical faults of synchronous machines is an interturn short circuit in the stator winding, due to winding insulation failure. A synchronous machine is designed to have electrical and mechanical symmetry in the stator and rotor. READ MORE
