  • Symmetrical and unsymmetrical voltage sag effects on the three-phase synchronous machine stability 

    Aguilar Galván, Daniel; Rolán Blanco, Alejandro; Vázquez, Gerardo; Córcoles López, Felipe; Rodríguez Cortés, Pedro (2009)
    Conference lecture
    Open Access
    This paper focuses on the effects of voltage sags, both symmetrical and unsymmetrical, on the three-phase Synchronous Machine (SM). Voltage sags on SM cause speed variations, current and torque peaks and hence may cause ...
