Power generation with brushless doubly fed induction generator

Variable speed constant frequency power generation with doubly fed induction generator

Phasor Diagram DefinedA phasor diagram is a graphical representation of the phase relationships between different electrical quantities in an AC circuit, specifically used here for synchronous generators.Drawing BasicsEf which denotes excitation voltageVt which denotes terminal voltageIa which denotes the armature currentθ which denotes the phase angle between Vt and Iaᴪ which denotes the angle between the Ef and Iaδ which denotes the angle between the Ef and Vtra which denotes the armature per
