Abstract


This paper presents a method for determining internal generated voltages induced in a salient pole synchronous generator in the 3-phase armature winding, both with and without a rotor skew in the no-load steady state. The induced phase stator voltages are determined using a linear model in the natural reference frame of the stator and rotor without considering damping circuits during supplying field winding from DC voltage or DC current source. In the circuital model, the stator to field mutual inductances and the field winding self-inductance are determined in the FEMM program. Simulations made in the circuital model and in the program Flux 2D Skew of the waveforms of the induced phase stator voltages during supplying field winding from DC voltage, are verified experimentally in a laboratory stand
