The objective of this experiment was to build a model of a synchronous machine working as a generator and check its performance under different conditions: 1) operating with a real load, and 2) operating with no load to determine its no-load curve.

The proposed model can be extrapolated to any size machine. In this study a machine with the following characteristics was chosen: a three-phase wye connected alternator of 3000 kVA, 6600 V phase to phase and 50 Hz, an armature resistance of 0.07 Ω and a dispersion reactance of 0.7 Ω / phase.
