RETURN HOMESynchronous machine complex power
The animation examines the complex power delivered by a synchronous machine as
the torque angle δ varies from -180° to 180° while maintaining the excitation
voltage E fixed at controlled levels. The per-unit machine parameters , namely
Vt, Xd, and Xq, can be adjusted independently. The characteristics are shown in
the form of PQ plots in the complex plane; they have the shape of
'limaçon' of Pascal which reduce to concentric circles in the absence of
saliency. Also shown are plots of the active and reactive powers as functions of
angle. |
