Abstract :
IN most studies of power system disturbances made on the a-c network analyzer, the transient rotor saliency of the synchronous machines is neglected. The validity of this assumption is well established. However, in some cases it has been desirable to measure the variations in several of the bus voltages during the disturbance. When the bus is electrically near to a synchronous machine (in the limit, when the voltage in question is at the terminals of one of the synchronous machines), the validity of neglecting saliency may be questioned.
