This can lead to unstable parallel operation because the generators will try to take over from each other, causing the output voltage to fluctuate wildly.<\/p>\n<p>Unequal number of turns in their series field windings, unequal speed regulation of their primemovers, and unequal series field resistances can all contribute to unstable parallel operation, but they are not the main factors.<\/p>\n<p>Unequal number of turns in their series field windings can cause the generators to have different output voltages, which can lead to instability.
