Abstract: Systems and apparatuses include an alternator including a stator and a rotor structured to be coupled to a crankshaft of a prime mover, and processing circuits structured to: determine a crankshaft position, associate a crankshaft timestamp with the crankshaft position, determine a stator voltage waveform position, associate a stator voltage waveform timestamp with the stator voltage waveform position, determine a common time base using the crankshaft timestamp and the stator voltage waveform timestamp, determine a rotor position based on the crankshaft position and associated with the common time base, determine a load angle based on the rotor position and the stator voltage waveform position using the common time base, compare the load angle to a stability limit, and transmit a predicted pole slip signal to at least one of the prime mover or the alternator to inhibit a pole slip event when the load angle exceeds the stability limit.
