20130168960 | METHOD AND APPARATUS FOR POLE-SLIP DETECTION IN SYNCHRONOUS GENERATORS - A system and method for predicting a pole slip in a synchronous generator is provided. The system includes a stator voltage frequency detector to determine the frequency of the stator voltage, a mechanical frequency detector to determine the rotational speed of the rotor and a prediction unit that is operative to disconnect the generator from a power grid if it determines that that a pole slip is likely based on comparison of the frequency of the stator voltage and the rotational speed of the rotor. | 07-04-2013 |
