Abstract
The disclosure discloses a generator circuit breaker control method based on short-circuit fault current symmetry. The method includes: collecting, by a control device, current on an outlet side of a generator 7 real time; calculating a transferring current feeding moment based on a current symmetry method when fault current rises to a peak value after a short-circuit fault occurs; correcting the transferring current feeding moment by a correction coefficient; and then calculating a breaker switching moment, thereby realizing precise control on a generator circuit breaker. The method mainly addresses the situation that the existing control method cannot effectively cope with the complexity of the short-circuit fault current on the outlet side of the generator, and fills the blank of the effective method for short-circuit control of the generator circuit breaker.
