The method includes: collecting, by a control device, current on an outlet side of a generator in 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.
