Abstract
Provided are a synchronization method, a wide area system protection apparatus, a plant station and a computer readable storage medium. The method includes: sending to a second plant station a first data frame that includes a sequence number p and a sending timestamp of the first data frame; receiving a second data frame sent by the second plant station, and recording a receiving timestamp of the second data frame, the second data frame including a sequence number q of the second data frame, a sending timestamp of the second data frame and a receiving timestamp of the first data frame, and the first data frame being adjacent to the second frame on the second plant station; calculating a time phase difference and a crystal oscillator frequency deviation between the first plant station and the second plant station; and adjusting time and a clock frequency of the first plant station.
