Abrégé
(EN)
The invention discloses a synchronization method and device of a wide-area system protection device, a plant station and a topological structure. The method comprises the stepsof enabling a first plant station to send a first data frame to a second plant station, wherein the first data frame at least comprises a serial number p of the first data frame and a sending timestamp Tst [p] of the first data frame; receiving a second data frame sent by a second plant station, recording a receiving time stamp Tsr [q] of a second data frame, the second data frame comprising a serial number q of the second data frame, a sending time stamp Tmt [q] of the second data frame and a receiving time stamp Tmr [p] of the first data frame, and the first data frame and the second data frame being adjacent to each other on a second station; calculating a time phase difference s and a crystal oscillator frequency deviation fp between the first plant station and the second plant station; and adjusting the timeof the first plant station, and adjusting the clock frequency of the first plant station. According to the technical scheme disclosed by the invention, the wide-area time synchronization of the system protection device can be realized under the condition that the physical architecture and channel configuration of the existing system protection device are not changed.
