Title:
MULTI-MACHINE PHASE SYNCHRONIZATION SYSTEM AND METHOD BASED ON OPTICAL FIBER TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2024/007439
Kind Code:
A1
Abstract:
Disclosed in the present invention are a multi-machine phase synchronization system and method based on optical fiber transmission. The system comprises a master device and a plurality of slave devices; an optical fiber transmission interface of the master device is connected to an optical fiber reception interface of one slave device, and the slave device connected to the master device is sequentially connected to other slave devices in series; the master device transmits phase information of a digital reference source of the present device as a system synchronization phase signal to the slave device connected to the master device; the slave device takes the received system synchronization phase signal as a digital reference source phase of the present device, and sends, by means of an optical fiber transmission interface, the system synchronization phase signal to a slave device connected to the optical fiber transmission interface of the slave device; and when the last slave device is connected to the master device, the master device and the slave devices form a closed-loop communication test. According to the present invention, a synchronous phase code value is transmitted in real time in high-rate optical fiber communication, the accuracy is high, a phase change can be tracked in real time, and good synchronization performance and expansibility are achieved in a multi-machine power system.
