摘要： A system for time synchronization between multiple operating systems is provided, the system includes a Field Programmable Gate Array (FPGA) configured to obtain and maintain absolute time; and multiple operating systems (OS) that obtain the absolute time from the FPGA and perform time synchronization based on the obtained absolute time. According to the embodiments of the present disclosure, the system can solve the high accuracy time synchronization problem in a protection relay device with multiple operating systems.
