APPARATUS AND METHOD FOR SYNCHRONIZATION USING TIME ERROR RATE IN PROCESS LEVEL OF FULL DIGITAL SUBSTATION AUTOMATION SYSTEM

摘要

Provided are an apparatus for synchronizing a start at a process level of a full digital substation automation system by using a start time error rate, in which an operation period of a start synchronizing processor is set according to a measured time error rate, and a method thereof. An apparatus for synchronizing a start at a process level of a full digital substation automation system by using a start time error rate comprises a calculating unit for calculating a time error of a current period based on reference time information and self-time information and calculating a time error rate based on a time error calculated for a previous period and the time error calculated for the current period; a determining unit which determines whether a time error occurs based on the time error calculated for the current period by the calculating unit; and a setting unit for setting an operation period of a time synchronizing processor based on the time error rate calculated by the calculating unit and an operation period setting curve when the determining unit determines that the time error has occurred.
