Next generation SCADA time sync architecture using IEEE 1588 PTP protocol
초록
영어
The conventional process to implement time synchronization for SCADA system operation has been as following. GPS receivers are installed in all related sites to maintain time synchronization through NTP and IRIG-B. For RTU peripheral equipments, time synchronization is maintained through time synchronization function inside DNP frame and other TOD (Time of Day) functions. The introduction of Substation Automation System (SA) with IT system and communication infrastructures are accelerating year by year. In addition, a shift is being made to the digital-based(i.e program based) automatic power monitoring and control system with IEC 61850 as a standard. This paper is aimed at introducing plans to implement more precise time synchronization in SCADA system operated with the accurate time synchronization technologies of IEEE 1588, which is drawing attention amid technological advancements in the present times
