Abstract

This paper proposes precise time synchronization-based synchronized sampling structure applied HW/SW platform for LAN-based protection of future digital substations. The integrated software of the proposed platform includes IEC 61850 protocol, IEEE 1588 precision time protocol and synchronized sampling structure. The proposed platform expected to provide a basis of an application of future distributed sensing data-based protection and control methods by providing synchronized measurement among IEDs. The implementation of the proposed HW/SW platform technique was performed using TMDXIDK572 multi-core/multi-processor evaluation module and its time synchronization performance and synchronized sampling function were confirmed through the performance tests.

본 논문에서는 미래 LAN 기반 디지털 변전소 보호를 위하여 정밀 시각동기 기반 동기 샘플링 구조를 적용한 계통 구성 IED(Intelligent Electronic Device)의 HW/SW 플랫폼을 제안하였다. 제안한 플랫폼은 전력계통 자동화를 위한 표준인 IEC 61850 프로토콜 및 IED 간 정밀 시각동기를 위한 IEEE 1588 Precision time protocol 통합 소프트웨어가 적용되었으며, Synchronized reference signal을 이용한 IED 간 동기 샘플링 구조를 적용하였다. 이는 미래 IEC 61850 기반 디지털 변전소에 적용될 네트워크 기반 데이터 송수신 환경에서 IED 간 동기 측정된 계전 데이터를 제공하게 함으로써, 네트워크 기반 분산 측정 데이터를 이용한 새로운 보호 및 제어방식을 적용할 수 있는 토대를 제공할 것으로 기대된다. 제시한 플랫폼 기술의 타당성 및 성능을 측정하기 위하여 TMDXIDK572 멀티코어/멀티프로세서 EVM(Evaluation Module)을 기반으로 구현하였으며, 성능 시험 환경을 구성하여 제시한 플랫폼의 시각동기 성능 및 동기 샘플링 기능의 동작을 확인하였다.
