Abstract

디지탈 종합 보호 계전 시스템용 통신망에 관한 것으로, 본 발명에 따른 통신망은 변전소의 보호 제어를 위한 충분한 기능을 제공하면서 망요구조건을 완화하고 좋은 확장성을 갖을 수 있도록 2레벨의 계층구조를 갖는다.The present invention relates to a communication network for a digital integrated protective relay system. The communication network according to the present invention has a two-level hierarchical structure so as to reduce network requirements and have good scalability while providing sufficient functions for protection control of a substation.

제1레벨은 스타형 구조로 이루어져 시스템의 감시 및 제어용 데이터를 취급하며, 제2레벨은 일대일 접속으로 이루어져 모선보호에 쓰이는 실시간 데이터를 취급한다.The first level consists of a star structure and handles data for monitoring and control of the system, while the second level has one-to-one connection and handles real-time data used for bus protection.
