基于光纤+SDH+IP技术的继电保护及故障信息传输系统

继电保护及故障信息传输系统是一个分布式管理系统。通过分析信息传输和信息流向，提出单子站和多主站的概念。结合电力系统数据网络现状，构建了一个基于光纤 SDH IP技术体制的网络化继电保护信息传输系统方案，并介绍了一个220kV变电所继电保护信息子站系统的结构和信息传输的技术方案及其设计经验。

RELAY PROTECTION AND FAULT INFORMATION TRANSFER SYSTEM BASED ON OPTICAL FIBER + SDH + IP TECHNOLOGY

Relay protection and fault information transfer system is a distributed management system. After analyzing the information transfer system requirements and information flow direction, the concept of single local station to multi host station is introduced. Combining data network technology architecture with power systems, ideas of making up a network information transfer system are set up and then the relay protection and fault information transfer system based on optical fiber SDH IP technology architecture is built up. For instance, a practical project is described, including local station frame, technology scheme of information transfer system, equipment selection and design experience.
