摘要：

摘要：在新一代智能变电站建设中，为保证中低压母线的可靠性和安全性，充分利用先进的网络通信技术提供的可共享的数据信息，与合并单元和智能单元配合，提出了适用于智能变电站的环网分布式弧光保护系统。通过双重冗余环网将从机互联并共享数据，依托于通信的高可靠性，各从机不进行逻辑判断，采用单主机设计方案。点带通用式传感器及其自检技术有利于系统的扩展和检修，快速跳闸技术可提高智能变电站的整体性能。

Abstract:

Abstract:In the new generation intelligent substations, to protection the LV busbar, shared information provided by advanced internet communication technology was fully applied, incorporate with merging unit and intelligent unit, ring grid distributed arc protection for intelligent substation were indicated. Slaves interconnected by dual redundant ring grid and share data with each other. Based on highly reliable communication, logical judgement will not be done by salves. Pointband universal type sensor and its selfinspection technology will benefit the system extension and maintenance. High speed tripping technology will increase the overall performance of intelligent substation.
