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。
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.
