摘要
设计了一种新的基于高可靠无缝冗余协议(HSR)的智能电网网络故障定位方法。该方法对HSR监视帧的可填充字段进行了优化。利用HSR监视帧的发送机制,通过HSR环网中各节点接收到的监视帧,形成该节点上的全网节点连接表。若运行过程中,环网上某段通信光纤或某个节点发生故障,各节点收不到相关的监视帧。根据实时的全网节点连接表的变化,即可知道对应环路发生了故障,从而实现对故障的精确定位。详细介绍了基于HSR监视帧的故障定位设计原理以及典型故障的定位方法。
A new fault location method for the smart grid based on High-availability Seamless Redundancy(HSR)protocol is designed.The transmission mechanism of an HSR_Supervision frame is used and the padding field is optimized.When each node in the HSR network receives the HSR_Supervision frames sent by other nodes,a table named AllNodeConnectTable of this node is formed to reflect the whole network topology.In the process of operation,when a fault occurs on a communication fiber or a node on the HSR ring,other nodes fail to receive the relevant supervision frames.The AllNodeConnectTables are changed,from which the fault location in the corresponding ring is determined accurately.This paper introduces in detail the design principle of fault location based on the HSR_Supervision frame and the location method of typical faults.
