摘要
IEC 62439-3标准详细描述了并行冗余协议(PRP)和高可用性无缝冗余协议(HSR)。但是这两种冗余功能对上层应用透明,监控系统无法识别单一链路故障。为了解决该问题,实现PRP、HSR冗余网络的良好维护体验,分析了PRP、HSR冗余的实现过程,研究了监测帧的作用原理,构建了一个基于监测帧的冗余网络监视系统,给出了具体的冗余监测原理和流程,总结分析了该系统的优点,为智能变电站的网络冗余监测提供了一种有效的方案。
IEC62439-3 describes parallel redundancy protocol （PRP） and high availability seamless redundancy （HSR） in detail. However, these redundancy protocols are transparent to upper layer, supervision system cannot identify the single link failure. In order to resolve this problem and achieve good maintenance experience of PRP and HSR redundant network, the implementation process of PRP and HSR redundancy is analyzed, the action principle of detecting frame is researched, and a redundancy network supervision system based on detecting frame is built. The specific redundancy detecting principle and implementation method are put forward, and the advantages of this system are summarized and analyzed, which provides an effective solution for the redundancy network supervision of smart substation.
