IEC 61850通信冗余实施方案

由于IEC 61850没有对通信冗余的实现加以具体的规定,目前已经提出了几种不同的通信冗余实现方案.IEC 61850的理想方案是在智能电子设备(IED)的逻辑访问点的地址层下实现通信冗余,即IED单一IP地址实现通信冗余.但是目前提出的单一IP地址实现方案,无论是在协议栈附加特定通信服务映射(SCSM)参数方案,还是基于以太网交换机的单环网方案,都存在不能完全互操作的问题.双星形独立子网是文中重点讨论的另外一种通信冗余实现方案.虽然该方案也存在互操作问题,但是该方案具有更高的可靠性,可用于保护功能相关的双重化通信,并能与以往的IEC 60870-5-104通信冗余实现保持一致.文中推荐在将来的IEC 61850通信冗余实现上使用这种方案,并建议在将来的IEC 61850版本中对具体通信及通信冗余的实现进行更详尽的描述,以满足在通信冗余下IED之间互操作性的要求.
