| 摘 要： | 针对设备自动化实时用以太网(EPA)标准在智能变电站系统应用时的网络冗余问题,分析了分布式冗余协议(DRP)的通信机理及故障检测和恢复机制。研究并设计了应用于处理智能变电站系统中链路故障恢复的环网模块。在实际智能变电站系统中,通过测试验证表明,与基于环网的媒体冗余协议(MRP)和并行冗余协议(PRP)的冗余方案相比,以DRP为基础设计的环网模块更能保证环网链路故障后的自愈修复,且满足基于EPA的智能变电站的自愈时间要求。

| Abstract: | Faced with the network redundant problem when real-time ethernet for plant automation(EPA) standard is applied to smart substation,communication mechanism,failure detection and recovery mechanism of distributed redundancy protocol(DRP) are analyzed.Ring network module is studied and designed for treating link failure recovery of smart substation system.Making a comparison between media redundancy protocol(MRP) and parallel redundancy protocol(PRP),the test results show that the designed ring network module based on DRP can achieve less self-healing time when link failure happens,and the requirements of link failure recovery time limit in smart substation based on real-time EPA are met. |

| Keywords: | smart substation real-time ethernet redundancy technology ring network module self-healing recovery |
