| 摘 要： | 智能变电站自动化系统大量应用双星形以太网实现网络冗余，目前国内在网络冗余上普遍采用双网双地址机制，而IEC／TR61850—90—4推荐采用PRP协议机制。文章研究了PRP协议原理、实现方式、IEEE1588的支持方式，以及在应用层实现网络冗余的方法和建模方式，并分析了2种机制各自的特点，提出了智能变电站的网络冗余方式建议。

| Abstract: | Dual star Ethernet networks has been widely used to realize network redundancy in smart substation automation systems （SSAS） based on TEC61850. Currently the scheme of dual net dual IP address has been generally used in SSASs in China. IEC/TR61850-90-4 suggests using parallel redundancy protocol （PRP）.The paper studies the principle and realization way of PRP and its supporting scheme of IEEE 1588. Meanwhile the redundant scheme in application layer and its modeling method are also studied. After analyzing the features of two redundant schemes, this paper gives a network redundancy solution for smart substation. |
