Reliability Analysis and Optimization Strategy for Smart Substation SAS Communication Network

为优化智能变电站自动化系统的可靠性,遵循通信网络系统可靠性分析的基本思路,采用可靠性框图分析方法分析计算了影响自动化系统网络可靠性的关键因素,并着重从网络拓扑结构选型、系统的冗余配置方案、网络的管理与维护等方面,提出自动化系统网络可靠性优化策略,以指导和优化系统设计。

In order to optimize automation system network reliability,according to communication network system reliability analysis theory,the reliability block diagram analysis method is applied to calculate the reliability indices for the typical network system.The quantitative analysis is used to illustrate the key influencing factors on reliabilities of smart substation.From the aspects of network topology structure,the redundancy of system configuration,network management and maintenance etc,this article puts forward automation system network reliability optimization strategy for guiding and optimizing the system design.
