Reliability Analysis Model for Intelligent Substation Information Flow

摘要:

智能变电站是智能电网可靠运行的关键环节和重要基础,为避免变电站可靠性的单一定性评估方法给变电站状态监测、检修决策带来的不足,在分析智能变电站及其信息流特征的基础上,从不同角度归纳了智能变电站网络可靠性的评估方法；给出一种基于信息流传输时延、丢包率和各信息流QoS要求的信息流可靠性评估模型,并通过在稳态和极限流量运行方式下对该模型进行了仿真实验,结果表明该方法能在一定程度上定量评估智能变电站信息流的可靠性问题。

Abstract:

Intelligent substation is the key and important basis for reliable operation of the smart grid, based on analyzing the characteristics of intelligent substation and information flow, from different angles summarizes the assessment of intelligent substation network reliability, then an evaluation approach of intelligent substation information flow is presented based on its transmission delay, packet loss rate and QoS. And emulation under the steady-state and limit traffic mode, the results show this method can be used to evaluate the reliability of the information flow in the substation to a certain degree.
