中文摘要:当前智能变电站过程层网络存在流量大、延时大等问题,但该问题并没有从理论上进行分析研究。文章从过程层网络GOOSE、SV的报文特征和组网情况出发,采用严格的以太网延时排队方法对不同组网情况下的网络传输延时和设备缓存需求进行了理论研究。基于分析得到了严苛情况下的网络延时值和网络设备的缓存需求,同时基于研究结果给出了推荐的过程层组网建议。为智能变电站过程层组网提供了理论分析的基础和依据。

Smart Substation Process Layer Network Optimization and Flow Analysis
Abstract:At present, the process layer network of smart substations has the problems of large flow and large delay, but this problem has not been theoretically analyzed. Based on the characteristics of GOOSE, SV and process layer networks, A kind of strict ethernet delay queuing method is used to theoretically study the network transmission delay and device cache requirements in different networking situations. Based on the analysis, the network delay value and the network device's cache requirements under severe conditions are obtained. At the same time, the recommended process layer networking is given based on the research results. The basis for theoretical analysis is provided for the process layer networking of smart substations.
