计及流量分析的三网合一背景下变电站过程层交换机优化配置

Optimal Configuration of Substation Process Layer Switches in the Context of Three Networks in One Considering Traffic Analysis

通过对变电站过程层报文进行流量分析计算,提出了过程层SV、GOOSE、IEC 61588网络报文"三网合一"的传输模式,重构了自动化系统过程层网络结构,提高了自动化网络利用率。以某220 kV变电站建设为例,优化配置过程层交换机,经过优化计算,该站远景可节省220 kV间隔交换机10台、主变间隔交换机6台、110 kV间隔交换机14台,技术经济优势明显。

By analyzing and calculating the flow of process layer message in substation, the transmission ＂three networks in one＂ mode of process layer SV, GOOSE and IEC 61588 network messages is put forward. The process layer network structure of automation system is reconstructed, and the utilization ratio of automation network is improved. With the construction of a 220 kV substation as an example, the configuration of process layer switch is optimized. After the optimization calculation, the station can reduce 10 sets 220 kV spacer switches, 6 sets main transformer interval switches and 14 sets 110 kV spacer switches, and the technical and economic advantages are obvious.
