摘要
过程层网络是智能变电站的技术关键点与难点。在满足过程层网络实时控制需求的基础上,结合现有技术条件,分析了过程层网络拓扑结构、采样值传输协议、采样值与GOOSE共网/分网、报文过滤技术选择的合理性,并针对500 kV线-线串典型间隔进行了流量计算,在此基础上,提出了500 kV线-线串网段过程层网络构建方案。
Process-level network is a technical key point and difficulty for smart substation. Based on the requirement of real-time control of process level network and combined with existing technical conditions, this paper analyses the topology of process-level network, the protocol of SMV, the shared net or separate net of SV and GOOSE, as well as the choice of packet filtering. It makes flow calculation for 500 kV line to line typical bay, and proposes a plan for constructing a process-level network at 500 kV line to line bay＇s network segment.
