基于近年来智能变电站试点工作中的网络设计、建设、调试经验,从可靠性、网络性能、经济性、功能要求等关键点出发,分析了总线型、环型、星型等网络型式及站控层网络、过程层GOOSE网络、过程层SV网络各组合方式的优缺点,并给出各模式的适用条件;从网络负载、装置需求等方面归纳出变电站组网的总体原则,并具体分析了35～500kV各电压等级的站内网络负载情况,给出合理的组网方式,展望了未来智能变电站组网模式。
Based on the experience of network design, construction and commissioning in pilot projects of smart substations in recent years, this paper analyzes network types such as bus type, ring type and star type and station control from reliability, network performance, economy and function requirements. Layer networks, GOOSE network in the process layer and SV network in the process layer, and gives the applicable conditions of each mode. The general principles of substation networking are summarized from the aspects of network load and device requirements. ~ 500kV voltage levels of the station network load, given a reasonable way of networking, and prospects of the future intelligent substation networking mode.
