智能变电站网络设计研究

Research on Network Design of Smart Substation

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。

This paper summarizes the experience of network design, construction and debugging experiences in smart substation. Combining with several key problems such as reliability, capability, economy and function, it analyzes the ad- vantages and disadvantages of the bus, ring and star networks as well as the combination mode of the station level net work, process level GOOSE network and process SV network, and the application conditions of these models are enumer- ated. The general principles of network design are concluded in the aspects of network load and functional requirements, and the reasonable network for each voltage grade is presented based on the network load. Finally, the future network de sign of smart substation is presented by combining with the development of smart devices.
