| Electric power communication is the basis to ensure the power grid security,stability and economic operation, along with the continuous expansion of the power grid,power communication business transition to larger particles of IP business, the originalTDM pipe and fixed particles based on SDH network in the business processing,bandwidth efficiency, the scalability of the network cannot meet the needs.PTN technology is the integration of circuit-switched and packet-switched networksthe advantages of both sides and developed a kind of packet switching technology,conform to the trend of business IP and network integration, it has high efficiency of thestatistical time division multiplexing, many business carrying, hierarchical QoS (qualityof service) characteristics in many aspects. This paper expounds the connotation of PTNtechnology, layered structure, classification, function plane, and the key technology ofnetwork elements in the electric power communication and the application of the smartgrid has carried on the detailed demand analysis, system, discusses its application inelectric power communication architecture.Based on the PTN technology and its application in smart grid in detail, by JingxianCounty electric power PTN transmission network construction as an example, introducesin detail the county power company business data type, mode of transmission,application scenarios, in-depth analysis of the transmission network problems, proposedthe development of PTN network, the construction of soft switching business, designscheme using protocol conversion equipment. By combining the PTN network,SDH/MSTP network and IP network respectively, plane and design the networkarchitecture and service configuration of Jingxian County PTN. Delve into PTNequipment in county electric power communication transmission network and thefeasibility of the application in the smart grid, technical solutions and Futuredevelopment. |
