| As the construction of Smart Grid developing steadily, a lot of services applied in Smart Grid has appeared, especially in the power distribution network. So Smart Distribution Grid (SDG) has been the significant part of the Smart Grid. With various information communications need to be done in SDG, it is really important to guarantee the supporting function of the SDG in Smart Grid. So researches in Smart Distribution Grid Communication Network (SDGCN) is paramount in both theory and engineering fields. Researches in the multiple-media convergent communication structure serving for the smart power distribution has been done in this paper, aiming to efficiently apply to the request of SDGCN.Firstly, the situation of the current SDGCN and the demand of such service has been analyzed in the paper, mainly focusing on the demand of communication system in SPDN, the services demand of SDGCN and the level-distribution of various services. According to the common power distribution communication service, both the advantages and the disadvantages has been analyzed and the network structure technology type of SDGCN has been discussed and determined.Secondly, with the previous work, a new type of the multiple-media convergent communication network has been proposed. And the specific network structure designing for heterogeneous convergent networks, Ethernet Passive Optical Network (EPON) and the extended Wi-Fi.Finally, the detailed multiple-media convergent communication terminal designing for SPN has been proposed. The hardware consists of terminal function analyzing part, Micro Control Unit (MCU) part, micro control chip interface part and the power source part. The software designing part cover the main flow chart of the terminal software application. The designing of the SDGCN construction discussed in this paper can sufficiently meet the request both from the current and future SDG, and it has a very promising applying field. |
