Application of Communication Network Technology in New Generation Smart Substation

As one of the most important parts of smart grid, smart substation is the key node of information interaction of six links in smart grid as well. The substation information network, the trunk communication network between smart substation and the terminal of regulation, operation and maintenance, as well as the terminal communication network between smart substation and power distribution and consumption were systematically studied. Then, the simplified technology route of substation information structure and the development scheme of the trunk and terminal communication network framework were presented. The research results can provide important theoretical supports and practical basis for the research and development of the new generation smart substation, and also provide important guidance for the design and construction of demonstration projects in the next step.
