Research On Communication Technology Of Smart Distribution And Utilization Network

21st century is facing a shortage of traditional energy and grave situation of environmental degradation, assure energy security and respond climate change become the two core objectives of a major national's energy strategy. Because Smart Grid is an effective way of solve the climate and energy problem, so it become the inevitable trend of the international network development.At present, smart grid construction is carry out overall in China, with the continuous development of smart grid technologies,it's application system of Distribution and Utilization is gradually improving. Smart Grid request the communication network's bandwidth and reliability higher. The Distribution and Utilization communication network is an important part of the electric power communication network, Is extension of the power trunk communication network, however, because of its wide coverage, node more,construction difficult and other reasons, has been lack of appropriate mode of communication technology and construction,it become the bottleneck of the development of electric power communication network, restricted the application and conduct of the smart Distribution and Utilization business.This paper makes a deep analyze on the characteristics and and business development needs of smart Distribution and Utilization network, from the technical, economic analysis and comparison some suitable communication technologies,such as PON,WiMAX,PLC Etc.Finally it presents the system Architecture and network scheme of the smart Distribution and Utilization communication network.
