智能电网是国内外电网技术发展的必然趋势,已成为各国电网技术研究的重要内容,而智能配电网络的建设是关键环节。从我国智能配电网的现状及需求来看,目前主要问题在于通信接入层部分的网络建设。介绍了利用未来无线通信技术分时长期演进(TD-LTE,Time Division Long Term Evolution)网络技术建设智能配电网络及使用无线通信建设智能电网的关键技术,分析了TD-LTE Smart grid is the inevitable trend of the development of power grid technology at home and abroad, and has become an important part of the national grid technology research, and the construction of smart power distribution network is the key link. Judging from the status quo and demand of China’s smart distribution network, the main problem now lies in the network construction of the access layer of the communications. This paper introduces the key technologies of building smart distribution network by using the TD-LTE (Time Division Long Term Evolution) network technology and building a smart grid using wireless communication, and analyzes the key technologies of TD-LTE
