Abstract:

Electric power communication access network is an important part of power communication network which provides comprehensive support for smart grid. With the development of smart grid, the urgent need is to enhance the level of intelligent network operation and maintenance through technical means to reduce operation and maintenance costs. Meanwhile, the "Internet plus", "Cloud" and other new technologies have been promoted the application. Electric power communication network is undergoing significant change. The increasing of all levels on electric network and user data acquisition, the rising demand for mobile services, construction of distribution network will be the focus. By studying the technical characteristics of power long term evolution (LTE) wireless technology and its application in areas of access network, the paper proposed overall network architecture of power LTE wireless network, and studied LTE wireless communication channel parameters. Finally, through testing and analyzing performance of on-site power LTE communication network which combined currently deployed system, this study can provide technical support for unified construction and unified management of the power terminal access network. The study and the result will lay a solid foundation for the promotion and application of power private LTE network.
