Developing a power wireless private network based on TD-LTE technology for intelligent distribution networks

摘要

With the development of smart grid, the requirements of high speed, low delay and better coverage have motivated the need to a power wireless broadband private network that bridge the communication gap between the transmission network systems and the customers. In this paper, we give a general overview of studies on the major parameters in the distribution network communication system, and propose a new electric power wireless communication network of TD-LTE230 as well. The TD-LTE230 system is designed based on TD-LTE, and rebuilds its physical layer at 230MHz. the traditional spectrum for electric power system. A TD-LTE230 system has been deployed at Haiyan, Zhejiang province. After a year of stable operation, it has proved that as a good communication resolve scheme, TD-LTE230 system resolves the problems of wide coverage and too many measured points in the intelligent distribution network.
