Study On Application Of TD-LTE Technology In Smart Gird

The smart grid is the development trend of the future power grid,due to China's power generation network,transmission network started early and relatively mature.The development of distribution network is relatively lagging due to the imbalance of resource distribution,which forms the situation of uncoordinated development of power grid,transmission network and distribution network.Intelligent distribution network has become a bottleneck restricting the further development of China's power grid.In this paper,according to the characteristics of the distribution network in Dongguan,the paper studies the intelligent construction of Dongguan distribution network on the premise of studying the relevant data of the transformation and upgrading of the foreign intelligent distribution network.The reconstruction of Dongguan distribution network presents the situation of complex structure,large number of equipment,poor anti-interference ability,and the current communication mode of distribution network can not meet the requirements of the intelligent construction of distribution network.Based on communication network construction of intelligent distribution network upgrade to the entrance of Dongguan City smart grid communication network construction of power network are studied in detail,mainly consider the fourth generation of TD-LTE technology,and the key points of this technology are explained.Finally,this paper puts forward a set of communication network construction scheme,which is suitable for the situation of Dongguan distribution network and the development of complex intelligent distribution network.The main structure of this paper is as follows:Firstly,the paper introduces the development of communication technology in distribution network,and puts forward the necessity of building a special wireless communication network in Dongguan.Secondly,the paper introduces the basic theory of the TD-LTE technology,the key technology and the requirements of the auxiliary hardware.Thirdly,the paper analyzes the existing problems of Dongguan distribution network communication,and puts forward the corresponding solutions to solve these problems,the overall design of wireless broadband network architecture based on TD-LTE technology,the network plan,the two aspects of the business requirements are analyzed in detail.Lastlt,according to the technical proposal put forward in the above,the author makes the field construction of the business demand,and analyzes the simulation results.
