摘要:
 截止目前,电力系统已经在一些地区开展了LTE专网系统试点工程建设工作.试点工程应用的LTE系统包括LTE230系统和LTE1800系统,主要采用单频组网的建设模式,而工作在不同频段的LTE系统受频率等特性影响,适应不同的应用场景,不能完全满足电力系统的应用需求.为充分发挥不同系统的优势,开展了LTE230系统和LTE1800系统的异频组网系统应用研究.考虑到电力系统有限的专用频段,为提高频谱利用率,给出了电力LTE系统双工模式选择建议和理由.在综合分析LTE230和LTE1800系统优缺点的基础上,提出了基于两种LTE系统的异频组网架构,研究了在此架构下基于蜂窝网络之间的负载均衡和基于D2 D直连通信的业务分流方法,并对异构系统的天线融合方法进行了简要介绍.此外,结合电力系统的应用需求、LTE系统特性和异构网络研究现状,对两种LTE系统的异频组网方案在电力系统中的应用所存在的难点问题进行了探讨.
Abstract:
 So far,the electric power system has been carried out pilot projects of dedicated LTE network in some regions. The LTE system in the application of pilot projects includes LTE230 and LTE1800,and both of them are single-frequency networking in the network con-struction. However,different system has different application scenes according to the characteristic such as frequency,which cannot fully meet the application requirements of the power system. In order to give full play the advantages of different systems,the study on differ-frequency networking scheme of LTE230 system and LTE1800 system is conducted. Taking into account the limited frequency band of the power system,in order to improve the spectrum utilization,the advice and reasons of duplex mode selection are given. Based on the comprehensive analysis of the advantages and disadvantages of LTE230 and LTE1800 system,the differ-frequency networking architec-ture of the two systems are put forward,the service distributing method of load balancing between the cellular network and D2D direct communication service under the network architecture is studied,and antenna fusion scheme is introduced briefly. In addition,combined with the application requirements of power system,the characteristics of LTE system and the research status of heterogeneous network,the difficulty of differ-frequency network applied in electric power system is discussed.
