摘要
针对电力无线通信在应用中存在的问题,为更好地服务智能电网和开展分时长期演进(time division long term evolution,TD-LTE)技术在电力通信等领域的应用研究,在TD-LTE网络结构基本原理的基础上,对无线专网架构和电力业务的业务模型进行分析。以实际案例为背景,通过数据处理方式和对比分析方法,比较1. 8 GHz和230 MHz两个频段LTE系统技术参数、理论分析以及现场测试的结果,验证电力无线专网对电力业务支撑能力,分析两个频段的无线专网系统的优缺点和适用场景。得出相关结论:LTE230M系统在郊区及农村有一定的覆盖优势,适合业务终端少、小颗粒区域专网建设; LTE1. 8G系统更适合城区、大颗粒业务区域专网建设。
Aiming at problems in application of power wireless communication and to better serve smart grids and develop application research on time division long term evolution( TD-LET) technology in field such as electric power communication,this paper analyzes framework of the wireless private network and the service model of power services on the basis of basic principle of TDLTE network structure. Taking actual cases for examples,it compares technical parameters of LTE systems with frequency bands of1. 8 GHz and 230 MHz and results of theoretical analysis and field tests by means of data processing and comparative analysis.Meanwhile,it verifies support ability of the power wireless private network for power services and analyzes advantages and disadvantages of two systems and their applicable scenes. It draws conclusions that the LTE230 Msystem has certain covering advantages in those surburbs and rural areas and is suitable for construction of private networks with fewer business terminals and in small particle areas,while the LET1. 8G system is more suitable for construction of private networks in cities and large particle areas.
