支撑泛在物联的电力无线专网性能评估

针对无线通信技术受电磁干扰和通信安全限制在电力系统中的应用相对缓慢的情况,介绍了可支撑泛在物联的电力无线专网,根据电力新兴业务的通信需求,比较1.8 GHz和230 MHz TD-LTE系统的技术指标,选择前者作为工作频率构建无线专用网,并根据地形和通信需求设计了电力无线专网的建设方案。实测数据表明,任何1个基站发生故障后,信号覆盖率均能达到1 Mbit/s的要求,所建无线专网可为泛在电力物联网的发展提供有力的支撑。

Performance Evaluation of Electric Wireless Private Network Supporting Ubiquitous Power Internet of Things

Limited by electromagnetic interference and communication security, the application of wireless communication technology in power system is relatively slow. In this paper, an electric wireless private network for ubiquitous electric Internet of things is introduced. The communication demand put forward by emerging services is analyzed. By comparing the technical indicators between 1.8 GHz TD-LTE and 230 MHz TD-LTE systems, the former as the frequency to construct the wireless private network is selected in pilot area. The construction scheme of the distribution of base station is designed based on landforms and communication requirements. The measured data show that the signal coverage rate can meet the requirement of 1 Mbits with any single base station going wrong.and the built electric wireless private network can provide strong support for the development of ubiquitous electric Internet of things.
