NB-IoT技术在电力行业的应用研究

Research on the Application of NB-IoT Technology in Power Industry

摘要: 作为低功耗广域网(Low Power Wide Area，LPWA)典型代表之一的窄带物联网NB-IoT技术具有广覆盖、大容量、低成本等特点，目前已在试商用阶段。同时，随着电力行业智能化的发展，海量的电力设备需要符合其通信特点的通信技术来进行信息交换与管理。本文首先介绍了NB-IoT技术在电力行业中应用的优势，从而进一步通过建模分析电力行业中具体电力业务对NB-IoT的需求。最后通过构建电力行业中农村与密集城区两个经典应用场景来对NB-IoT的覆盖进行仿真分析，给出NB-IoT组网部署方案。

Abstract: As one of the typical representatives of low-power wan (Low Power, Wide Area, LPWA) technology, NB-IoT is with wide coverage, large capacity, low cost and other characteristics, which is now in its trial commercial stage. At the same time, with the development of intelligent electric power in-dustry, huge amounts of power equipment need the technique that accords with its characteristics of the communication for information exchange and management. This paper first introduces the advantage of NB-IoT technology when it was applied in the electric power industry. Furthermore, the paper models and analyzes industry traffic requirement of specific power in the power industry. Finally, by building the classic application scenario of countryside and dense urban area in the electricity industry, the cover simulation analysis and network deployment scheme of the NB-IoT has been given.
