基于LPWAN的泛在电力物联网

Ubiquitous power internet of things based on LPWAN

高比例的可再生能源接入、电力市场化改革和"互联网+"智慧能源的快速发展需要大量的数据支撑,并实现物理、商业、信息的广泛互联、智能互动。关键步骤之一是建立泛在电力物联网(Ubiquitous Power Internet of Things,UPIoT),实现电力系统中人与物、物与物、人与人之间随时随地通信。首先介绍了UPIoT的发展背景与基本概念、主要的低功耗广域网络(Low Power Wide Area Network, LPWAN)技术,然后以LoRa物联网解决方案为例介绍了基于LPWAN的UPIoT的体系架构及性能。最后探讨了UPIoT的应用前景,并指出了UPIoT需重点研究和解决的两个特殊问题,即:低压电力线载波通信(PLC)和强电磁干扰环境下的信号处理。

In the context of integration of high penetration renewable energy, electricity market reforms, and internet plus smart energy, massive data support is needed and the physical, commercial, and information interconnections of power(energy) grids must be strengthened. A key step is to construct the Ubiquitous Power Internet of Things(UPIoT), and realize the connections among people and things in the power system at anytime and anywhere. The development background and concept of UPIoT and the major Low Power Wide Area Network(LPWAN) technologies are introduced at first. Then the architecture and performance of LPWAN based UPIoT are elaborated by taking the LoRa IoT solution as an example. Finally, the application prospect of UPIoT is discussed, and the special problems of UPIoT, namely low-voltage power line carrier communication(PLC) and signal processing in strong electromagnetic interference environment are pointed out, which need to be further studied.
