Application research of wireless RF-mesh network in low voltage distribution network

The low-voltage power distribution internet of things is an important infrastructure for smart power distribution, but it is difficult to choose from a variety of local communication technologies for low-voltage stations. This paper introduces an emerging wireless mesh network technology based on 802.15.4 and IPv6 suitable for low-voltage distribution internet-of-things, theoretically analyzes its transmission performance, and compares its technical advantages with other technologies, and reports field test results. The results of the pilot project show that the success rate of this technology to read user energy meters and low-voltage line collect transfer units can reach up to 99%, and the minimum can exceed 88%. Several tested services can successfully collect the data within 80% of days, and the topology recognition rate can reach 100%. Theoretical analysis and experimental results show that this technology is suitable for low-voltage distribution internet of things.
