Networking Technology of Plug-and-Play Multi-DT in Distribution IoT

The distribution Internet of Things (IoT) has realized the integration of heterogeneous devices and heterogeneous information. However, due to the difficult operation and maintenance by the diverse equipment, the existing research on the networking technology of multiple distribution terminals (DT) is less involved in optimizing the communication technology to improve the economy and communication reliability of networking. And the plug-and-play technology of distribution IoT equipment can effectively solve the engineering problems such as complex types of distribution equipment, long installation time, and large maintenance workload. It has broad application prospects. Therefore, this paper proposes a plug-and-play multi-DT networking technology for distribution IoT. Firstly, a multi-DT networking architecture based on IEC61850 standard is proposed; A multi-dimensional evaluation model and optimization technology are proposed to deal with the communication protocol difference of mass devices; Based on the above technical support, the multi-DT automatic networking technology of the distribution network of things is constructed. Finally, taking the 35kV distribution network in the Taishan District, Tai'an, China, as an example, the proposed method is verified to prove its effectiveness, to provide reference for the construction of the distribution IoT.
