Plug-and-Play Method for Intelligent Substation Secondary Equipment Based on Flexible Matching

In response to the problem that the substation was low and the risk of detection was low due to the low construction efficiency and high risk of detection during the debugging, maintenance, and renovation phase, this paper proposes a plug-and-play scheme for automatic identification of flexible matching based on the characteristic dataset of communication protocols. First, design the secondary device to plug in and use the framework of the terminal to analyze the functional requirements of plug and play with the terminal. Secondly, the characteristics of the communication protocol in different data streams are extracted. Then, according to the characteristic library design communication rules, automatically identify the communication protocol. Finally, the designed terminal can be read correctly by functional testing.
