Research on plug and play method of distribution transformer station intelligent fusion terminal

With the access of a large number of intelligent fusion terminals and low-voltage monitoring terminals in the station area, the traditional manual debugging and point-to- point meter method cannot meet the requirements of construction and operation, digital Technology is urgently needed to realize word description, self-registration and self- recognition of intelligent fusion terminal and low-voltage monitoring terminal. For these reasons, this paper proposes a plug-and-play method for the intelligent fusion terminal in the station area and the low-voltage monitoring terminal. First, it introduces the "cloud-pipe-side-end" system architecture of the distribution Internet of Things, and analyzes the technical route based on IEC61850 applied to distribution automation, proposed "cloud-side" plug-and-play and "side-end" plug- and-play systems and implementation methods, finally, an example is used to verify the correctness and effectiveness of the proposed method.
