A method for source end maintenance and plug-and-play of equipment in low-voltage distribution and transformer area

Abstract

The invention discloses a method for source end maintenance and plug-and-play of equipment in a low-voltage distribution and transformer station area. The topology of electrical primary equipment and the information corresponding to the low-voltage monitoring terminal and branch monitoring unit are then transferred to the DMS master station; after the low-voltage monitoring terminal is powered on, it directly initiates a communication connection with the DMS master station, and registers the low-voltage monitoring terminal information in the local area; DMS After the master station receives the registration information of the station area, it sends the equipment file of the station area to the low-voltage monitoring terminal of the station area. The equipment file includes: equipment serial number, equipment type and equipment ID; the low-voltage monitoring terminal adopts the DMS master station The transmitted equipment file information communicates with the connected branch monitoring unit to realize the interaction between the main and sub-stations of the monitoring information in the station area. This method can solve the problems of inaccurate information of the master station and complicated configuration of the station area. It has a clear structure, strong operability, and lower requirements for engineering and technical personnel.

Description

technical field [0001] The invention belongs to the field of distribution network automation, and in particular relates to an implementation scheme of an automation system for a low-voltage distribution transformer station area. Background technique [0002] With the continuous development of power grid construction, the infrastructure of the distribution network has been greatly improved, and the original extensive management has gradually turned to refined management, and the construction of intelligent low-voltage station areas has become a trend. The general solution is to install low-voltage monitoring terminals in the station area to monitor the electrical quantities on the incoming side of low-voltage transformers, install branch monitoring units at branch switches or transform into smart switches to monitor the electrical quantities of branch lines, and the branch monitoring units communicate with low-voltage monitoring terminals through communication cables. communi...
