Power distribution terminal self-description method based on IEC61850 standard

Abstract

The invention discloses a power distribution terminal self-description method based on IEC61850 standard. The power distribution terminal self-description method comprises the following steps of (1), writing a self-description file into a power distribution terminal file system; (2) establishing communication between a power distribution terminal and a power distribution main station, and actively applying a registration service by the power distribution terminal to the power distribution main station; (3) establishing a data model by the power distribution main station for the power distribution terminal according to power distribution terminal registration information, performing mapping for obtaining a subscription model, and transmitting the subscription model to the power distribution terminal; (4) automatically generating a communication point table by the power distribution terminal; and (5) triggering the power distribution terminal by the power distribution main station for starting a self-error-correction module, determining whether a subscription point number matches a point number which is supplied by the terminal and whether correct matching is performed through comparing the subscription model, the self-description file, the point number of the communication point table and a data domain name, and uploading the result to the power distribution main station. The power distribution terminal self-description method has function of improving efficiency and reliability in construction of a power distribution network, and laying a foundation for realizing a plug-and-plug function between the power distribution main station and the power distribution terminal.

Description

technical field [0001] The invention relates to a power distribution terminal self-describing method applied in a power distribution automation system with a plug-and-play function, in particular to a power distribution terminal self-describing method based on the IEC61850 standard, and belongs to the technical field of power systems and automation thereof. Background technique [0002] As an important part of the smart grid construction, the smart distribution network integrates modern computer technology and communication network technology to monitor, coordinate and control the equipment on the distribution network in real time. This is the modernization development of the power system. The inevitable trend. As the key equipment of the intelligent distribution network, the distribution terminal completes the information exchange between each other and the master station of distribution network automation through the communication system. At present, the "three remote" da...

AI Technical Summary

Problems solved by technology

At present, the "three remote" data between the power distribution terminal and the main power distribution station need to manually check the data point table. The access of a large number of power distribution terminals leads to a very large workload for the automatic construction and maintenance of the distribution network.
