Method and system for power distribution master station to automatically identify terminal device

Abstract

The invention relates to a method and system for a power distribution master station to automatically identify a terminal device. The method comprises the following steps that: step 1, a power distribution terminal initiatively submits registration information to a power distribution automation master station, so that the registration of the power distribution terminal can be completed; step 2, the front end server of the power distribution automation master station automatically discovers the on-line registered power distribution terminal and creates an underlying communication link so as to provide point-to-point communication services for the communication interaction of the two parties; step 3, the power distribution terminal uploads an IEC61850 standard-based SCL self-description model file to the power distribution automation master station; and step 4, the power distribution automation master station resolves the SCL self-description model file information, then updates database model information, and performs mapping association on the secondary measurement model information of the power distribution terminal and an IEC61968 model in the power distribution automation master station. With the method and system of the invention adopted, 104 protocol message resources can be utilized to make the power distribution automation master station automatically discovery and automatically identify the power distribution terminal.

Description

technical field [0001] The invention belongs to the technical field of telecontrol information collection of distribution network automation systems, and relates to an application of the international standard IEC61850 in the field of distribution automation, in particular to an automatic identification method and system for terminal equipment by a distribution master station. Background technique [0002] With the development of digitalization, informatization, automation, interaction and intelligence of the distribution network, the intelligent distribution network integrating modern computer, communication network, power system control and other technologies has a great impact on the intelligent terminal equipment in the distribution network. There is an urgent need for technologies for remote real-time monitoring, control, coordination and maintenance. This puts higher demands on the power distribution system: [0003] (1) The data sent by the power distribution termina...

Problems solved by technology

It relies on manual transmission of remote signaling, telemetry, and remote control point tables, and then conducts a point-by-point test check between the main station and the terminal, and then the main station manually enters the information point table into the database. Not only does the meaning of the data not clear, various data There is no strong correlation between them; and when a new terminal is added to the power distribution system or a terminal fails, it cannot be discovered in time and corresponding measures can be taken

Ultimately, the automatic identification of power distribution terminals according to the IEC60870-5-104 protocol cannot be realized between the master station and the terminal, and between the terminals. This is one of the key issues in plug-and-play technology. is of great significance
