Full-process automatic access method of distribution automation terminal information

Abstract

The invention discloses a full-process automatic access method of distribution automation terminal information. While the existing distribution automation master station system architecture, functionand design of the distribution terminal, and the communication mode of the distribution automation are not changed, a high-efficiency feasible standardization access method of the distribution automation terminal information is put forward. Unified and standard intelligent distribution terminal information collection specifications are formulated; modeling of distribution terminal equipment is carried out; a distribution terminal information standardized template is established; a three-remote adaptive information point table template is formed; a terminal information point table is generatedand maintained automatically based on the template; and a main station terminal carries out access debugging on the terminals successively according to a field space sequence to realize IEC-61850-based full-automatic access of the IED intelligent distribution terminal. Therefore, rapid and automatic generation of the main information table of the distribution automation master station is realized;the post-stage system information maintenance workload is reduced; and the standardized management level of the terminal information meters of the distribution automation system is improved.

Description

technical field [0001] The present invention relates to the field of telecontrol information collection in the distribution network automation system. The description of the data model by using the IEC 61850-5-104 protocol and the distribution automation communication protocol is an application of the international standard IEC61850 in the distribution automation field, and specifically relates to a A whole-process automatic access method for distribution automation terminal information. Background technique [0002] With the continuous improvement of power supply safety and reliability requirements, the development of economy and society has put forward higher requirements for the technical level of distribution automation. The hot spot and focus of the current distribution automation technology research is how to make the terminal equipment produced by various manufacturers realize mutual information sharing to the greatest extent, avoid the phenomenon of "automation islan...

Problems solved by technology

Since the object models and collected information of terminal equipment from different manufacturers are not standardized and standardized, access to power distribution terminal information usually requires manual entry at the main station to establish an information relationship table mapping to achieve correspondence, or edit the information table in Excel format in advance and then import it in batches. The electrical automation system requires the on-site commissioning personnel of the power distribution master station and the terminal to check each piece of remote signaling, telemetry, and remote control information one by one. The workload is heavy, the test cycle is long, and the probability of error is high. Conducive to the large-scale construction and popularization and application of distribution automation system

Traditional methods have poor flexibility and heavy maintenance workload. How to safely and efficiently realize the effective access of a large number of distribution automation terminal equipment is always a difficult problem for distribution automation construction and operation and maintenance.
