Access method of power distribution terminal equipment information

Abstract

The invention relates to an access method of power distribution terminal equipment information. The access method comprises the following specific steps of: A, setting an equipment interval list in a database, and listing names and information table templates of the power distribution terminal equipment to be selected and used in the equipment interval list; B, performing wire connection on the power distribution terminal equipment in a power distribution facility based on a single line diagram of a power distribution network; C, calling the equipment interval list in the step A from the database, selecting the name of the power distribution terminal equipment in the equipment interval list, and enabling the interval sequence to be in one-to-one correspondence with the interval name based on the wire connecting sequence in the step B; D, extracting related fields in the database by a master station and sequentially splicing the related fields to form measurement information, and enabling the measurement information to be in one-to-one correspondence with a dot mark to generate an information table of the master station. The access method of the power distribution terminal equipment has the characteristics of being standard and formal, and can greatly improve maintenance efficiency, accuracy and normalization of the information table of the master station.

Description

technical field [0001] The invention relates to an information collection and information processing method for power distribution terminal equipment, and belongs to the field of power distribution technology. Background technique [0002] The power distribution terminals of the power distribution automation system are often produced by many different manufacturers, with different models and types. The communication protocols used are different, and the amount of information is huge. The number of remote signaling, telemetry, and alarm information is usually higher than that of dispatching automation. The system is an order of magnitude, and the distribution lines and corresponding distribution terminals are frequently changed and changed. [0003] At present, access to power distribution terminal information usually needs to be entered manually at the main station, and the information relationship table mapping is manually established to achieve one-to-one correspondence. ...

Problems solved by technology

[0007] However, since the distribution automation systems currently in service are not based on the IEC61850 standard, to carry out the construction of distribution automation according to the above research results, it is necessary to make comparisons between the distribution automation master station system, substation system, terminal equipment, and communication system. A large-scale transformation or even a complete redesign will be more difficult to achieve in the short term
