Problems solved by technology

At present, the power distribution terminal has not been standardized and lacks a unified model. Most distribution automation systems use IEC104 or IEC101 telecontrol communication protocols. These communication protocols only solve the problem of data transmission, lacking description and explanation of the data itself. The master station system cannot obtain the actual meaning of the statute data; when the power distribution terminal is connected, it relies on manual production and manual transmission of remote signaling, telemetry, and remote control point tables,

Embodiment Construction

[0024] The present invention will be further described below in conjunction with specific examples.

[0025] In order to realize the plug-and-play of distribution automation terminals, the distribution automation system is divided into distribution automation master station layer, distribution terminal layer and process layer, such as figure 1 Shown:

[0026] (1) Distribution automation master station layer

[0027] The distribution automation master station is the core of the entire distribution automation system, and the front-end server is the data communication bridge between the distribution automation master station system and the distribution terminal, which converts the data sent by various types of terminals into the main The data inside the station system realizes the plug-and-play function of the power distribution terminal. The front-end server is mainly equipped with a power distribution terminal discovery module, a power distribution terminal resource allocation...

Abstract

The invention discloses a plug-and-play method of power distribution terminals based on an IEC61850 standard. The method comprises the steps of putting forward a model mapping method between a power distribution automation master station and the power distribution terminals by adopting an idea of IEC61850 object orientation and layering distribution, on the basis of an open IP (Internet Protocol) communication network and on the premise of self-description of the power distribution terminals, constructing a power distribution automation terminal plug-and-play system, and achieving plug-and-play of the power distribution terminals. The plug-and-play method of the power distribution terminals based on the IEC61850 standard achieves automatic discovery and automatic identification of a power distribution automation master station system to the power distribution terminals, reduces a large amount of work in installation and debugging processes of the power distribution automation terminals, provides a model basis for mutual identification between the power distribution automation terminals, and promotes rapid development of intelligent distributed FA (Feed Automation).

Description

technical field [0001] The invention relates to the field of telecontrol information collection in distribution network automation systems, is an application of the international standard IEC61850 in the field of distribution automation, and specifically relates to a plug-and-play method for power distribution terminals based on the IEC61850 standard. Background technique [0002] With the increasing coverage of distribution automation year by year, the number of distribution automation terminals is increasing day by day. At present, the power distribution terminal has not been standardized and lacks a unified model. Most distribution automation systems use IEC104 or IEC101 telecontrol communication protocols. These communication protocols only solve the problem of data transmission, lacking description and explanation of the data itself. The master station system cannot obtain the actual meaning of the statute data; when the power distribution terminal is connected, it reli...
