Seamless communication method between substation and dispatching master station

Abstract

The invention discloses a seamless communication method between a substation and a dispatching master station, comprising: setting an IEC61850 proxy server in the substation; adding the IEC61850 proxy server as an IED device to the SCD model of the substation; through the The IEC61850 proxy server simulates the IED devices in the substation; the master dispatching station communicates with the IED devices in the substation through the IEC61850 proxy server. The improvement of information transmission between the substation and the main station can be realized by the present invention, which can effectively solve the problem of accuracy and reliability of information transmission, seamless transmission of information and models, and provide high-quality basic information for many application functions of intelligent substations. Efficient information transmission and exchange methods, so as to build a good basic platform for power grid dispatching and monitoring.

Description

technical field [0001] The invention relates to the technical field of substations, in particular to a seamless communication method between a substation and a dispatching master station. Background technique [0002] The exchange of data information between the substation automation system and the dispatching and monitoring master station provides a basic guarantee for the operation monitoring of the power grid and the safe and economic operation of the entire network. However, due to the development and application direction and application depth of the substation automation system and the dispatching and monitoring master The difference is that the standard for flexible and dynamic transmission of panoramic information between the factory station and the control center has not yet been established. Currently, the main station and the factory station mainly use the information transmission protocol IEC60870-5-104 standard formulated between 1995 and 2002 for communication. ...

AI Technical Summary

Problems solved by technology

[0003] At present, the communication method between the substation and the dispatching master station still transmits the telecontrol information in a static way using data points and information tables, which cannot realize the real-time and dynamic unification and transmission of the power grid information model, which seriously restricts the development and application of power grid automation. Therefore, there is an urgent need for an automated information transmission technology to realize the seamless connection of automated information between smart substations and dispatching and monitoring master stations
