Abstract

The invention discloses a data communication gateway real-time database generation method, which comprises the following steps of: hierarchically analyzing an SCD (Substation Configuration Description) model of a transformer substation, establishing a hierarchical chain table based on a shared memory, establishing a dynamic data set, and packaging the shared memory to form a data set for external application subscription and access. Seamless connection of a data communication gateway to lower acquisition interval data and to upper support of a substation master station data set on-demand request is realized, a subscribed dynamic data set of substation voltage class, interval data, primary equipment, secondary equipment and data set FCDA measuring point information in the secondary equipment is supported, and an on-demand access target is realized. The data processing time is reduced, the data forwarding efficiency of the data communication gateway is improved, and the requirement of the transformer substation master station for high real-time performance of transformer substation data is met.

Description

technical field [0001] The invention relates to the technical field of electric power data communication, in particular to a method for generating a real-time database of a data communication gateway. Background technique [0002] At present, the data communication of power substations generally uses remote signaling, telemetry, remote control and remote adjustment data. The interaction between the main factory substations basically adopts the protocol of telecontrol 101 or 104 of the point table, and the data organization method in the data gateway machine. With protocol communication as the goal, real-time data is stored through a two-dimensional memory table. At the same time, the data communication gateway uses the IEC61850 client to collect the real-time data of the spacer, and forwards the four-remote data through the 104 protocol. In the data communication gateway machine, it is necessary to perform two data conversions between the object-oriented model based on IEC6...
