Abstract

Abstract: In order to improve the data communication reliability and the data channel redundancy of smart grid power dispatching automation system, the main & spare channel for gathering and transmitting information is applied in the today’s power system, which consequently leads to asynchronous between dispatching automation system and receiving frequency. A new method is presented in this paper, which can intelligently match the power dispatching automation system with the main & spare channel information. The interactive communication message between power dispatching automation system and substation is obtained through network monitoring. The intelligent alignment algorithm is used to compare such communication protocol parameters as remote state, telemetry, SOE, remote control and remote adjustment, and the alarm event is outputted timely according to the compared result. The proposed method is effective in monitoring the quality of main & spare channel communication and detecting the channel abnormalities, and can greatly improve the efficiency of the dispatching automation system.

Key words: smart grid, dispatching automation system, main & spare channel, information matching, telecontrol protocol
