Abstract: A substation area control system based on generic object oriented substation event（GOOSE） message at the station level is firstly proposed and realized.The proposed system consists of the bay device,monitor and control subsystem and substation area control subsystem.The system transfers GOOSE message of the station level by double redundant computer of manufacturing message specification（MMS） network at the station level,and realizes functions such as backup power automatic switching,overload cut-off,overload blocking in smart substations.The system enhances the real-time of substation area control actions,and could replace devices and systems such as backup power automatic switching and overload cut-off.This system has been applied in many smart substations.
