The clock synchronization technologies applied to controlling layer and primary equipment like intelligent switchgear of processing layer in intelligent substation are analyzed in this paper. IEEE1588 message timing mode, which can be accurate to nanosecond, is used as the mode of substation system, in order to fulfill the real-time and accuracy requirements of intelligent switchgears and remote control...
An object-oriented technology was utilized for smart vacuum circuit breaker physical structure and function (service) based on IEC61850 standard. The information model of intelligent vacuum breaker was established to integrate the measuring information flow of field parameters, the monitoring information flow of status data and the operating and controlling information flow. The status parameter of...
