Abstract

The invention discloses an automatic time-tick synchronization system of intelligent electronic equipment of a transformer substation in the technical filed of automatic time-tick of intelligent electronic equipment of a transformer substation in the power sector. The automatic time-tick synchronization system comprises a time-tick server and a time-tick terminal installed on the intelligent electronic equipment of the transformer substation. The time-tick server comprises a UTC (Universal Time Coordinated) acquisition unit, a central processing unit supporting an IEEE1588 protocol and a network interface supporting IEEE1588 protocol communication; the time-tick terminal comprises a protection unit based on IEC61850 modeling, a central processing unit supporting the IEEE1588 protocol and a network interface supporting IEEE1588 protocol communication; and the time-tick server and the time terminal are connected by the network interfaces supporting IEEE1588 protocol communication. The invention avoids the problems of complicated network structure and overhigh cost of the traditional time-tick system and improves the accuracy of clock synchronization.

Description

technical field [0001] The invention belongs to the technical field of automatic time synchronization of intelligent electronic equipment in substations in the electric power industry, and in particular relates to an automatic time synchronization system for intelligent electronic equipment in substations. Background technique [0002] At present, the time synchronization system of conventional substation integrated automation equipment basically adopts the method of combining direct time synchronization and network time synchronization. All kinds of IEDs (Intelligent Electronic Devices) in substations adopt digital processing technology, and the internal crystal oscillator circuit can add time stamp information when outputting information. However, in practical applications, the time accumulation of different IEDs will occur. The problem that causes the time error to increase. The traditional time synchronization method is to synchronize the time of the master station firs...
