Abstract

The on-line monitoring of time synchronization system in Smart Substation is the key point to solve the time traceability of smart substation. Analyze current status of time synchronization in substation time synchronization system. Point out the defects of low time precision, abnormal synchronization and time service of microsecond equipment. Propose a method of synchronous closed-loop monitoring of substation automation equipment calibration method based on time, by the state monitoring module, connection time, send port part time information part, return time status information, time deviation calculation part, determine the abnormal and error and time error correcting part is composed of seven parts. Analyze the principle and implementation method. Propose the time information flow for actual substation. Through close loop check, the time condition of substation automation equipment can be accurately detected, and solve the clock synchronization problem of intelligent substation.
