【 摘 要 】

In order to change the status quo within the substation bay control devices which only passive receiving IRIG-B GPS clock code or PPS, for the purpose of the research and the realization method of substation clock unsynchrony alarm system based on GPS pulse. On the basis of existing substation SCADA system and GPS time synchronization system, this paper realizes the real-time monitoring of time synchronization of substation bay control devices by simple modification and introduction of simple algorithm. This paper describes in detail the system construction method and relative time difference algorithm, as well as the project implementation method, to achieve the correct and punctual on-line monitoring of the bay control device, effective control of substation accidents caused by device time unsynchrony, greatly improving the stability of substation operation.
