Abstract

The invention discloses an intelligent substation time monitoring method, system and device and a storage medium. The intelligent substation time monitoring method comprises the steps that time state monitoring is conducted on a time synchronization system, and time synchronization state monitoring is conducted on a time-served device; meanwhile, the time synchronization system adopts a GOOSE protocol mode to monitor the time synchronization deviation of the time-served device. According to the invention, the time synchronization monitoring of the time synchronization state is realized by completely utilizing the intelligent substation, and the monitoring time difference precision is millisecond level.

Description

technical field [0001] The invention relates to the field of time synchronization device monitoring, in particular to a time monitoring method, system, equipment and storage medium of an intelligent substation. Background technique [0002] The power system time synchronization system is the basis for various monitoring systems to perform data sampling, fault handling, network supervision, information management and accident recall and analysis, and is an important part of the safe operation of the system. If any node participating in the time has a time deviation problem, it may affect the stable operation of the system. In order to ensure that users can grasp the time running status in the system in real time, as well as the time synchronization status of computers, servers, switches, smart devices and other related systems involved in time synchronization in the system, it is very necessary to establish a complete time synchronization monitoring system . [0003] At pre...
