Problems solved by technology

However, at present, there are still differences in the modeling, information interaction, and transmission mechanisms of the time synchronization monitoring system among the main and substation equipment manufacturers, resulting in the inability to truly synchronize the time of the power system, and the corresponding data analysis and processing cannot be guaranteed to be reliable. It is urgent to use technical means to assist in the development Laboratory testing, assisting in on-site troubleshooting and analysis, ensuring reliable acceptance of on-site equipment network access and improving on-site acceptance efficiency

Description

technical field [0001] The invention relates to the technical field of power system time synchronization monitoring, in particular to a time synchronization monitoring and testing device and method. Background technique [0002] At present, the conventional time synchronization system only has one-way time service, and lacks time synchronization monitoring and management functions. For this reason, the prior art has proposed a time synchronization monitoring implementation scheme, and stipulated a clock monitoring equipment modeling specification, so as to carry out the deployment of the time synchronization monitoring system. The time synchronization monitoring system needs to realize the time synchronization of the time synchronization device and secondary equipment of the whole network, so as to support the reliable collection, processing, management and analysis of the remote signaling and telemetry information of the device itself. However, at present, there are still ...
