In the power system

abnormal operation of time synchronization devices may lead to significant deviation between monitoring accuracy and actual situation

thereby affecting the overall monitoring effect. To address this issue

this article proposes the research and implementation of time synchronization device monitoring and evaluation technology based on power system network communication security. This method achieves monitoring and evaluation of power system time synchronization devices by designing hardware and software modules. In terms of hardware design

this article proposes key modules such as system authorization module

parameter management module

management unit module

and main clock monitoring hardware module. These modules work together to provide comprehensive monitoring and management capabilities for time synchronization devices. At the same time

based on the main clock monitoring hardware module

the system software part was further designed to collect time information parameters of the power system at regular intervals

and to timely identify device faults through anomaly recognition software. In addition

based on the identification results

combined with the device self check program

query program

communication interface program

and cyclic display program

the monitoring function of time synchronization for power secondary equipment is achieved. In terms of communication security

this method combines encryption algorithms and security authentication mechanisms to ensure the confidentiality and integrity of the communication process of the time synchronization device. By using encryption algorithms to encrypt the transmitted data and using security authentication mechanisms to verify the identities of both communication parties

while protecting the data

unauthorized access and attacks are prevented. The experimental results show that the accuracy deviation monitored by this method does not differ by more than 1 millisecond from the actual deviation

and the evaluation results are consistent with the actual results. This proves that the proposed method has strong real-time performance and stability. At the same time

combining appropriate communication security measures can ensure the data security and integrity of the time synchronization device during the communication process.
