中文摘要:

在电力系统中，时间同步装置的异常运行可能导致监测精度偏差与实际偏差较大，从而影响整体监测效果。为解决这一问题，本文提出了基于电力系统网络通信安全的时间同步装置监测与评估技术研究与实现。该方法通过设计硬件和软件模块，实现对电力系统时间同步装置的监测和评估。在硬件设计方面，本文方法设计了系统授权模块、参数管理模块、管理单元模块和主时钟监测硬件模块等关键模块。这些模块协同工作，提供了对时间同步装置的全面监测和管理能力。同时，在主时钟监测硬件模块的基础上，进一步设计了系统软件部分，定时采集电力系统的时间信息参数，并通过异常识别软件对装置故障进行及时识别。此外，根据识别结果，结合设备自检程序、查询程序、通信接口程序和循环显示程序，实现电力二次设备时间同步的监测功能。在通信安全方面，本文方法结合加密算法和安全认证机制，确保时间同步装置的通信过程中的保密性和完整性。通过使用加密算法对传输的数据进行加密，并使用安全认证机制验证通信双方的身份，在保护数据的同时，防止未经授权的访问和攻击。实验结果表明，本文方法监测出的精度偏差与实际偏差相差不大于1毫秒，评估结果与实际结果一致。这证明了本文方法具有较强的实时性和稳定性。同时，结合适当的通信安全措施，可以确保时间同步装置在通信过程中的数据安全和完整性。

英文摘要:

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.
