Research on Network Security Risk Analysis and Prevention and Control Technology of Protection Debugging Tool Accessing Secondary Equipment

文章通过对电力系统相关安全防护等规定的研究,以及当前变电站继电保护装置调试过程中存在的问题和调试过程的特点,提出开发继电保护装置专用调试工具、变电站调试工具安全管控装置及对应的方案策略,其中包括安全审计和可验证技术、安全隔离和边界防护技术、过程监视和管控技术、调试过程监视和管控技术等功能要求。通过这些技术确保调试工具和二次设备之间逻辑强隔离,彻底实现内、外网之间的安全防护,提高了调试过程的管控能力,增强了电网的信息安全防御能力,保障了变电站的安全稳定运行与维护。

In this paper, through the research on the relevant security protection regulations of power system, as well as the problems existing in the commissioning process of substation relay protection devices and the characteristics of the commissioning process, this paper proposes the development of special debugging tools for relay protection devices, safety control devices for substation debugging tools and corresponding scheme strategies, including security audit and verifiable technology, safety isolation and boundary protection functional requirements of protection technology, process monitoring and control technology, commissioning process monitoring and control technology. Through these technologies, the logical strong isolation between the debugging tools and the secondary equipment is ensured, the security protection between the internal and external networks is completely realized, the control ability of the commissioning process is improved, the information security defense ability of the power grid is enhanced, and the safe and stable operation and maintenance of the substation are guaranteed.
