摘要:

信息物理的紧密耦合使网络安全问题成为电力系统安全稳定运行的重大挑战,同时也给信息物理的协调感知和安全防御提供了新的潜力。围绕安全稳定控制业务,针对信息物理融合带来的网络安全问题,挖掘信息物理协调的潜力,提出信息物理协调防御的框架,提升安全稳定控制系统防御恶意攻击的能力。首先,通过试验分析了恶意攻击对电网安全稳定控制系统和电力一次系统产生的影响。在此基础上,分别从时间和空间维度提出了网络安全信息物理协调防御体系和框架,并结合传统网络安全技术和安全稳定控制业务逻辑分别提出了包含装置侧和主站侧的网络安全辨识和防护方案,给出了安全稳定控制系统网络安全监视与分析应用框架,从而提升了安全稳定控制系统应对恶意攻击的能力。

Abstract:

The close cyber-physical coupling makes network security problems a major challenge to the safe and stable operation of power systems, and it also provides new potential for the cyber-physical coordinated perception and security defense. Focusing on the security and stability control business, aiming at the network security problems brought by cyber-physical integration, this paper excavates the potential of cyber-physical coordination, puts forward the framework of cyber-physical coordinated defense, and improves the ability of security and stability control systems to defend against malicious attacks. Firstly, the impacts of malicious attacks on power security and stability control systems and power primary systems are analyzed through experiments. On this basis, the cyber-physical coordinated defense system and framework for network security are proposed from the time and spatial dimensions, respectively. Combined with the traditional network security technology and security and stability control business logic, the network security identification and protection schemes including device-side- and master-station-side schemes are proposed, respectively, and the network security monitoring and analysis application framework of the security and stability control system is given, so as to improve the ability of the security and stability control system to deal with malicious attacks.
