摘要
针对目前电网潮流分布复杂,网络安全防御难度大,在攻防应对过程中存在识别率低、阻断可靠性无法保证等问题,借鉴继电保护思想,设计实现面向源网荷互动的多级后备自动阻断系统。系统能够通过入侵检测、路径重构、策略下发以及分布式阻断等措施对网络攻击进行阻断。整个阻断过程灵活且方便控制,对于源网荷工控系统安全稳定运行具有一定现实意义。
In view of the complex distribution of power flow in the current power grid,the difficulty of network security defense,the low recognition rate in the attack and defense response process,the failure to ensure blocking reliability and other problems,a multi-level backup automatic blocking system oriented to source network load interaction is designed and implemented based on the idea of relay protection.The system can block network attacks through intrusion detection,path reconstruction,policy distribution,distributed blocking and other measures.The whole blocking process is flexible and convenient to control,which has certain practical significance for the safe and stable operation of the source network load industrial control system.
