智能变电站网络安全防护应用研究

近年来,随着乌克兰电网遭受网络攻击等一系列事件的发生,变电站网络安全面临着一系列新挑战。目前变电站智能设备种类繁多,面临越趋严峻的非法访问、操作越权及数据篡改等内部网络威胁。因此,提出变电站智能设备的多维度网络安全防护机制,引入多级身份认证、分布式权限验、逆向矩阵等网络加固机制,解决常见的网络攻击问题。在不影响传输效率及性能的基础上确保智能设备网络访问与控制的安全性、可靠性及健壮性。

Application research on network security protection of an intelligent substation

In recent years,with the occurrence of a series of incidents such as network attacks on Ukraine's power grid,the network security of substations is facing a series of new challenges.At present,there are many kinds of intelligent equipment in a substation,and they face increasingly severe internal cyber threats such as unauthorized access,unauthorized operation and data modification.Therefore,a multi-dimensional network security protection mechanism for substation intelligent equipment is proposed,and the network reinforcement mechanisms such as multi-level identity authentication,distributed authority verification and reverse matrix are introduced to solve the common network attack problems.In order not to affect transmission efficiency and performance,the security,reliability and robustness of network access and control of intelligent equipment are ensured.
