目前的智能变电站在信息安全方面的防护十分薄弱,通信协议普遍缺乏安全措施。由于网络化通信方式的大量应用以及通信协议的标准化,智能变电站很难对蓄意攻击做出有效的防护。基于IEC 62351提出了增强智能变电站信息安全的设计,并制作了原型系统进行实现。近年来国家大力发展智能电网,变电站的智能化已成为电网发展的方向。智能变电站的主要特
At present, the protection of intelligent substation in information security is very weak, and communication protocols generally lack of security measures. Due to the large number of applications of networked communication methods and the standardization of communication protocols, it is very hard for intelligent substations to effectively protect against intentional attacks. Based on IEC 62351, the design of information security in smart substation is proposed and a prototype system is made to realize it. In recent years, the state vigorously develop the smart grid, intelligent substation has become the direction of grid development. The main characteristics of smart substation
