摘要
随着现代电力生产控制系统的高度信息化、网络化,保障电力生产控制系统的信息安全已成为电力系统安全稳定运行的重要前提[1]。三门核电数字化仪控系统用于电厂状态监测、数据传输和电厂控制功能,一旦受到攻击将导致核电站停堆等一系列严重后果。三门核电采用AP1000技术,数字化仪控系统(分散控制与信息系统)采用Ovation控制平台。Ovation控制平台由服务器、工作站、交换机等核心设备搭建组成。本文首先对Ovation控制平台核心设备服务器、工作站、交换机进行介绍,然后对等级保护测评主要内容逐一归类分析。最后结合等级保护测评结果,根据电厂实际情况,落实等级保护改进项,消防安全隐患,保障三门核电数字化仪控系统整体信息安全。
The information security is an important premise to ensure safe and stable operation of the electric production control system with modern electric production highly informatization and networked. The digital instrument and control system of Sanmen Nuclear Power Company is used for plant status monitor, data transmission and plant control. It could have serious consequences, such as nuclear reactor trip, once the system is under attack. AP1000 technology is used for Sanmen Nuclear Power Company. The Ovation control platform is used for instrument and control system (Distributed control and information system). Ovation platform contains server, workstation, and switch. This article introduce the core equipment of Ovation platform at first, such as server, workstation, and switch. It analyzes the level protection evaluation for digital instrument and control system. At last, it states the non-conforming items of level protection evaluation, which can be eliminated to improve the information security for digital instrument and control system.
