电力调度自动化系统安全运维网络的设计与实现

Design and Realization of Security Operation & maintenance Network of Power Dispatching Automation System

为降低电力调度中心运维工作的各项安全风险,设计了一种安全设备、运维设备专用的网络结构。该网络可与现有的调度自动化系统网络共同工作,并能对安全设备、运维设备的网络连接进行精细地访问控制,有效降低各项安全风险。此外,该网络还可方便地对上下级调度中心的安全防护系统进行统一管理,为安全态势感知等高级应用提供支持。应用效果表明,安全运维网络有效降低了恶意代码传播、IP地址冲突等风险,大大提升了系统安全性和运维效率。

In order to reduce risks of operation & maintenance work in the power dispatching control center, a special network structure for security equipment and operation & maintenance equipment is designed. The network can work with the existing network of power dispatching automation system and can provide precise access control for the network connections to security equipment and operation & maintenance equipment which effectively reduces risks. In addition, the network can also conveniently make unified management of security protection systems among upper and lower level dispatching control centers and provide advanced application support including the security situation awareness and so on. Application effects show that the security operation & maintenance network effectively reduces risks such as malicious code propagation, IP address conflict and so on which greatly improve the system security and operation & maintenance efficiency.
