摘要
汽轮机是燃煤发电机组的三大主设备之一,而汽轮机控制保护逻辑是实现汽轮机主要控制和保护功能的载体,可能成为网络安全攻击的目标。本文通过介绍控制保护逻辑的基本原理及其工程实现,提出了一种针对汽轮机控制保护逻辑的网络安全攻击方法,并分析了网络安全攻击对汽轮机运行的危害,最后通过基于仿真实验平台的网络安全攻击实验,验证了针对控制保护逻辑的网络安全攻击能够危害汽轮机的正常运行,提出了强化控制系统通信鉴权的建议。
Steam turbine is one of the three major components in coal-fired generating units.As the carrier of steam turbine control and protection function,control and protection logic is likely to be the target of cyber attack.This paper introduces its basic principle and engineering implement,proposes the cyber attack methods for control and protection logic,and also analyzes the damage for a running steam turbine.Finally,some cyber attack experiments are performed by using cyber security simulation testbed.The experiment results illustrate that cyber attack on control and protection logic endangers the safety of steam turbine,and proposes some suggestions to strengthen the authentication management of communication in the control and protection system for steam turbine.
