摘要
通过二次防护的改造,将自动化实施系统与MIS网进行了物理隔离,有效地阻止了黑客入侵及网络病毒的侵入,减少了网络事故,杜绝了可能发生的电网解列事故,从而避免了大面积停电带来的经济损失,保障了电网安全运行。
By way of secondary protection, automation execution system and MIS net was physically separated to effectively prevent Hacker and network virus from invasion, reduce network accident, and stop occurrence of possible accident of electric network dissociation, thereby to avoid economic loss caused by power cut in large area and protect safe running of electric network.
