广州电网调度自动化系统容灾备份研究

Research of disaster recovery and backup of Guangzhou power network SCADA system

电网调度自动化系统的运行可靠性和数据安全性要求日益提高,该文从应用功能、数据、通信系统等几个方面,阐述了广州电网调度自动化系统的容灾备份方案,着重介绍了多服务器冗余技术、数据备份技术和通信容灾技术等。实现了在部分服务器故障、存储设备故障和通信系统故障等故障条件下确保系统运行,提高了调度自动化系统的运行可靠性。

The requirement of the operational reliability and data security of SCADA system is increased quickly and the project for disaster recovery and backup is described from its application, data security and communication security. The technology of multi-server redundancy, data backup and disaster recovery of communication system are mainly introduced. The system is still available even if there are defaults in some part of the servers, storage device and communication device,which has highly improved its operational reliability.
