摘　　要：数据备份是任何自动化系统在设计之初就必须考虑的项目。能量管理系统(EMS)对备份的数据量、备份的版本、备份及恢复的时间有其特殊的需求,而常用的商用备份工具不能满足EMS的运行需求,同时,目前的商用备份软件不支持时间序列数据库。文中对电力系统EMS数据备份方案进行研究,制定出一套符合电力系统安全生产要求的备份及恢复策略,并已在南方电网网调EMS中投入实际运行。The database backup should be considered at the beginning of automation system design. The energy management system （EMS） has special requirements for data scream, backup version, backup time and restoring time. Therefore the commonly used commercial backup tools can＇ t meet the operational requirements of EMS. Besides, the current commercial backup softwares don＇ t support the time-series databases. This paper studied the schemes of the data backup in power system EMS, and proposed a feasible data backup and recovery strategy, which complied with the power system security requirements, and been put into practice in China Southern Power Grid EMS.
