为避免各类因素造成调度自动化系统故障和数据丢失,研究了一套调度自动化系统紧急容灾备份方案.调度主系统设在调度大楼,主站备份系统设在远离主系统的异地.正常运行时,所有变电站等现场信息向2套系统同时传送数据;当调度主站系统发生故障时,现场信息依然可以传送给备份系统;调度主站系统恢复正常后,备份系统可将故障期间的数据信息导入调度主系统.给出了该方案实现流程图.所研制的系统已安装在某220 kV变电站投运,当调度主站系统故障时,紧急容灾备份系统及时、准确地保存了数据,表明该方案是可行的.

To avoid the failure and data loss of dispatch automation system due to different factors,an emergency scheme of anti-disaster backup is studied.The main dispatch system is located in dispatch building while the backup system is located far away from the building.During normal operation,site information is transmitted to both systems at the same time.When the main dispatch system fails,the site information is still transmitted to the backup system.When the main dispatch system recovers to normal,the data during failure is transferred from the backup system into the main system.Its implementation flowchart is provided and the developed system is operating in a 220 kV substation.During the main dispatch system failure,the emergency anti-disaster backup system timely and accurately saves the data,showing its feasibility.
