灾难事件的发生对电网调度自动化系统造成损害,使得电网监控和调度中断、电网运行失去控制,对所属区域电网造成极大的影响。智能电网的提出对电网可靠性与容灾能力提出了新的要求,迫切需要建立电网调度自动化灾备系统,以提高电网运行的防灾能力。首先,建立了电网调度灾备系统的评价模型,然后,针对电网系统中存在的各种备用方案进行优化分析,提出了基于统一调度数据网构建集控/调度互备的备用方案。针对一体化互备的方案搭建了基于云平台的灾备系统结构,结合虚拟化、服务化等云计算技术,有效地兼容与保护了现有灾备软硬件资源,并面向灾备基础软件、基础服务、支撑应用与应用服务4个层次,设计了一套基于统一管理界面、系统增量同步、动态扩容的电网集控/调度一体化互备系统解决方案。

Damages to the energy management system(EMS)due to disasters not only contribute to interruption of grid surveillance and control,but also make the grid operation out of control,exerting extremely serious influence on some grid areas it belongs to.The proposition of the smart grid has led to new requirements on the reliability of the smart grid and disaster recovery capabilities.The establishment of the EMS disaster recovery system is badly needed to improve the preventive ability of the state grid.First of all,the evaluation model for EMS disaster recovery system is developed followed by an optimization analysis of all the backup schemes available in the grid system.Then,an alternate monitoring/dispatch interbackup scheme based on the unified dispatch data net is presented.In light of the scheme for integration inter-backup,the disaster recovery system structure is set up based on the cloud platform and such cloud calculation techniques as virtualization and service rendering capable of effective protection for current resources of disaster recovery software and hardware.In the meantime,the current resources of backup software and hardware are made compatible.To meet the needs of the four levels of backup basic software,basic service,support application and application service,a series of inter-backup system solution schemes based on the unified management interface,system incremental synchrony,grid centralized control and unified management of dynamic extent have been designed.
