利用虚拟技术提高电力实时信息系统可用性

To improve availability of real-time information systems for power systems by using virtual technology

电力实时信息系统对电力系统安全运行具有重要作用,高可用性电力实时信息系统架构是电力实时信息系统稳定运行的基础。针对实时信息系统的各种状态,利用n维向量表示实时信息系统的状态,然后用可辨识矩阵得到系统可用性状态判断规则。将规则融合到系统架构中得到电力实时信息系统高可用性架构。

The high-availability structure of the real-time information system for power systems is considered as the foundation for stable operation of the real-time information system.In the paper,the n-dimension vector was used to express the status of the real-time information system,and the discernibility matrix was applied to obtaining the judgment criteria for the availability status of the system.The high-availability structure of the real-time information system for power systems could then be achieved through integrating the criteria into the system framework.
