摘　　要：针对传统方法在恢复电网信息系统数据时存在的恢复效果不佳等问题,提出基于优先级分配策略的电网信息系统数据恢复方法。分析电网信息系统架构,获取电网信息系统数据丢失场景。结合插补区间连续丢失数据奇偶性动态变化,匹配不同优先策略,使物理损坏情况下的数据得以恢复。依据文件查找流程,恢复逻辑损坏数据。实验结果表明,采用所提方法恢复电网信息系统数据时,恢复的数据准确度较高,且耗时较短,为电网信息系统数据安全恢复提供了一定帮助。In order to solve the problems of traditional methods in restoring the data of power grid information system,a data recovery method based on priority allocation strategy is proposed.Analyze the structure of power grid information system and obtain the scene of data loss of power grid information system.Combined with the dynamic change of the parity of the continuous missing data in the interpolation interval,different priority strategies are matched to recover the data in the case of physical damage.According to the file search process,recover the logical damaged data.The experimental results show that when the proposed method is used to recover the grid information system data,the accuracy of the recovered data is high and the time⁃consuming is short,which provides some help for the data security recovery of grid information system.
