摘　　要：为节约电力信息数据的存储开销、提升信息参量的压缩比数值,针对电力信息数据多通道采集与自动备份方法展开研究。根据电压与电流的有效值确定畸变因数、功率因数的实值表现量,完成对电力信息数据的多通道采集。在此基础上,统计电力信息流量水平,通过数据模式匹配的执行方法求解备份编码阈值,实现对电力信息数据的自动备份。实例分析结果表明,上述方法可在保障电力信息数据高质量压缩的基础上节约信息参量的存储开销,证明其具有较高的可行性。In order to save the storage cost of power information data and improve the compression ratio of information parameters,the method of multi-channel acquisition and automatic backup of power information data is studied.According to the effective value of voltage and current,the real value representation of distortion factor and power factor is determined,and the multi-channel acquisition of power information data is completed.On this basis,the power information flow level is counted,and the backup code threshold is solved by the implementation method of data pattern matching to realize the automatic backup of power information data.The result of example analysis shows that the above method can save the storage cost of information parameters on the basis of guaranteeing the high quality of power information data compression,and proves its high feasibility.
