摘　　要：为了过滤故障录波装置产生的数据文件中的无效数据,以提高传输效率和有利于对故障的快速分析,介绍了PDS-781系列电力系统故障录波装置中实现的录波数据智能过滤技术,通过对信息的分类、原始录波文件的附加信息及可定制的过滤规则库的集中判别,对原始录波文件进行智能过滤,将与故障(或异常)相关的信息进行有效提取,提高了数据的远传效率。实际测试结果表明精简数据文件大小仅为原始文件的25%左右。在实际应用中,通过定制不同的规则库可实现预期的过滤,具有很高的灵活性。In order to filter the useless message from the data file of DFR（Digital Fault Recorder） for improving transmission efficiency and fast fault analysis, the intelligent data filtration method used in PDS-781 series digital fault recorder is developed. To enhance the remote data transfer efficiency of RTU（Remote Terminal Unit）, the fault/abnormality related information is intelligently and effectively extracted from the original recorded wave file by using the information classification and the centralized identification of the additional information and filtration rule library. Test results show that, the filtered data file is only 25% of the original document in size. The filtration rule library is customizable to reach the expected filtering effect with higher flexibility.
