| 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. |

| Abstract: |
| 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 ident... |
