摘要
故障测距是在线路两端的变电站利用测量到的电压、电流的实时数据计算故障点,这就需要对大量的采样数据进行处理．针对这一问题,介绍了将采集到的数据文件转换成MAT文件及VB调用 MATLAB的详细步骤;并且利用这项技术,以 VB编写主界面,调用 MATLAB完成故障分析和波形显示的功能,从而缩短了程序开发周期和减少了程序员的工作量．
Fault locating is performed by making use of real-time current data and voltage data measured at substations on both ends of transmission line; therefore,a large number of sample data have to be dealt with. In view of this problem, specific procedures of transforming data files acquired into MAT file and calling MATLAB by means of VB are introduced. This technique can help to compile main interface in terms of VB and make use of MATLAB to analyse faults and display waveform . Accordingly, cycles of developing programs can be shortened and heavy load of programmers can be lightened.
