摘　　要：小波分析是电力系统暂态信号分析的一种新兴工具,本文以LabVIEW和Microsoft Visual C++为平台设计了一套新型的电力暂态信号小波分析仪,其功能包括数据采集、小波变换、小波变换后处理和应用等。文中利用MATLAB仿真数据和实际牵引供电的电压数据对分析仪的功能进行测试,结果表明该分析仪是可行的,具有很高的实际应用价值。Wavelet analysis is a new tool for electric power transient signal analysis. A new type electric power transient signal wavelet analysis instrument based on LabVIEW （laboratory virtual instrument engineering workbench） and Microsoft Visual C ＋＋ is designed in this paper. The functions, such as data sampling, wavelet analysis, postprocessing and application are realized in the instrument. The instrument was tested with MATLAB simulated data and the voltage data of traction power system. Test result shows its feasibility and practicality.
