| 摘 要： | 针对现有电能质量检测装置只适用于三相四线制电力系统，在分析牵引供电系统多达16路电量信号时，不能对各电量信号间进行相关性分析的不足，以LabVIEW为平台开发了一套适合牵引供电系统特点的电能质量检测与分析程序。该系统实现了多路同步信号采集；利用三点法实现对牵引供电系统频率的测量、对称分量法精确计算牵引供电系统负序含量、离散傅里叶变换（DFT）实现s级谐波和间谐波检测；同时完成5类稳态电能参数的实时计算、存储、统计分析、报表等功能模块，并具备对暂态电能质量事件捕获、分析等初步功能，满足了铁路牵引供电不同供电方式下实时同步检测的要求。

| Abstract: | The power quality testing devices available are only applicable to three-phase four-wire power system, and when power parameters are analyzed, the correlation between them can＇t be reflected. This paper mainly introduces a system framework and the basic functions realization based on LabVIEW. The system adopts the Art PCI2008 data simultaneous acquainting card, applies typical algorithm to realize the power parameters detection real-time, and realizes data computation, storage, statistical analysis, report and other functional mod- ules with database technology. This device also has the steady-state power quality detection and analysis capabil- ities, and the initial function ability of the transient power quality event capturing, and analyzing, thus meeting the real-time synchronization detection under different power supply modes. |
