摘　　要：本文是利用虚拟仪器的思想,对交流侧电流、电压的波形进行测量并对谐波产生机理进行分析,从而实现对交-直-交系统交流侧的运行品质评价。通过对传感器的选择及其信号处理电路和数据采集系统程序设计,实现系统对交流侧电气性能参数的采集。这里的数据采集是通过数据采集卡来实现的,编程语言是LabVIEW,使用虚拟仪器的思想来构建整个数据采集系统,先通过信号发生器来发生信号从而进行采集,然后对于交流侧整流器这部分电流电压波形进行采集。This system is using the ideas of virtual instrument, to measure the ac current, voltage waveform and the mechanism of harmonic analysis, so as to realize the orthogonal system of the ac running quality evaluation. Through the selection of the sensor and its signal processing circuit and data acquisition system program design, the system can collect the electrical performance parameters of the ac side. The data acquisition is realized through data acquisition card, programming language LabVIEW, using the idea of virtual instrument to build the data acquisition system, first struck by signal generator, signal acquisition, then this part for ac rectifier current voltage waveform acquisition.
