  • 摘要: 针对现有的谐波在线检测分析装置价格昂贵的问题,设计了一种简易的谐波在线检测分析系统。该系统采用数字信号处理器TMS320F2812搭建谐波检测装置电路,完成高速数据采集和传输任务;基于LabVIEW虚拟仪器开发了上位机系统,可对检测出的谐波进行实时显示和谐波FFT分析。该系统结构简单,操作容易,实验结果验证了该系统的有效性。

     

    Abstract: For problem that current harmonic detection and analysis devices are too expensive, a simple on-line harmonic detection and analysis system was designed. The system uses digital signal processor TMS320F2812 to build circuit of harmonic detection device, which could collect and transmit harmonic data fast, and adopts LabVIEW virtual instrument to develop upper computer system, which could display detected harmonic real-timely and do harmonic FFT analysis. The system has simple structure and convenient operation. The experimental result showed validity of the system.
