摘　　要：为实现对外场设备中电源谐波的快速准确监测,提出了一种基于Labwindows/CVI的通用谐波监测系统设计方案。系统采用便携式工控机作为硬件平台,软件采用Labwindows/CVI软件作为开发平台,用来实现数据的采集、分析与处理等功能,并将小波补偿的加窗插值F F T算法用于进行谐波分析,提高了谐波分析精度。In order to realize the requirement of fast and veracious harmbnic test for the power system used in the outfield, the design of power harmonic test system based on the Labwindows/CVI is introduced in this paper. The system adopts the portable computer and high speed data acquisition board, and the design of system software adopted virtual instrumentation technology can realize the functions including data acquisition, data processing, and so on. The system adopts FFT algorithm based on window functions and inter0olation to analysis harmonic, which can increase the precision of the harmonic analysis.
