摘要
本文采用LabVIEW图形化软件编程实现了原来用硬件实现的FFT变换、滤波、信号的缩放等一系列功能。硬件方面采用具于PCI总线的PC和传感器电路。谐波是电能质量问题的重要方面,本文重点对谐波进行分析,并给出了相应的实现方法。
Graphical programming in LabVIEW can realize a series function like FFT transform, filtering and Signal scaling that is used to be achieved by hardware design. Hardware design in this paper includes PC and sensor circuit based on PCI bus. Harmonic is an important issue in power quality and is also the focus point in this paper. Relevant implement methods are also given.
