摘要
本文开发了一种基于pc机的功率分析仪虚拟仪器。本文不是进行理论研究,而是开发一种可以集成到现有VI系统中的实用VI。本文开发的功率分析仪功能包括谐波分析和瞬时功率测量。本文提出的虚拟仪器系统是在MS Windows 95/98操作系统的工作平台下,基于LabVIEW (Laboratory Virtual Instrument Engineering Workbench)语言开发的。该方法的能力可以根据用户的需求进行扩展。本文开发了一些功率分析仪的子可视设备,并利用这些子可视设备实现了软件集成电路的思想。论文中开发的所有子vis都是免费的非商业用途。
A LabVIEW based virtual instrument for power analyzers
In this paper, a PC-based virtual instrument (VI) for a power analyzer is developed. Instead of theoretical research, a practical VI that can be integrated into an existing VI system is developed. The functions of power analyzer developed in this paper include the harmonic analyzer and instantaneous power measurement. The proposed VI is based on the LabVIEW (Laboratory Virtual Instrument Engineering Workbench) language under the workbench of the MS Windows 95/98 operating system. The capability of the proposed method can be expanded according to the requirements of users. Some sub-VIs for the power analyzer are developed in this paper and the idea of software integrated circuit (IC) can be achieved by using these sub-VIs. All sub-VIs developed in the paper are free for noncommercial use.
