Abstract: In this paper, a PC-based Virtual Instrument (VI) for power analyzer is developed. Instead of theoretical research, a practical VI that can be integrated into existent 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 non-commercial use.

摘要：本文开发了一种基于PC虚拟仪器（VI）的功率分析仪。不同于理论研究，一款实用的虚拟仪器可以集成于开发好的虚拟仪器系统当中。在本文中，功率分析仪功能包括谐波分析仪和瞬时功率测量。这一款预开发的的虚拟仪器是基于LabVIEW（实验室虚拟仪器工程工作台）语言平台下，以微软 Windows 95/98的操作系统为开发环境。预实现的方法扩展能力要根据用户的要求。本文为功率分析仪开发了一些虚拟仪器模块，使用这些虚拟仪器模块就像使用软件集成电路（IC）一样。本文开发的所有虚拟仪器模块都是免费的非商业用途。
