基于LabVIEW的电力系统自动化虚拟实验平台设计 虚拟仪器是在计算机基础上通过增加相关硬件和软件构建而成的、具有可视化界面的仪器，融合了测试理论、仪器原理和技术、计算机接口技术、高速总线技术以及图形软件编程技术于一体 本文首先阐述了虚拟仪器技术的现状及以后的发展趋势，探讨了虚拟仪器的相关技术、LabVIEW的相关知识，然后阐述了有关电力系统实验平台的相关理论，给出了电力系统实验平台的相关图示。在分析本设计功能的基础上，介绍了程序模块化设计、LabVIEW的多线程等技术，最后给出了设计的前面板及程序框图。 本设计虚拟了一个系统电源与发电机的并网的全过程，根据相关电力系统知识做出了一个完整的实验平台。 关键字：虚拟仪器；电力系统；LabVIEW；实验平台。 Design automation of electric power systems of virtual experiment platform based on LabVIEW Abstract Virtual instrument is based on computer related hardware and software is built up, with the visual interface of the instrument, which combines the test theory, theory and technology equipment, computer interface technology, high-speed bus technology and graphics software programming technology is equal to one, many functions to achieve the instrument by using the digital computer processing ability strong., breaking the traditional instruments of the framework, the formation of a new instrument model. This paper first introduces the development trend of the present situation of electric power system and virtual instrument technology and the future, knowledge about relevant technology, virtual instrument LabVIEW, and then expounds the theory on the experimental platform of power system, given the relevant graphic experiment platform for power system. Based on the analysis of the design function, introduces the module design, LabVIEW multithreading technology, the front panel and the programming flow diagram are given. The design of virtual the whole process of a power system and generator grid-connected power system, according to the knowledge of a complete experimental platform to make. Key words: Virtual Instrument; Power System Automation; LabVIEW; Experimental Platform. 目录 1 绪论 1 1.1 引言 1 1.2 技术背景 1 1.2.1 电力系统自动化平台的发展现状 1 1.2.2 虚拟仪器的国内外现状 2 1.3 本课题相关理论 4 1.4 虚拟仪器的相关技术 5 1.4.1 虚拟仪器的概念 5 1.4.2 虚拟仪器的组成及与传统仪器的对比 5 1.4.3 虚拟仪器的硬件技术 6 1.4.4 虚拟仪器系统组建方案 8 1.4.5虚拟仪器的软件技术 9 1.5 LabVIEW的相关技术 10 1.5.1 LabVIEW的基本概念 10 1.5.2 LabVIEW编程相
