摘　　要：研究一种基于虚拟仪器的用于检测变电站接地网状态的矢量电压表,通过确定接地网的可及节点,输入交流激励,用虚拟仪器程序配合数据采集卡采集各节点实时信号;利用Matlab与LabVIEW混合编程,将采集的数据输入检测程序,能做到实时显示信号的幅度与相位,依据采集的信息以及诊断结果对地网状态进行判断。We study a vector voltmeter for detecting substation ground grid state, through determining the reachable junctions of the ground grid, and using virtual instruments program combined with data acquisition to acquire the real time signal of each junction. By using Matlab and LabVIEW mixed programming, we put the data into detection program, and can display the signal amplitude and phase real-timely. We can diagnose the state of the ground grid based on the collecting information and diagnose program.
