Abstract:

设计了基于虚拟仪器技术的电能质量分析仪校准检测系统,并将其应用于多种电能质量分析仪的校准检测。系统采用LabVIEW编程实现,通过虚拟仪器软件体系(virtualinstrumentssoftwarearchitecture,VISA)库函数组件、可编程仪器标准命令(standardcommandsforprogrammableinstruments,SCPI)、仪器自带驱动以及所需的硬件接口卡和数据总线来完成PC机与各相关仪器之间的数据通信。系统功能包括标准源设置、仪器控制和测量数据的存储分析。实验和计算结果表明,该系统可以完成各项电能质量指标的校准检测,在实际校准检测中,显著提高了校准检测的效率,减小了人员误差。
