摘　　要：介绍LabVIEW与Multisim的基本功能和进行交互仿真的方法,并且基于LabVIEW和Multisim联合仿真虚拟出电能质量监测系统,节省了硬件资源。通过模拟三相电路实现了电压偏差、频率偏差、三相不平衡度及电网谐波分析等电能质量指标的实时监测,最终结果表明基于LabVIEW与Multisim联合仿真的系统测量精度高,准确性好,也可用于其他测量领域。This article describes the basic functions of LabVIEW and Multisim and interactive simulation methods,and based on Lab VIEW and Multisim co-simulation,and save the hardware resources. We design virtual power quality detection system which achieve real-time monitoring of power quality indicators such as voltage deviation,frequency deviation,phase imbalance and grid harmonic analysis by simulating a three-phase circuit. The final results show that the co-simulation systembased on LabVIEW and Multisim is featured with high accuracy. It can also be used for other measurement.
