针对以硬件为核心传统的电能质量监测仪，它具有开发周期长，扩展性能差，维护成本高等缺点。基于LabVIEW软件开发平台，设计了虚拟电能质量监测系统，通过模拟电网实现了电压偏差、频率偏差、三相不平衡度及电网谐波分析等电能质量指标并对其实时监测，以满足电力系统日益增加的测试需求，提高电网运行效益。

The traditional core hardware power quality monitor has such disadvantages as long development cycle , poor extended performance , and high maintenance costs .Based on Lab-VIEW software development platform , virtual power quality monitoring system was designed . By means of the simulating grid , power quality index deviations such as bias voltage , fre-quency , phase imbalance , and harmonic analysis had been achieved and monitored in order to meet the increasing test requirements of electricity system , and improve the operational ef-ficiency of the power grid .
