摘　　要：三相不平衡是重要的电能质量问题,是电能质量重要指标之一。提出了一种实用的三相不平衡度检测方法,给出了三相不平衡度测量的思路和程序框图,该方法程序简单,检测结果显示直观,硬件实现容易。在LabVIEW8.5软件中进行了实验仿真,证明了该方法具有一定的可行性和实用性。Three-phase imbalance, the important power quality problem is one of the important indicators of power quality. A method of practical three-phase unbalanced detection was presented, the idea of unbalanced three-phase measurement and program diagrams given. The procedures are simple, test results show intuitive and it is easy to realize the hardware. Simulation experiments in LabVIEW8.5 software prove that this method has certain feasibility and practicality.
